Qur'ān 30:23 · Ar-Rum (الروم)

وَمِنْ ءَايَـٰتِهِۦ مَنَامُكُم بِٱلَّيْلِ وَٱلنَّهَارِ وَٱبْتِغَآؤُكُم مِّن فَضْلِهِۦٓ ۚ إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍۢ لِّقَوْمٍۢ يَسْمَعُونَ

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.
