Chapter on the Prayer of the One in Necessity

As for what was narrated by al-Husayn ibn Sa'id from Hammad ibn Isa from Shu'ayb from Abu Basir from Abu Abdillah عليه السلام, peace be upon him, who said: I asked Imam al-Sadiq عليه السلام about a man who falls unconscious during the day and then regains consciousness before sunset. Imam عليه السلام said: “He performs the Dhuhr and Asr prayers, and if he regains consciousness during the night before dawn, he makes up the night (Isha) prayers.”
