﴿ 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 maketh the sun and the moon, constant in their courses) until the Day of Judgement, (to be of service unto you) subservient to you, (and hath made of service) and made subservient (unto you the night and the day) which come and go.
