The first revelation
The descent of Jibril upon the Prophet ﷺ in the cave of Hira with the opening verses of surat al-Alaq, on the night of Monday 21 Ramadan in the book's preferred reckoning, corresponding to 10 August 610 CE, when the Prophet was forty lunar years, six months and twelve days old. The Encyclopaedia of Islam summarises the Muslim accounts of this first revelation and of the experience of wahy, and sets beside them the academic view that the traditional stories of a first revelation are doubtful.
