Al-Isra is the Prophet’s ﷺ night journey from the Sacred Mosque in Mecca to al-Aqsa Mosque (Quran 17:1); al-Mi’raj is his ascension through the heavens (53:13-18). It was during this night that the five daily prayers were prescribed (Bukhari 349, Muslim 162).

Its date is not established with certainty: the night of the 27th of Rajab is the most widespread, but scholars have mentioned other dates, and Ibn Hajar reports more than ten opinions. No act of worship specific to this night has been reported from the Prophet ﷺ.

Isra and Mi’raj falls on 27 Rajab of every Hijri year. As the Hijri calendar is lunar, its Gregorian date moves about 11 days earlier each year.
