Islam began as a public religious movement in the early 7th century CE in Mecca, in the Arabian Peninsula. According to the traditional Islamic account, Prophet Muhammad ﷺ received the first revelation of the Qur’an through the Angel Jibril (Gabriel) in 610 CE, while he was in the Cave of Hira near Mecca.

So, if you are asking “when did Islam start?”, “when was Islam founded?”, or “what year did Islam begin?”, the simplest historical answer is:

However, there is an important distinction. Muslims do not generally understand Islam as a religion “invented” or “created” by Muhammad ﷺ in 610 CE. Islamic belief teaches that submission to the one God was also the religion preached by earlier prophets, including Adam, Noah (Nuh), Abraham (Ibrahim), Moses (Musa), and Jesus (Isa), peace be upon them all.

The year 610 CE therefore refers specifically to the beginning of Prophet Muhammad’s ﷺ revelation and prophetic mission. In scholarly and curatorial records exploring the birth and early history of Islam, historians similarly emphasize this pivotal transition in seventh-century Arabia.

Another crucial date is 622 CE, when Muhammad ﷺ and his followers migrated from Mecca to Medina in an event known as the Hijrah. The Hijrah became so important in Islamic history that 622 CE marks the starting point of the Islamic Hijri calendar.

Quick Answer: When and Where Did Islam Begin?

---

Where Did Islam Originate?

The origin of Islam as the final prophetic mission is associated with Mecca, an ancient city in western Arabia.

Mecca was already an important religious and commercial center before Muhammad’s ﷺ prophetic mission. At its center stood the Kaaba, which is today Islam's holiest sanctuary and the direction (Qibla) toward which Muslims around the world pray.

Islamic tradition connects the Kaaba with Prophet Ibrahim (Abraham) and his son Ismail (Ishmael), peace be upon them.

The Qur’an says:

“Indeed, the first House [of worship] established for mankind was that at Makkah—blessed and a guidance for the worlds.”

— Qur’an 3:96

Therefore, questions such as “where did Islam start?”, “where did Islam begin?”, “where was Islam founded?”, “where did Islam come from?”, “what is the country of origin of Islam?”, and “where did the Islamic religion originate?” all point historically to the Arabian Peninsula, particularly Mecca in the Hijaz.

In modern geographical terms, Mecca is located in Saudi Arabia. It is worth remembering, however, that the modern Kingdom of Saudi Arabia did not exist in the 7th century. Saying that Islam originated in “Saudi Arabia” is useful for modern geographic identification, but historically the more accurate description is Mecca in the Hijaz region of western Arabia.

When Was Islam Founded?

The question “when was Islam founded?” requires a little clarification because “founded” can mean different things.

From a conventional historical perspective, the beginning of Islam is generally associated with approximately 610 CE, when Muhammad ﷺ began receiving revelations.

From the Islamic theological perspective, however, Islam was not a completely new religion created in the seventh century.

The Qur’an presents Muhammad ﷺ as part of a much longer succession of prophets who called people to worship the one God.

“Say, ‘We believe in Allah and what has been revealed to us and what was revealed to Abraham, Ishmael, Isaac, Jacob, and the Descendants, and what was given to Moses and Jesus and what was given to the prophets from their Lord.’”

— Qur’an 2:136

Thus, there are two useful ways of answering the question:

• Historical answer: Islam emerged in Arabia in the 7th century CE, with Muhammad’s ﷺ first revelation traditionally dated to 610 CE.
• Islamic theological answer: The essential message of Islam—submission to and worship of the one God—is understood as the message taught by all of God's prophets, while Muhammad ﷺ received the final revelation beginning in 610 CE.

This distinction is important when answering searches such as “when was Islam created?”, “when was Islam invented?”, “Islam creation,” or “who invented Islam.”

What Does the Word “Islam” Mean?

The Arabic word Islam (إسلام) is associated with submission or surrender to God and derives from the root s-l-m, which also carries the concept of peace and wholeness.

A person who follows Islam is called a Muslim (مسلم)—one who surrenders and submits to Allah's will.

Islam centers on belief in one God—Allah, the Arabic word for God—and accepting His guidance.

Consequently, “Islam” should not simply be understood as the name of an ethnic group, country, or culture. Muslims come from many different ethnicities, nationalities, and linguistic backgrounds across every continent.

---

Who Founded Islam?

Search engines frequently receive questions such as who founded Islam?, who started Islam?, who created Islam?, and who is the founder of the Muslim religion?

In conventional historical writing, Prophet Muhammad ﷺ is often described as the founder of Islam because the identifiable historical Muslim community developed through his prophetic mission in seventh-century Arabia.

From the Islamic perspective, however, describing Muhammad ﷺ as the person who “invented” Islam is inaccurate.

Muslims believe that Allah is the source of the religion and that Muhammad ﷺ was His prophet and messenger. Muhammad ﷺ conveyed the revelation he received; he did not claim to be its divine author.

The Qur’an describes him as:

“Muhammad is not the father of any of your men, but is the Messenger of Allah and the seal of the prophets.”

— Qur’an 33:40

Therefore, a more precise answer is:

---

Who Was Prophet Muhammad ﷺ?

Prophet Muhammad ﷺ was born in Mecca around 570 CE into the Banu Hashim clan of the Quraysh tribe.

Before receiving revelation, Islamic biographical tradition records that he was widely known among the Meccans as Al-Amin (the Trustworthy) and Al-Sadiq (the Truthful) for his integrity and honesty.

As he approached the age of forty, Muhammad ﷺ increasingly spent periods in quiet contemplation and prayer away from the materialism and idol worship of Meccan society.

One location associated particularly strongly with this period was the Cave of Hira, situated in Mount Jabal al-Nur outside Mecca. It was there that his prophetic mission began.

How Did Islam Begin?

The answer to “how did Islam start?” begins with the first revelation of the Qur’an.

Around 610 CE, while Muhammad ﷺ was in the Cave of Hira during the month of Ramadan, the Angel Jibril (Gabriel) appeared to him with divine revelation from Allah.

The opening verses traditionally associated with this first revelation are from Surah Al-'Alaq:

“Read in the name of your Lord who created—created humans from a clinging clot. Read! And your Lord is the Most Generous—Who taught by the pen—taught man that which he knew not.”

— Qur’an 96:1–5

This transformative encounter marked the inception of approximately 23 years of Qur’anic revelation. Preserved historical manuscripts and artifacts documenting early Qur’anic revelation provide tangible evidence of how these sacred verses were transcribed and memorized by the earliest generation of Muslims.

Revelation continued during Muhammad’s ﷺ years in Mecca and later in Medina until the completion of the message near the end of his life.

The Beginning of Islam in Mecca

The earliest phase of Islamic history is known as the Meccan period (610–622 CE).

Muhammad ﷺ initially shared the message privately with his closest family and friends. According to traditional Islamic accounts, among the earliest believers were:

• Khadijah bint Khuwaylid (RA): Muhammad’s ﷺ beloved wife and the very first person to believe in his prophethood.
• Ali ibn Abi Talib (RA): Muhammad’s ﷺ young cousin, who was the first youth to accept Islam.
• Abu Bakr al-Siddiq (RA): Muhammad’s ﷺ close and noble friend, who brought many prominent companions into Islam.
• Zayd ibn Harithah (RA): Muhammad’s ﷺ adopted son and loyal companion.
• Bilal ibn Rabah (RA): An early African convert who demonstrated unwavering faith despite severe torture, later becoming the first Mu’adhin (caller to prayer).

The central message was straightforward but revolutionary: worship Allah alone and reject all idols. Islam also emphasized moral accountability, justice for the oppressed, care for orphans and the poor, honest trade, and the certainty of the Day of Judgment.

Opposition and Persecution in Mecca

When public preaching commenced around 613 CE, Muhammad’s ﷺ message faced fierce opposition from the ruling Quraysh aristocracy.

The message directly challenged Mecca's lucrative trade built around pagan pilgrimages and polytheism. As the Muslim community grew, early converts—particularly slaves and disadvantaged individuals—endured intense social boycotts, economic deprivation, physical torture, and assassination attempts.

Despite this harsh opposition, Muhammad ﷺ remained steadfast. In 615 CE, a group of vulnerable Muslims migrated across the Red Sea to Abyssinia (modern-day Ethiopia), where the righteous Christian King, the Negus (al-Najashi), granted them asylum and protection.

The Hijrah: Islam's Major Turning Point (622 CE)

In 622 CE, facing escalating plots against his life, Prophet Muhammad ﷺ and his companion Abu Bakr (RA) made the momentous migration from Mecca to Yathrib, an oasis city north of Mecca.

Yathrib was soon renamed Madinat al-Nabi (The City of the Prophet), known today simply as Medina.

This historic migration is known as the Hijrah. It represents far more than a relocation; it was the foundation of the first sovereign, self-governing Islamic community (Ummah) bound not by tribal lineage, but by shared faith, mutual brotherhood, and constitutional justice (the Constitution of Medina).

Did Islam Start in 610 or 622?

Both dates appear frequently in discussions regarding the origin of Islam, but they signify two distinct historical milestones:

---

Why Does the Islamic Calendar Begin in 622 Instead of 610?

Although divine revelation began in 610 CE, the Islamic calendar is dated from the Hijrah in 622 CE.

During the caliphate of Umar ibn al-Khattab (RA), the companions deliberated on establishing an official calendar. Rather than choosing the birth or death of the Prophet ﷺ, they unanimously chose the Hijrah because it represented the decisive transition from persecution to safety and established Islam as an organized society.

Years in this calendar are denoted as AH (Anno Hegirae — in the year of the Hijrah). Because the Islamic calendar is strictly lunar (approximately 354 days per year), Hijri years rotate through the Gregorian solar seasons.

The Medinan Period and the Growth of the Community

In Medina, Muhammad ﷺ acted as both a prophet of God and a community leader. The Medinan revelations established comprehensive legal, civic, economic, and ethical frameworks:

• Prescriptions for daily prayers, the institution of Friday Jummah, and the fast of Ramadan.
• Systematic laws governing Zakat (obligatory charity), inheritance, marriage, and civil contracts.
• Principles of ethical warfare, treaties of peace, and diplomatic relations with neighboring tribes and empires.
• Establishment of the Prophet's Mosque (Al-Masjid an-Nabawi) as the spiritual and communal center.

The Conquest of Mecca (630 CE) and the Completion of Prophethood

In 630 CE (8 AH), following the violation of the Treaty of Hudaybiyyah by the Quraysh, Muhammad ﷺ led an army of 10,000 Muslims into Mecca.

The city was taken peacefully with virtually no bloodshed. In an unprecedented act of magnanimity, the Prophet ﷺ declared a general amnesty for his former persecutors, saying: “Go, for you are free.”

He entered the Kaaba, shattered the 360 pagan idols surrounding it, and cleansed the sanctuary, returning it to the pure monotheistic worship of Allah established by Ibrahim (AS).

In 632 CE, Prophet Muhammad ﷺ performed the Farewell Pilgrimage (Hajjat al-Wada') and delivered his famous Farewell Sermon, emphasizing human equality, racial justice, the rights of women, and the sanctity of life and property. Shortly thereafter, in June 632 CE, he passed away in Medina at approximately 63 years of age.

Following the Prophet's ﷺ death, the Muslim community elected four successive leaders known in Sunni tradition as the Rashidun Caliphs:

Timeline of the Origin and Early History of Islam

---

What Is the Origin of the Islamic Religion?

The origin of the Islamic religion can be understood at two complementary levels:

Historically: The recognizable Islamic religious community emerged in seventh-century western Arabia, particularly in Mecca and Medina.

Theologically: Islam identifies itself with the primordial monotheistic tradition taught by all previous prophets. The Qur’an gives special attention to Prophet Ibrahim (Abraham), describing his devotion to pure monotheism:

“Abraham was neither a Jew nor a Christian; he submitted in all uprightness and was not a polytheist.”

— Qur’an 3:67

For Muslims, therefore, Islam's spiritual origin does not begin with the invention of a new God or a new concept of monotheism in the seventh century. Muhammad ﷺ is understood as restoring and completing the timeless call to worship the one Creator.

---

What Was the Central Message of Early Islam?

At the heart of Muhammad’s ﷺ preaching was Tawhid—the absolute, uncompromising oneness of God.

The Qur’an expresses this core theology succinctly in Surah Al-Ikhlas:

“Say, ‘He is Allah—One; Allah, the Eternal Refuge; He neither begets nor is born, nor is there to Him any equivalent.’”

— Surah Al-Ikhlas (Qur’an 112:1–4)

Early Islamic teaching also firmly established:

• Exclusive worship of Allah: Rejection of all idolatry, superstition, and human intermediaries.
• Moral accountability: Belief in the Resurrection, the Day of Judgment, and ultimate justice.
• Social equality & charity: Protection of widows, orphans, travelers, and the vulnerable.
• Devotional discipline: Sincere prayer (Salah), fasting (Sawm), and continuous remembrance of Allah (Dhikr).
