Al-Qasas 73

وَمِن رَّحْمَتِهِۦ جَعَلَ لَكُمُ ٱلَّيْلَ وَٱلنَّهَارَ لِتَسْكُنُوا۟ فِيهِ وَلِتَبْتَغُوا۟ مِن فَضْلِهِۦ وَلَعَلَّكُمْ تَشْكُرُونَ ﴿٧٣﴾

Wamin rahmatihi jaAAala lakumu allayla waalnnahara litaskunoo feehi walitabtaghoo min fadlihi walaAAallakum tashkuroona

It is out of His Mercy that He has put for you night and day, that you may rest therein (i.e. during the night) and that you may seek of His Bounty (i.e. during the day), and in order that you may be grateful. The Noble Quran
