On Jabal al-Nour is Ghar Hira (Cave of Hira). It is a small cave about 3.5 meters long and a little over 1.5 meters wide.
It’s in this cave that Prophet Muhammad (may the blessings and peace of Allah be upon him) found the solitude he needed to meditate. The Prophet (may the blessings and peace of Allah be upon him) would come here to find solitude.
In the year 610, when Prophet Muhammad (may the blessings and peace of Allah be upon him) was 40 years old, he received his first divine revelation from Allah (the Glorified and Exalted) through Angel Jibreel.
When Angel Jibreel, appeared to him he said, Read! In the Name of your Lord, Who has created (all that exists), He has created man from a clot (a piece of thick coagulated blood), Read! And your Lord is the Most Generous, Who has taught (the writing) by the pen. He has taught man that which he knew not. Holy Quran (Al Alaq 96: 1-5).
