"He created the heavens and the earth for the truth," meaning: for resurrection, reckoning, Paradise, and Hell. "He wraps the night over the day and wraps the day over the night," meaning: each of them takes from the other. "And He has subjected the sun and the moon, each running for a specified term," meaning: until the Day of Resurrection. "Unquestionably, He is the Exalted in Might, the Perpetual Forgiver" to whoever believes.
