﴿ وَسَخَّرَ لَكُمُ ٱلشَّمْسَ وَٱلْقَمَرَ دَآئِبَيْنِ ۖ وَسَخَّرَ لَكُمُ ٱلَّيْلَ وَٱلنَّهَارَ ﴾

“and has made the sun and the moon, both of them constant upon their courses, subservient [to His laws, so that they be of use] to you; and has made the night and the day subservient [to His laws, so that they be of use] to you.”

And He has disposed for you the sun and the moon constant moving in their courses without pause; and He has disposed for you the night that you may rest therein and the day that you may seek of His bounty therein.
