أَلَمْ يَرَوْاْ أَنَّا جَعَلْنَا ٱلَّيْلَ لِيَسْكُنُواْ فِيهِ وَٱلنَّهَارَ مُبْصِرًاۚ إِنَّ فِى ذَٲلِكَ لَأَيَـٰتٍ لِّقَوْمٍ يُؤْمِنُونَ ٨٦
Have they not seen how We have appointed the night that they may rest therein, and the day sight-giving? Lo! therein verily are portents for a people who believe.
