Jabal an-Nour (Arabic: جَـبَـل ٱلـنُّـوْر, romanized: Jabal an-Nūr, lit. 'Mountain of the Light' or 'Hill of the Illumination') is a mountain near Mecca in the Hejazi region of Saudi Arabia.[1] The mountain houses the famed Grotto/Cave of Hira (Arabic: غَـار حِـرَاء, romanized: Ġār Ḥirāʾ). The mountain and its cave hold tremendous significance for Muslims throughout the world, as the Islamic Nabī (Prophet) Muhammad is said to have spent a great deal of time in the cave meditating, and it is widely believed that it was here that he received his first revelation, which consisted of the first five ayats of Surah Al-Alaq from the angel Jibrā’īl (as is pronounced in certain Quran recitation schools and some Arab tribes; also known as Gabriel).[2] It is one of the most popular tourist attractions in Makkah. The mountain itself is barely 640 m (2,100 ft) tall; nonetheless one to two hours are needed to make the strenuous hike to the cave. There are 1750 steps to the top, which can take anywhere between 25 minutes to 1hr 30 minutes.
