Al-An'am 6:96

Faliqu al-isbahiwajaAAala allayla sakanan washshamsa walqamara husbananthalika taqdeeru alAAazeezi alAAaleem

[He is] the cleaver of daybreak and has made the night for rest and the sun and moon for calculation. That is the determination of the Exalted in Might, the Knowing.

(He is) the One who causes the dawn to break. He has made the night for rest, and the sun and the moon for reckoning. This is a measure set by the All-Mighty, the All-Knowing.
