Jabal al-Nour is located in the Hejaz region of Saudi Arabia, just outside of Makkah. Jabal Al-Nour translates to “Mountain of Light.” Prophet Muhammad (peace and blessings be upon him) received his first revelation from Allah (the Glorified and Exalted) through Angel Jibreel (Gabriel) in the Hira cave which is on this mountain. Prophet Muhammad (peace be upon him) used to climb this mountain often even before receiving his fist revelation from Allah (the Glorified and Exalted).
The cave of Hira’ is a cave in which the Prophet (peace and blessings of Allah be upon him) used to worship Allah for several nights before his Prophethood began and the Revelation came to him when he was in this cave, but the Prophet (peace and blessings of Allah be upon him) did not go back to it after that, and the Sahaabah did not visit it.
