31:29Have you not seen how God merges the night into the day, and merges the day into the night? That He subjected the sun and the moon, each running for a stated term? And that God is Cognizant of everything you do?

31:32When waves, like canopies, cover them, they call upon God, devoting their religion to Him. But when He has delivered them to dry land, some of them waver. No one renounces Our revelations except the treacherous blasphemer.
