Yunus - 10:67

هُوَ الَّذِي جَعَلَ لَكُمُ اللَّيْلَ لِتَسْكُنُواْ فِيهِ وَالنَّهَارَ مُبْصِرًا إِنَّ فِي ذَلِكَ لآيَاتٍ لِّقَوْمٍ يَسْمَعُونَ
[10:67]
He it is Who made for you the night that you might rest in it, and the day giving light; most surely there are signs in it for a people who would hear.
He it is That hath made you the night that ye may rest therein, and the day to make things visible (to you). Verily in this are signs for those who listen (to His Message).
He it is Who hath appointed for you the night that ye should rest therein and the day giving sight. Lo! herein verily are portents for a folk that heed.
