Ar-Rum 30:23

وَمِنْ ءَايَـٰتِهِۦ مَنَامُكُم بِٱلَّيْلِ وَٱلنَّهَارِ وَٱبْتِغَآؤُكُم مِّن فَضْلِهِۦٓ ۚ إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ لِّقَوْمٍ يَسْمَعُونَ

Wamin āyātihi manāmukum bi-al-layli wal-nahāri wa-ib'tighāukum min faḍlihi inna fī dhālika laāyātin liqawmin yasmaʿūna

And of His signs is your sleep by night and day and your seeking of His bounty. Indeed in that are signs for a people who listen.
