ٱللَّهُ ٱلَّذِى جَعَلَ لَكُمُ ٱلَّيْلَ لِتَسْكُنُوا۟ فِيهِ وَٱلنَّهَارَ مُبْصِرًا ۚ إِنَّ ٱللَّهَ لَذُو فَضْلٍ عَلَى ٱلنَّاسِ وَلَٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَشْكُرُونَ
Allah it is Who hath appointed for you night that ye may rest therein, and day for seeing. Lo! Allah is a Lord of bounty for mankind, yet most of mankind give not thanks.
