Al-Qasas 28:73

وَمِن رَّحۡمَتِهِۦ جَعَلَ لَكُمُ ٱلَّيۡلَ وَٱلنَّهَارَ لِتَسۡكُنُواْ فِيهِ وَلِتَبۡتَغُواْ مِن فَضۡلِهِۦ وَلَعَلَّكُمۡ تَشۡكُرُونَ 73

And out of His mercy He made for you the night and the day that you may rest therein and [by day] seek from His bounty and [that] perhaps you will be grateful
