وَمِن رَّحْمَتِهِ جَعَلَ لَكُمُ اللَّيْلَ وَالنَّهَارَ لِتَسْكُنُوا فِيهِ وَلِتَبْتَغُوا مِن فَضْلِهِ وَلَعَلَّكُمْ تَشْكُرُونَ (73)
(28:73) It is His Mercy that He has made the night and the day for you so that you may have rest (in the night) and seek your Lord's bounty (in the day); maybe that you are grateful.
