THE 1st REVELATION…
Revelation was an event described in Islam as taking place in 610 AD, during which ProphetMuhammad was visited by the archangel Jibrīl (i.e. Gabrael) who revealed to him the beginnings of what would later become the Quran. The event took place in a cave called Hira, located on the mountain Jabal an-Nour, near Mecca. As for the exact date of this event, it has been calculated to Monday the 21st of Ramadan at night, (i.e. August 10, 610 C.E. – when the Prophet was 40 lunar years, 6 months and 12 days of age or 39 Gregorian years, 3 months and 22 days).
According to biographies of Muhammad,[which?] while on retreat in a mountain cave near Mecca (the cave of Hira), Gabriel appears before him and commands him to recite the first 5 lines of chapter 96 of the Quran. Muhammad’s experience is mentioned in Surah 53:4–9 of the Qur’an.
