Sleep is presented here as one of Allah’s favours to man and a mercy for the distressed, while Allah Himself is overtaken by neither drowsiness nor sleep. The verses describe it as a form of death, during which Allah takes the souls, and recall that visions come during sleep and that calamities then strike harder.
Verses gathered from a topical index of the Quran, in Mushaf order; every verse is quoted in full.
Allāh takes the souls at the time of their death, and those that do not die [He takes] during their sleep. Then He keeps those for which He has decreed death and releases the others for a specified term. Indeed in that are signs for a people who give thought.
