Islam is one of the world’s major monotheistic religions, with over a billion followers known as Muslims. It emerged in the Arabian Peninsula in the 7th century AD and is based on the teachings of the Prophet Muhammad, who is considered the last and final messenger of God in a line of prophets that includes figures like Adam, Abraham, Moses, and Jesus.
To understand the history and origin of Islam, World History Edu explores the socio-political and religious context of Arabia before Islam, the life of Prophet Muhammad, the revelation of the Quran, and the early expansion of Islam.

The Quran
Pre-Islamic Arabia
Before the advent of Islam, the Arabian Peninsula was a region characterized by a diverse mix of cultures, religions, and tribal societies. The period before Islam is often referred to as the “Jahiliyyah,” or the “Age of Ignorance,” a term used in Islamic tradition to describe the state of moral and spiritual ignorance that existed before the revelation of Islam.
Tribal Society and Economy
Arabian society was primarily tribal, with each tribe acting as an independent social unit. Loyalty to one’s tribe was paramount, and intertribal conflicts were common. The harsh desert environment made survival difficult, leading to a culture that valued strength, courage, and hospitality.
Economically, the Arabian Peninsula had a mix of nomadic and settled populations. The Bedouins were nomadic tribes who lived in the desert, herding camels, sheep, and goats. In contrast, the settled populations lived in towns and cities, where trade played a significant role. Mecca, in particular, was a major trading center due to its strategic location along caravan routes and its status as a religious hub.
Religious Beliefs
Religiously, pre-Islamic Arabia was predominantly polytheistic. The Arabs worshiped a multitude of gods and goddesses, with each tribe having its own deities. The Kaaba, a cube-shaped structure located in Mecca, was a central shrine that housed idols of various gods and was a site of pilgrimage for many tribes.
In addition to polytheism, some monotheistic influences were present in pre-Islamic Arabia. Judaism and Christianity had established small communities in certain areas, and there were also Hanifs, who were monotheistic Arabs that rejected idolatry but did not follow any specific religion.

In 1303, the Templars lost their last base in the Middle East. They then relocated to Paris, France. Image: Temple Mount, located in the Old City of Jerusalem, has been venerated as a holy site in Judaism, Christianity, and Islam for thousands of years.
The Life of Prophet Muhammad

Prophet Muhammad and the Kabaah
The history of Islam is inextricably linked to the life of its founder, Muhammad ibn Abdullah, who was born in Mecca around 570 CE. His life and experiences form the foundation of Islamic beliefs and practices.
Early Life
Muhammad was born into the Hashim clan of the Quraysh tribe, a powerful and influential tribe in Mecca. His father, Abdullah, died before his birth, and his mother, Amina, died when he was six years old. As a result, Muhammad was raised by his grandfather, Abdul Muttalib, and later by his uncle, Abu Talib.
From a young age, Muhammad was known for his honesty and integrity, earning him the nickname “Al-Amin,” meaning “the trustworthy.” He worked as a merchant and was employed by a wealthy widow named Khadijah. Impressed by his character, Khadijah proposed marriage, and they married when Muhammad was 25 years old. Their marriage was a happy and supportive one, and Khadijah would later become the first person to believe in Muhammad’s prophethood.
The First Revelation
Muhammad often spent time in solitude, reflecting on spiritual matters. It was during one of these retreats, in the Cave of Hira on the outskirts of Mecca, that he received his first revelation in 610 CE at the age of 40. The angel Gabriel (Jibril in Arabic) appeared to him and instructed him to “Recite” or “Read” (in Arabic, “Iqra”).

Muhammad responded that he could not read, but the angel repeated the command and revealed the first verses of what would become the Quran:
“Recite in the name of your Lord who created—created man from a clinging substance. Recite, and your Lord is the most Generous—Who taught by the pen—taught man that which he knew not” (Quran 96:1-5).
This event marks the beginning of Muhammad’s prophethood and the start of Islam as a distinct religious movement.

The Early Years of Islam
Following the first revelation, Muhammad began to preach the message of Islam, calling people to monotheism and the worship of one God (Allah). He also emphasized moral and social reforms, including justice, compassion for the poor, and the rejection of idolatry.
Early Converts
Initially, Muhammad’s message was met with skepticism and resistance, but a small group of followers began to gather around him. Among the first converts were his wife Khadijah, his cousin Ali ibn Abi Talib, his close friend Abu Bakr, and his adopted son Zaid ibn Haritha. This small community of believers faced increasing hostility from the Quraysh tribe, who saw Muhammad’s teachings as a threat to their social order and economic interests, particularly the lucrative pilgrimage trade associated with the Kaaba.

Persecution and the Hijra
As the number of Muslims grew, so did the opposition from the Quraysh. The early Muslims were subjected to persecution, social ostracism, and economic boycotts. Some were tortured and even killed for their beliefs. Despite the hardships, the Muslim community continued to grow.
In 622 CE, after years of persecution, Muhammad and his followers were invited to move to the city of Yathrib (later known as Medina), about 320 kilometers north of Mecca. This migration is known as the “Hijra” and marks a turning point in Islamic history. The Hijra not only marks the beginning of the Islamic calendar but also the establishment of the first Muslim community under Muhammad’s leadership.
The Establishment of the Islamic State
In Medina, Muhammad took on the roles of both a religious and political leader. He established a constitution known as the “Constitution of Medina,” which outlined the rights and responsibilities of the various communities living in the city, including Muslims, Jews, and pagan tribes. This document is considered one of the earliest examples of a written constitution in history.
The Battles of Badr, Uhud, and the Trench
The Quraysh in Mecca viewed Muhammad’s growing influence with alarm and sought to crush the nascent Muslim community. This led to a series of military confrontations between the Muslims and the Quraysh.
- The Battle of Badr (624 CE): The first major battle between the Muslims and the Quraysh took place at Badr. Despite being outnumbered, the Muslims won a decisive victory, which bolstered their confidence and signaled that they could defend themselves.
- The Battle of Uhud (625 CE): The Quraysh sought revenge for their defeat at Badr and launched an attack on Medina. The Battle of Uhud was fought on the outskirts of the city. Although the Muslims initially had the upper hand, they ultimately suffered a setback due to disobedience within their ranks. However, the Quraysh did not pursue their advantage, and the battle ended inconclusively.
- The Battle of the Trench (627 CE): In a final attempt to defeat the Muslims, the Quraysh, along with several allied tribes, laid siege to Medina. Muhammad and his followers dug a trench around the city, which effectively neutralized the Quraysh’s cavalry. The siege lasted for several weeks, but eventually, the Quraysh and their allies were forced to withdraw. This victory marked a turning point, as it demonstrated the strength and resilience of the Muslim community.
The Treaty of Hudaybiyyah and the Conquest of Mecca
In 628 CE, Muhammad sought to make a pilgrimage to Mecca, but the Quraysh, still at odds with the Muslims, blocked their way. This led to negotiations, resulting in the Treaty of Hudaybiyyah, a ten-year truce between the Muslims and the Quraysh. The treaty allowed for the peaceful coexistence of the two parties and gave Muhammad and his followers the opportunity to spread Islam without fear of attack.
However, the treaty was broken by the Quraysh a few years later. In response, Muhammad gathered a large army and marched on Mecca in 630 CE. The city surrendered without a fight, and Muhammad entered Mecca triumphantly. He declared a general amnesty, sparing the lives of his former enemies, and ordered the destruction of the idols in the Kaaba, rededicating it to the worship of one God.
The conquest of Mecca marked the consolidation of Muslim power in the Arabian Peninsula. Many of the tribes in the region, seeing the success of Muhammad and his followers, began to embrace Islam.
The Final Years of Prophet Muhammad
After the conquest of Mecca, Islam spread rapidly throughout the Arabian Peninsula. Muhammad continued to lead the Muslim community, focusing on consolidating the gains of the previous years and spreading the message of Islam to neighboring regions.

The Farewell Pilgrimage
In 632 CE, Muhammad performed the Hajj (pilgrimage) to Mecca, known as the Farewell Pilgrimage. During this pilgrimage, he delivered a famous sermon, known as the Farewell Sermon, in which he summarized the key teachings of Islam and emphasized the importance of unity, justice, and equality among all Muslims. He also affirmed the sanctity of human life and property and called for the end of tribal vengeance and blood feuds.
Shortly after returning to Medina, Muhammad fell ill and passed away on June 8, 632 CE. His death marked the end of the prophetic era, but by this time, Islam had firmly taken root in the Arabian Peninsula, and the foundations for its future expansion were established.
The Dome of the Rock and its significance in Islam

Like the Al-Aqsa Mosque, the Dome of the Rock is located on the Mount Temple in the Old City of Jerusalem which is in East Jerusalem.
The Dome of the Rock, an iconic Islamic shrine in Jerusalem, features Quranic inscriptions that hold deep religious significance. These inscriptions, written in elegant Arabic calligraphy, adorn the interior and exterior of the structure.
The Dome of the Rock marks the spot where, according to Islamic tradition, the Prophet Muhammad ascended to heaven during the Night Journey (Isra and Mi’raj). The Quranic verses inscribed on the walls primarily emphasize the oneness of God (Tawhid) and the finality of Muhammad’s prophethood. These inscriptions serve both as religious text and as a visual reminder of the spiritual journey that Muhammad undertook, making the Dome of the Rock a sacred site for Muslims and a symbol of their faith.

The Early Caliphate and Expansion of Islam
After Muhammad’s death, the Muslim community faced the challenge of leadership succession. The community chose Abu Bakr, a close companion of Muhammad and one of the earliest converts to Islam, as the first caliph (successor). Abu Bakr’s caliphate marked the beginning of the Rashidun (Rightly Guided) Caliphate, a period of significant expansion and consolidation of Muslim rule.
The Ridda Wars and Unification of Arabia
Abu Bakr’s first major challenge as caliph was to deal with the Ridda Wars (Wars of Apostasy). Several tribes in Arabia, having pledged allegiance to Muhammad, renounced Islam after his death, refusing to pay zakat (charity tax) and returning to their pre-Islamic practices. Abu Bakr led military campaigns to bring these tribes back into the fold of Islam and successfully unified Arabia under Muslim rule.
The Conquests of the Byzantine and Sassanian Empires
With the Arabian Peninsula unified, the Muslim state turned its attention to the neighboring Byzantine and Sassanian empires. The rapid expansion of Islam in the 7th century CE was one of the most remarkable military and political transformations in history.
- Conquest of the Levant and Egypt: Under the leadership of Caliph Umar ibn al-Khattab (r. 634-644 CE), Muslim armies conquered the Levant (modern-day Syria, Jordan, Lebanon, and Israel) and Egypt, territories that had been under Byzantine control. Key battles, such as the Battle of Yarmouk in 636 CE, resulted in decisive Muslim victories and the collapse of Byzantine resistance in the region.
- Conquest of Persia: The Sassanian Empire, which ruled over Persia (modern-day Iran), was also targeted by the Muslim armies. The Battle of Qadisiyyah in 636 CE and the subsequent Battle of Nahavand in 642 CE led to the defeat of the Sassanian forces and the eventual incorporation of Persia into the growing Islamic empire.
The Spread of Islam and Cultural Integration
The rapid expansion of Muslim rule brought diverse peoples and cultures under Islamic governance. This period saw the integration of various cultural and intellectual traditions into the Islamic world. The new Muslim rulers generally allowed the conquered peoples to retain their religious practices, provided they paid the jizya, a tax levied on non-Muslims. This policy of tolerance facilitated the spread of Islam and the assimilation of different cultures into the Islamic civilization.
The Umayyad Caliphate (661-750 CE), which succeeded the Rashidun Caliphate, continued the expansion of the Islamic empire, reaching as far west as Spain and as far east as the Indus River in South Asia. The Umayyads established a more centralized form of governance, with Damascus as the capital, and further developed the administrative and military structures of the empire.

The Rashidun Caliphate reached its greatest extent under Caliph Uthman, in 654.
The Quran and Islamic Teachings
Central to the faith of Islam is the Quran, the holy book believed by Muslims to be the literal word of God as revealed to Muhammad. The Quran is composed of 114 chapters (surahs) and covers a wide range of topics, including theology, morality, law, and guidance for personal conduct.
The Compilation of the Quran
During Muhammad’s lifetime, the Quranic revelations were memorized by his followers and written down on various materials, such as parchment, bone, and palm leaves. After Muhammad’s death, the first caliph, Abu Bakr, ordered the compilation of these written and oral traditions into a single, standardized text. This compilation process was completed under the caliphate of Uthman ibn Affan (r. 644-656 CE), who ordered copies of the Quran to be distributed to different regions of the Islamic empire.
The Quran remains the primary source of guidance for Muslims, who believe it to be the final and complete revelation from God. Alongside the Quran, the Hadith (sayings and actions of Prophet Muhammad) serve as an important source of Islamic law and ethics.
The Five Pillars of Islam

The core practices of Islam are encapsulated in the Five Pillars, which are essential acts of worship and devotion for all Muslims:
- Shahada (Faith): The declaration of faith, stating that “There is no god but God, and Muhammad is the Messenger of God.” This affirmation of monotheism and Muhammad’s role as the final prophet is central to Islamic belief.
- Salah (Prayer): Muslims are required to perform five daily prayers facing the Kaaba in Mecca. These prayers serve as a constant reminder of the believer’s relationship with God.
- Zakat (Charity): Muslims are obligated to give a portion of their wealth (usually 2.5%) to those in need, reinforcing the importance of social justice and community support.
- Sawm (Fasting): During the month of Ramadan, Muslims fast from dawn to sunset, refraining from food, drink, and other physical needs. Fasting is a form of spiritual discipline and a means of empathizing with the less fortunate.
- Hajj (Pilgrimage): Muslims who are physically and financially able are required to make a pilgrimage to Mecca at least once in their lifetime. The Hajj is a powerful expression of the unity and equality of all Muslims before God.

The Significance of Islam in World History
The emergence of Islam and its rapid expansion had a profound impact on world history. By the 8th century, the Islamic empire had become one of the largest and most powerful in the world, encompassing a vast and diverse range of cultures, languages, and peoples.

The Spread of Islam Beyond the Arab World
Islam continued to spread beyond the boundaries of the Arab world, reaching regions such as Sub-Saharan Africa, Central Asia, and Southeast Asia. This spread was facilitated by trade, migration, and the efforts of missionaries known as Sufis, who played a key role in spreading Islam to new areas.
In Africa, Islam spread across the Sahara through trade routes, leading to the establishment of Islamic states such as the Mali Empire. In Southeast Asia, Islam was introduced by Muslim traders and missionaries, leading to the gradual conversion of local populations and the rise of Islamic sultanates.
Did you know…?

Historically, Islam was referred to as Mohammedanism in English, a term that has fallen out of use due to its misleading implication that Muhammad, rather than God, is the central figure in the religion.
Conclusion
The history and origin of Islam are deeply intertwined with the life of the Prophet Muhammad and the socio-political context of 7th-century Arabia. From its humble beginnings in the Arabian Peninsula, Islam rapidly expanded to become a major world religion, shaping the course of history and contributing to the development of global civilization.
Today, Islam continues to be a dynamic and diverse religious tradition, with a rich cultural and intellectual heritage that spans continents and centuries. The teachings of Islam, as embodied in the Quran and the example of Prophet Muhammad, continue to guide the lives of over a billion Muslims around the world.

Why is there absence of images of the Prophet Muhammad?

Image: “Muhammad at the Ka’ba” from the Siyer-i Nebi. Muhammad is shown with veiled face, c. 1595.
The absence of images of the Prophet Muhammad in Islam stems from the belief that visual representations could lead to idolatry, which is strictly forbidden in the religion. This practice ensures that the focus remains on the teachings of Islam rather than the physical appearance of the Prophet. To avoid any form of idol worship, Islamic tradition emphasizes the reverence of Muhammad’s words and actions (the Sunnah) rather than his image, promoting the idea that God alone is to be worshipped.
