Prophet Jonah - 10:67
He has made the night favorable for you to rest and the day light. In this are proofs for a people who listen.
What is the lesson in the alternation of night and day?

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?"

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.
