Al-Furqan 25:47

Wahuwa allathee jaAAala lakumuallayla libasan wannawma subatan wajaAAalaannahara nushoora

And it is He who has made the night for you as clothing and sleep [a means for] rest and has made the day a resurrection.

He is the One who has made the night an apparel for you, and the sleep a means of rest, and has made the day a means of revival.
