The word(s) "sleep" appears 12 time(s) in 12 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Allah is He besides Whom there is no god, the Everliving, the Self-subsisting by Whom all subsist; slumber does not overtake Him nor sleep; whatever is in the heavens and whatever is in the earth is His; who is he that can intercede with Him but by His permission? He knows what is before them and what is behind them, and they cannot comprehend anything out of His knowledge except what He pleases, His knowledge extends over the heavens and the earth, and the preservation of them both tires Him not, and He is the Most High, the Great.

(2) Men are the maintainers of women because Allah has made some of them to excel others and because they spend out of their property; the good women are therefore obedient, guarding the unseen as Allah has guarded; and (as to) those on whose part you fear desertion, admonish them, and leave them alone in the sleeping-places and beat them; then if they obey you, do not seek a way against them; surely Allah is High, Great.

(3) And He it is Who takes your souls at night (in sleep), and He knows what you acquire in the day, then He raises you up therein that an appointed term may be fulfilled; then to Him is your return, then He will inform you of what you were doing.

(4) What! do the people of the towns then feel secure from Our punishment coming to them by night while they sleep?

(5) And you might think them awake while they were asleep and We turned them about to the right and to the left, while their dog (lay) outstretching its paws at the entrance; if you looked at them you would certainly turn back from them in flight, and you would certainly be filled with awe because of them.

(6) And He it is Who made the night a covering for you, and the sleep a rest, and He made the day to rise up again.

(7) And one of His signs is your sleeping and your seeking of His grace by night and (by) day; most surely there are signs in this for a people who would hear.

(8) They shall say: O woe to us! who has raised us up from our sleeping-place? This is what the Beneficent Allah promised and the apostles told the truth.

(9) Allah takes the souls at the time of their death, and those that die not during their sleep; then He withholds those on whom He has passed the decree of death and sends the others back till an appointed term; most surely there are signs in this for a people who reflect.

(10) They used to sleep but little in the night.
