The Family Of Imran - 3:27 You bring the night into the day, and You bring the day into the night. You bring forth the living from the dead and the dead from the living. And You provide for whomsoever You will.
What is the lesson in the alternation of night and day?
The Stories/28:71 "Say, "What would you say if Allah made the night perpetual upon you until the Day of Resurrection? Which God besides Allah can bring you any light? Do you not hear?"
The Stories/28:72 "Say, "What would you say if Allah made the day continuous upon you until the Day of Resurrection? Which God besides Allah can bring you the night of rest? Do you not see?"
The Stories/28:73 It is of His Mercy that He arranged the night and the day, that you may rest in the one and seek His Blessings in the other. Perhaps you will be grateful.

The Believers/23:80 It is He who resurrects and slays; to Him is the change of night and day. Do you not use your intellect?

The Ants/27:86 Have they not seen that We have made the night favorable for their rest and the day bright? Surely there are signs in this for a people who believe.

The Forgiver/40:61 It is Allah Who created the night for you to rest and made the day bright. Allah is gracious to the people, but most of the people do not give thanks.
