Verses 5-6 of Chapter 39:

He has created the heavens and the earth with the truth. He it is Who wraps the night about the day and the day about the night. He has so subjected the sun and the moon that each is moving till an appointed time. Note it well: He is the All-Mighty, the All-Forgiving. It is He Who created you from a single being, then from that being He created its mate, and it is He Who created for you eight heads of cattle, male and female. He shapes you in your mothers' wombs, giving you one form after the other, under three dark veils. This same Allah (Whose works are these) is your Lord Sovereignty is His. There is no god but He. Whence are you, then, being turned away?
