39:5He created the heavens and the earth with reason. He wraps the night around the day, and He wraps the day around the night. And He regulates the sun and the moon, each running along a specific course. He is indeed the Almighty, the Forgiver.

39:9Is he who worships devoutly during the watches of the night, prostrating himself and standing up, mindful of the Hereafter, and placing his hope in the mercy of his Lord? Say, “Are those who know and those who do not know equal?” Only those possessed of reason will remember.
