Jabal al-Hira is a mountain which lies about two miles from the Ka’bah. Near the top is a small cave known as the Cave of Hira. It was here that the Prophet Muhammad (ﷺ) received the first revelations of the Holy Quran during the month of Ramadhan in 610 CE. The mountain is also known as Jabal al-Noor (the Mountain of Light) and Jabal al-Islam (the Mountain of Islam).
The Quran tells us that the first revelation descended in Ramadan on the ‘Night of Power’.“The month of Ramadan is the month in which the Quran was revealed.” [2:185]
“We have indeed revealed this message during the Night of Power.” [97:1]
The entire Quran was revealed over a period of approximately 22 years, 5 months and 14 days.
