The word(s) "sleeping" appears 4 time(s) in 4 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) 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.

(2) 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.

(3) 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.

(4) Then there encompassed it a visitation from your Lord while they were sleeping.
