Islam, as a distinct religion with the mission of the Prophet Muhammad, is generally understood to have begun in Mecca around 610 CE, when he received his first revelation.

Quick Scoop: Core Answer

Most historians and Muslim tradition agree on a key starting point:

  • Around 610 CE: Muhammad receives his first revelation from the Angel Jibril (Gabriel) in a cave on Mount Hira near Mecca; this is widely treated as the beginning of Islam as a religious movement.
  • 622 CE: Muhammad and his followers migrate from Mecca to Medina (the Hijra); this is so important that it marks year 1 of the Islamic calendar.

In short: Islam begins as a public, historical religion in early 7th‑century Arabia, with roots that Muslims see as going back to earlier prophets like Abraham.

Brief timeline (very short)

  • 570 CE: Birth of Muhammad in Mecca.
  • 610 CE: First revelation on Mount Hira → start of Muhammad’s prophetic mission and the beginning of Islam.
  • 622 CE: Hijra to Medina; Islamic calendar starts here.
  • 632 CE: Death of Muhammad; by this time most of Arabia follows Islam, and the religion soon spreads far beyond.

Two perspectives on “when did Islam begin?”

  • Historical perspective:
    • Focuses on when Islam appears as a recognizable, organized religion: early 7th century CE, beginning with Muhammad’s revelations in Mecca.
  • Muslim theological perspective:
    • Sees Islam as the continuation and restoration of the original monotheistic faith of earlier prophets (like Adam, Noah, Abraham, Moses, Jesus), with “Islam” meaning submission to God.
* In this view, the 7th‑century events are the final and complete revelation rather than the absolute start of God’s guidance.

Tiny FAQ

  • Why 610 CE and not Muhammad’s birth (570)?
    Because Islam is understood to begin with revelation, not simply with the birth of its prophet.
  • Why does the calendar start at 622, not 610?
    The Hijra created the first organized Muslim community and state in Medina, a turning point significant enough to become year one.
