73وَمِن رَحمَتِهِ جَعَلَ لَكُمُ اللَّيلَ وَالنَّهارَ لِتَسكُنوا فيهِ وَلِتَبتَغوا مِن فَضلِهِ وَلَعَلَّكُم تَشكُرونَ(Irfan-ul-Quran)And it is out of His Mercy that He has made night and day for you so that at night you may take rest and (during the day) you may seek His Bounty (sustenance) and so that you may become grateful.
