Prophet Muhammad (peace and blessings be upon him) performed ‘Umrah four times, all of them in Dhu’l-Qi’dah apart from the ‘Umrah which he performed with his Hajj.

The first revelation given to Prophet Muhammad (peace and blessings of Allah be upon him) occurred in the cave of Hira when the angel Jibril appeared and commanded him to "Read." The verses revealed were the first five from Surat Al-`Alaq [Quran 96: 1-5], marking the beginning of prophethood and the Quran.
