Qur'an, Ya Sin, Surah 36:36-40
Glory be to Him who created everything in pairs: plants, human beings, and even entities they have no knowledge of. Of the many, one sign is the night. We strip it of the light of day, and abject darkness surrounds everything. The sun hastens to its resting place, its course determined by the Mighty, the All-Knowing Lord. Also ordained by the Almighty Lord are the phases of the moon, which decreases daily until it looks like a bent and shriveled palm stalk. Neither can the sun overtake the moon, nor night outstrip the day. Both float in orbits of their own.
