Therefore We covered up their (sense of) hearing (causing them, to go in deep sleep) in the Cave for a number of years.

Then We raised them up (from their sleep), that We might test which of the two parties was best at calculating the time period that they had tarried.

And it is He Who makes the night a covering for you, and the sleep (as) repose, and makes the day Nushur (i.e. getting up and going about here and there for daily work, etc. after one's sleep at night or like resurrection after one's death).

They used to sleep but little by night [invoking their Lord (Allah) and praying, with fear and hope].

And have made your sleep as a thing for rest.
