Rise and Spread of Islam | ICSE Class 7 History & Civics Notes

This note covers the Arabian setting of Islam, a religion centred on belief in one God; Muhammad’s life and teachings; basic religious practices; the migration to Medina and return to Mecca; leadership after Muhammad; the spread of rule by followers of Islam; ruling families; and exchanges of knowledge between regions.

What was the background in Arabia before Islam?

Arabia is the peninsula in south-western Asia where Islam began. A peninsula is land surrounded by water on three sides. Mecca and Medina lie in its western part, near the Red Sea. These places connect the geographical setting with the beginnings of the faith.

How did people live?

Arabian society included tribes, communities linked by ideas of common descent and loyalty. Some people lived as nomads, moving with their animals instead of remaining in one settlement. Others lived in towns or cultivated land where water was available.

Bedouins were nomadic Arab groups. Their way of life differed from that of settled merchants, who bought and sold goods. This distinction matters: the population of Arabia did not share one occupation or one pattern of settlement.

Mecca was a centre of trade and pilgrimage. A pilgrimage is a journey to a place regarded as holy. The Kaaba, a sacred shrine in Mecca, already drew worshippers before Islam. Many people worshipped several deities, meaning gods, while Jewish and Christian communities also existed in Arabia.

Why does this setting matter?

Polytheism means belief in many gods; monotheism means belief in one God. Muhammad’s monotheistic teaching challenged the worship of many deities. Tribal loyalties also formed part of the background against which a community united by religious belief developed.

Before Islam, Arabia did not form one unified state embracing all its tribes. Bringing Arabian groups under a common political authority later helped make expansion beyond the peninsula possible. Political authority means the power to govern a community and enforce decisions.

Arabia is labelled between the Red Sea and the Persian Gulf. Medina appears north of Mecca. Damascus and Baghdad are also marked. Use the map to distinguish the two Arabian holy cities from the later centres of government.

Reference: NCERT Class 11 Map 2

The map gives locations, not a timetable of religious change. Locating cities helps explain movement, but a place appearing on a map does not tell us when its inhabitants adopted a faith.

What do we learn about Muhammad’s birth and early life?

Muhammad, also spelt Mohammad, was born in Mecca about 570 CE. CE means Common Era, the dating system used here. The word “about” matters because the birth year is approximate. Muslims, the followers of Islam, regard Muhammad as a prophet, a person who conveys God’s message.

What was his early background?

Muhammad belonged to the Quraysh, the tribe associated with Mecca. He lost his parents in childhood and was cared for by relatives. As a young man he worked in trade. He later married Khadija, a merchant who supported him.

His early life therefore belongs to the setting of a trading town within Arabian tribal society. Remembering that setting connects the individual life with the wider history. Islam emerged among people whose lives included trade, family responsibilities and established religious practices.

How did his preaching begin?

According to Islamic belief, Muhammad began receiving revelations, messages from God, through the angel Gabriel around 610 CE, during a retreat in the cave of Hira near Mecca. An angel is understood in this belief as a heavenly messenger.

Muslims believe these revelations form the Qur’an, Islam’s holy book. Muhammad taught belief in one God, called Allah in Arabic. Arabic is the language in which the Qur’an is written. Belief in Muhammad’s role as messenger does not mean worshipping him as God.

His teaching met opposition in Mecca. Challenging established worship also challenged people attached to the religious and social order of the town. The opposition forms the background to his later migration, meaning movement from one place to another to settle.

Keep the stages separate: birth about 570 CE, early life in Mecca, and the beginning of revelations around 610 CE. The migration was a later event. Combining these stages into one date would hide the development from childhood to religious leadership.

What are Islam’s teachings and five basic principles?

The central belief of Islam is one God. Muslims recognise Muhammad as God’s messenger. This belief provides the basis for religious duties and for teachings about responsibility towards other people.

What does each pillar mean?

The five pillars are five basic commitments of the faith. Those who adopted Islam accepted them in principle. That qualification is important: shared religious principles do not mean that every person’s daily behaviour or every local custom is identical.

Fasting involves going without food and drink from dawn to sunset during Ramzan, subject to religious exemptions. The exemptions mean it is inaccurate to claim that every Muslim, regardless of age or health, must fast in exactly the same circumstances.

How do these principles connect belief and conduct?

Shahada expresses belief; salat gives regular expression to worship. Zakat connects religious duty with material help. Sawm involves self-restraint. Hajj connects worshippers with the holy city of Mecca. Each has a distinct meaning, even though they belong to the same framework.

Islam teaches compassion, honesty and concern for people in need. These teachings concern conduct as well as worship. Compassion means recognising suffering and responding with care. Helping others is therefore relevant to understanding the social meaning of religious practice.

Eid-ul-Fitr is the festival marking the end of Ramzan. It is associated with communal prayer, celebration and giving. A mosque is a Muslim place of worship. Neither a festival nor a building is a substitute for naming one of the five pillars.

Shared principles were often combined with differences arising from local customs and religious traditions. Keep both parts of the picture: Muslims shared central beliefs, while the ways communities expressed their faith could differ. Difference in custom does not by itself establish difference in every basic belief.

Definition: The five pillars link declaration of faith, prayer, almsgiving, fasting and pilgrimage. They describe distinct commitments, not five names for the same religious act.

Why were the Hijrat and return to Mecca turning points?

In 622 CE, Muhammad and his companions left Mecca for Medina. This migration is called the Hijrat, also written Hijra or Hijrah. “Hizrat” is another spelling. Medina had previously been known as Yathrib.

What changed at Medina?

Opposition in Mecca provided the background to the migration. At Medina, Muhammad became the leader of an organised religious and political community. The move therefore changed the conditions in which his followers could practise their religion and build a common life.

The umma means the community of Muslim believers. Its bond was shared faith, which could connect people from different tribal backgrounds. Membership of a religious community and membership of a tribe were different kinds of belonging.

The Hijrat is the starting point of the Hijri era, the era used for the Islamic calendar. An era is a system of counting years from a particular starting point. The Hijrat marks migration, not Muhammad’s birth or the first revelation.

What happened on the return to Mecca?

In 630 CE, Muhammad returned to Mecca and brought it under his authority. The Kaaba was cleared of idols, images or objects worshipped as deities. It became the central sanctuary for the worship of one God in Islam.

Mecca and Medina are both holy cities for Muslims. Mecca is associated with Muhammad’s birth, the Kaaba and the hajj. Medina is associated with the Hijrat and the growth of the early Muslim community. Their importance is connected, but their historical roles are distinct.

The sequence explains the turning point: opposition preceded migration; migration allowed the community to establish itself at Medina; the later return brought Mecca under Muhammad’s authority. The events of 622 CE and 630 CE should therefore remain separate in a chronological account.

Note: The Hijrat was from Mecca to Medina in 622 CE. The return to Mecca occurred in 630 CE. Reversing the direction or exchanging the dates changes the meaning of both events.

How did different groups participate in the developing Islamic world?

The history of Islam includes people with different occupations, forms of authority and local traditions. The story extends beyond the lives of rulers. Distinguishing these groups helps explain how political expansion and everyday religious life were connected.

What part did tribes and early believers play?

Arabian tribes formed the social setting in which the early community developed. The emerging Islamic state brought tribes under its authority, first within Arabia and then around the Syrian desert and the edges of Iraq. Their unification was important for further territorial expansion.

Early believers shared religious commitments through the umma. Shared faith offered a connection across tribal backgrounds. This helps explain why the growth of the community involved a change in forms of belonging as well as a change in religious belief.

What part did rulers and armies play?

Rulers and armies extended political control. After Muhammad’s death, successors led the community and campaigns carried Arab rule into neighbouring regions. A campaign is a connected series of military operations. Military expansion concerns who governs a territory.

What part did merchants and other social groups play?

Merchants maintained contacts between distant places. Arab traders visited ports on the western coast of the Indian subcontinent. Among people who adopted Islam in the subcontinent were peasants, artisans, warriors and merchants. An artisan is a skilled maker of goods.

These varied groups show why religious history cannot be reduced to changes of dynasty. A dynasty is a succession of rulers from one family. The religion of a ruling family, the work of traders and the beliefs of local inhabitants are related but distinct subjects.

How did the caliphate begin after Muhammad’s death?

Muhammad died in 632 CE. Leadership of the Muslim community passed to successors called caliphs. A caliph was a successor to Muhammad as leader of the community, not a new prophet. The institution of leadership is called the caliphate.

Who were the early successors?

Abu Bakr became the first caliph. He was followed by Umar, Uthman and Ali. These four leaders are commonly called the Rightly Guided Caliphs. The title identifies the first group of successors in the conventional account of early Islamic history.

The problem of succession was practical as well as religious. Succession means the transfer of an office or position to another person. The community needed leadership after the death of the person who had guided its formation.

The caliphs dealt with government, the maintenance of unity and military activity. Holding political office differed from conveying revelation. This distinction prevents the mistaken conclusion that a caliph held exactly the same religious position as Muhammad.

How did the area under Muslim rule grow?

During 633 to 642 CE, Muslim armies took Syria, Palestine, Egypt, Iraq and parts of Iran. By 642 CE, large parts of the eastern Roman and Sasanian empires had fallen to the Arabs. “Large parts” does not mean every territory of both empires.

The eastern Roman Empire, also called the Byzantine Empire, was centred on Constantinople. The Sasanian Empire was the Iranian empire bordering it. These states help locate the early conquests beyond Arabia.

The caliphate thus joined leadership of the religious community with rule over expanding territories. As those territories grew, the rulers governed populations with varied traditions. The existence of Muslim government should not be confused with the claim that every subject immediately became Muslim.

Follow the sequence from Muhammad’s death in 632 CE to the campaigns of 633 to 642 CE. The growth of the state continued under his successors; it was not completed within his lifetime.

Why did Islam and Muslim political power spread beyond Arabia?

Several connected processes explain the spread. Political expansion means extending a state’s rule. Conversion means adopting a religion. These processes could be related, but they were not identical and did not necessarily occur at the same speed.

What made early territorial expansion possible?

1. Unification within Arabia: bringing numerous tribes under the emerging Islamic state provided a basis for expansion beyond the peninsula.
2. Organised military campaigns: armies carried that authority into neighbouring regions, including Syria, Egypt and Iraq.
3. Conflict between neighbouring empires: the eastern Roman and Sasanian states had fought repeated wars before the Arab advances.
4. A faith crossing local boundaries: Islam could appeal to people of different backgrounds and languages, helping create connections within a widening world.

The earlier wars form part of the political setting. They do not provide a complete explanation on their own. Arabian unification and the organisation of the new state must also be included when explaining how expansion became possible.

Where did the expansion reach?

By 642 CE, Arab victories had brought large parts of neighbouring empires under their control. Later conquests extended as far as Spain, Sind and Central Asia. Sind is the region of the lower Indus; Central Asia lies inland between the major regions of eastern and western Asia.

The Arab capture of Carthage, a city in North Africa, occurred in 698 CE. The Arab invasion of Spain followed in 711 CE. These examples show the reach of expansion beyond the Arabian peninsula.

Trade also connected communities over long distances. Arab merchants frequented ports on the western coast of the Indian subcontinent. Such contacts provide a different setting for the circulation of religious ideas from the battlefield or the ruler’s court.

Distinguish the evidence needed for each claim. A conquest date identifies a change of political control. Evidence of religious practice concerns what people believed and did. A careful explanation of spread includes both, without turning a military victory into proof of immediate universal conversion.

How did the Umayyad and Abbasid dynasties compare?

The Umayyads and Abbasids were ruling families associated with successive phases of the caliphate. Their history shows the development of an extensive empire, a state ruling many territories and peoples, after the earliest Muslim community.

What characterised Umayyad rule?

The Umayyad caliphate in Syria lasted from 661 to 750 CE. Muawiya established the dynasty, with Damascus as its capital. A capital is the chief centre of government. Under the dynasty, succession became hereditary, meaning that power passed within the ruling family.

Territorial expansion continued during this period. The capture of Carthage in 698 CE and the invasion of Spain in 711 CE belong within the Umayyad period. Placing these events within the dynasty’s dates links individual campaigns to the wider political sequence.

What changed under the Abbasids?

The Abbasids overthrew the Umayyad caliphate in 750 CE. Baghdad became their capital after its foundation by the caliph al-Mansur in 762 CE. It developed into a major centre of commerce and culture. Commerce means the exchange of goods through trade.

In 1258 CE, the Mongols captured Baghdad, ending the Abbasid caliphate there. The Mongols were a people from Central Asia whose rulers built a vast empire. The fall of this political centre did not end Islam as a religion.

Use the comparison to keep cities and periods distinct. Mecca and Medina were the holy cities central to Islam’s beginnings. Damascus and Baghdad were major centres of later government. Religious importance and administrative importance describe different roles, even when a city can have both.

A change of dynasty altered who governed the empire. It did not create a wholly new religion or remove the central religious commitments already shared by Muslims.

What was the wider cultural impact of the spread of Islam?

The spread of Islam affected political life, religious practice, trade and learning across many regions. Cultural exchange means the movement and adaptation of ideas, knowledge and practices between communities. Its history cannot be explained through military victories alone.

How did learning travel?

Arab translators preserved and translated ancient Greek manuscripts, books written by hand. Later European scholars encountered Greek works through Arabic translations. Other works by Arabic and Persian scholars were translated for circulation among Europeans. Persian is a language associated with Iran.

This exchange included natural science, mathematics, astronomy, medicine and chemistry. Astronomy is the study of celestial bodies, such as stars and planets. Translation allowed readers to encounter ideas first expressed in languages they could not themselves read.

Ibn Sina, a physician and philosopher, and al-Razi, the author of a medical encyclopaedia, are examples of Muslim scholars whose writings became known in Europe. A physician practises medicine. A philosopher studies fundamental questions about knowledge and existence. An encyclopaedia collects organised information on a subject or range of subjects.

These examples concern the wider legacy of the Islamic world over time. They should not be placed in Muhammad’s lifetime simply because they belong to the same broad history. Religious beginnings and later scholarly achievements are different stages.

Why should cultural history include exchange?

Baghdad’s importance as a commercial and cultural centre illustrates the connection between cities, trade and learning. Wider links connected Asia, North Africa and Europe through commerce and the circulation of skills. These connections did not require every region to belong to one political state.

Legacy means an influence that continues beyond its original period. The legacy here includes the communication of knowledge across linguistic and regional boundaries. Recognising exchange gives a fuller explanation than attributing every achievement to one isolated civilisation.

The social dimension also matters. Principles of compassion and welfare draw attention to relationships between people. Studying religious history involves understanding such ideals while also examining how communities and political institutions changed over time.

What does a timeline show about the rise and spread of Islam?

A timeline arranges events in chronological order, meaning the order in which they occurred. All dates below use CE. “About” marks an approximate year; “c.” means circa, or about. A date range indicates a period. The abbreviated range 633-42 means 633 to 642.

Read the timeline as connected stages: Muhammad’s life, the growth of the early community, government by successors, and later dynasties. A date becomes meaningful when attached to an event and its place in that sequence.

Some entries overlap because they describe different things. The year 711 CE falls within the Umayyad period of 661 to 750 CE. The dynasty’s date range and the invasion date therefore belong together without being interchangeable.

What sources help us study beliefs, events and historical change?

Historical sources are materials used as evidence about the past. Different sources answer different questions. A religious text, a record of events and a surviving building do not necessarily tell us the same kind of information.

What can written sources tell us?

The Qur’an is central to understanding Islamic belief and teaching. The hadith are traditions recording Muhammad’s remembered words and deeds. They help explain the importance given to his example in Muslim religious life.

Biographies, accounts of a person’s life, help organise information about Muhammad’s career. Chronicles, accounts arranged in time order, help historians reconstruct rulers, events and political changes. Religious teaching and a narrative of events answer different historical questions.

How do dated examples place evidence in context?

The Great Mosque at Damascus was completed in 714 CE. Its completion places this religious building within the Umayyad period, giving a dated example of material evidence alongside written accounts.

Ibn Sina, who lived from 980 to 1037 CE, was a physician and philosopher of Bukhara. Known in Latin as Avicenna, he was among the Muslim writers respected in Italy, illustrating the circulation of scholarly writings beyond their original setting.

Ibn Rushd, who lived from 1126 to 1198 CE, was a philosopher of Spain, known in Latin as Averroes. He sought to reconcile philosophical knowledge with religious belief; Christian thinkers adopted his method.

These dates identify the scholars’ lifetimes, not the dates of individual manuscripts. Their writings and the adoption of their ideas help trace intellectual exchange, while placing this evidence centuries after Muhammad’s lifetime.

How should evidence be assessed?

Material evidence consists of physical remains, such as coins, inscriptions and buildings. An inscription is writing placed on a durable surface. These remains can help historians investigate authority, language, worship and the places where people lived.

A historian asks who produced a source, when it was produced and what purpose it served. Comparing different kinds of evidence helps separate an author’s intention from the event or practice being described.

A statement of religious duty explains an ideal; it does not establish that every person followed it identically. Likewise, evidence that a ruler controlled a city does not establish the faith of every inhabitant. Matching a claim to suitable evidence helps preserve these important distinctions.

Useful historical questions therefore include both “What happened?” and “How do we know?” The first builds a sequence of events; the second tests how far the available evidence supports the explanation.

• Misconception: The fall of Baghdad in 1258 CE ended Islam. Correct: It ended the Abbasid caliphate at Baghdad, not the religion or all Muslim communities.

Exam-style questions with model answers

Q1. Use these facts: Muhammad and his companions migrated from Mecca to Medina in 622 CE, and this event began the Hijri era used for the Islamic calendar. State the direction and date of the migration, then its calendar significance. [2 marks]

1. The migration was from Mecca to Medina in 622 CE.
2. It marked the starting point of the Hijri era used for the Islamic calendar.

Q2. Consider these statements: Muhammad taught belief in one God, Allah; he was regarded as God’s messenger; and religious giving supported people in need. Explain three aspects of the teaching shown by these statements. [3 marks]

1. Belief in one God expresses monotheism. The teaching directs worship towards Allah, rather than towards a number of different gods.
2. Muhammad’s position is that of God’s messenger. Recognising his authority as a messenger is different from treating him as God.
3. Giving support to people in need connects religious commitment with responsibility towards others. Religious life therefore includes social conduct as well as belief.

Q3. The five pillars are shahada, the declaration of belief in one God, Allah, and Muhammad as his messenger; salat, prayer five times daily; zakat, giving alms to those entitled to support; sawm, fasting during the month of Ramzan; and hajj, pilgrimage to Mecca for those physically and financially able. Explain each pillar in one separate point. [5 marks]

1. Shahada is the declaration of faith. It affirms belief in one God, Allah, and identifies Muhammad as God’s messenger, connecting belief with recognition of his message.
2. Salat is prayer, offered five times a day. This pillar gives worship a regular place in religious practice through repeated prayer.
3. Zakat is the giving of alms. It links religious commitment with material assistance and responsibility towards people entitled to receive support.
4. Sawm is fasting during the month of Ramzan. This pillar concerns a practice associated with that month, rather than the daily frequency of prayer.
5. Hajj is the pilgrimage to Mecca. Physical and financial ability qualify the obligation, so it should not be described as a journey everyone must make regardless of circumstances.

Q4. Use these facts: Muhammad died in 632 CE; Abu Bakr became the first caliph; a caliph led the community without becoming a new prophet; and campaigns during 633 to 642 CE took Syria, Palestine, Egypt, Iraq and parts of Iran. Describe four features of the transition after Muhammad’s death. [4 marks]

1. Muhammad’s death in 632 CE created the need for continuing leadership. The community’s political history therefore continued beyond his lifetime.
2. Abu Bakr became the first caliph. His accession began the sequence of successors who led the Muslim community after Muhammad.
3. The caliph’s office involved leadership of the community. It did not make its holder a new prophet or give him Muhammad’s identical religious position.
4. Military expansion continued in 633 to 642 CE. Syria, Palestine, Egypt, Iraq and parts of Iran were taken during these campaigns.

Q5. Compare these records: the Umayyad caliphate in Syria lasted from 661 to 750 CE and had Damascus as its capital; the Abbasids took power in 750 CE and made Baghdad, founded in 762 CE, their capital. Give three comparisons: sequence, capital and the significance of 750 CE. [3 marks]

1. The Umayyad caliphate came earlier, ruling in Syria from 661 to 750 CE. Abbasid rule followed when that family took power in 750 CE.
2. The major capitals were different. Damascus was the Umayyad capital, while Baghdad, founded in 762 CE, became the Abbasid capital.
3. The year 750 CE connects both records. It marks the end of the Umayyad caliphate in Syria and the Abbasid accession to power.

Q6. A historical account states that Arabian tribes were unified under a new state, armies conquered neighbouring territories, merchants maintained distant contacts, and people of different backgrounds adopted Islam. It also says conquest and conversion are distinct. Use these five statements to explain why the spread requires more than a list of battles. [5 marks]

1. Unifying Arabian tribes created a political basis for expansion. This was a process of organising authority within Arabia, which a list of external battles alone would omit.
2. Armies conquered neighbouring territories and extended the state’s control. Battles therefore explain an important part of the political expansion described in the account.
3. Merchants maintained contacts between distant communities. These connections belong to the movement of people and ideas, adding another dimension beyond military campaigns.
4. People of different backgrounds adopted Islam. Their adoption concerns religious belief within communities, so it requires attention to people as well as rulers.
5. Conquest and conversion are distinct processes. A military success establishes a change in political control but does not by itself prove that every inhabitant changed religion.

Q7. Arab translators preserved Greek manuscripts; European readers encountered Greek works through Arabic translations; Arabic and Persian scholarship also circulated in translation; and subjects included mathematics, astronomy and medicine. Explain four ways these facts demonstrate cultural exchange. [4 marks]

1. Preserving Greek manuscripts helped keep earlier writings available. The work of Arab translators connected knowledge from one setting with readers in another.
2. Arabic translations gave European readers access to Greek works. Knowledge could therefore travel through an intermediate language rather than directly from its original form.
3. The circulation of Arabic and Persian scholarship shows exchange involving additional bodies of knowledge. Translation was not limited to passing on Greek writings.
4. The subjects included mathematics, astronomy and medicine. The exchange therefore concerned several areas of learning rather than a single kind of text.

Key takeaways

• Islam emerged in Arabia, where tribal communities, nomadic groups, settled merchants and different religious traditions formed the background.
• Muhammad was born about 570 CE; Muslims regard him as God’s messenger and the recipient of the Qur’an’s revelations.
• The five pillars connect faith, prayer, almsgiving, fasting and pilgrimage, while local customs and practices could differ.
• The Hijrat took Muhammad and his companions from Mecca to Medina in 622 CE and began the Hijri era.
• After Muhammad’s death in 632 CE, caliphs led the community and political expansion continued beyond Arabia.
• The Umayyads ruled from Damascus; the Abbasids later made Baghdad a major centre of government, commerce and culture.
• Political conquest and religious conversion are distinct; a change of ruler does not prove everyone immediately changed belief.
• Translation, trade and scholarship connected communities and contributed to the wider cultural legacy of the Islamic world.

Test yourself

Why should Muhammad’s birth be dated “about 570 CE”?

The year is approximate, so removing “about” would make the claim more precise than the evidence supports.

What distinction does shahada make between Allah and Muhammad?

Allah is the one God in Islamic belief; Muhammad is his messenger, not an object of worship as God.

What are the five pillars?

They are shahada, the declaration of faith; salat, prayer; zakat, almsgiving; sawm, fasting during Ramzan; and hajj, pilgrimage to Mecca.

What distinguishes the events of 622 CE and 630 CE?

The Hijrat from Mecca to Medina occurred in 622 CE. Muhammad’s return to Mecca occurred in 630 CE.

How did a caliph differ from a prophet?

A caliph succeeded Muhammad as leader of the community. Holding that office did not make him a new prophet.

Which cities connect with Umayyad and Abbasid government?

Damascus was the Umayyad capital; Baghdad became the Abbasid capital and a major commercial and cultural centre.

Why is a conquest date insufficient evidence of universal conversion?

It establishes a change in political control. It does not establish the religious beliefs of every person living in the territory.

How did translation contribute to the wider cultural legacy?

Translations helped circulate Greek writings and Arabic and Persian scholarship, connecting readers across languages and regions in several fields of learning.
