وَمِنْ ءَايَٰتِهِۦ مَنَامُكُم بِٱلَّيْلِ وَٱلنَّهَارِ وَٱبْتِغَآؤُكُم مِّن فَضْلِهِۦٓ ۚ إِنَّ فِى ذَٰلِكَ لَءَايَٰتٍ لِّقَوْمٍ يَسْمَعُونَ
10:68; 27:87; 28:74.
Commentary:
The alternation of day and night provides one more evidence of the wisdom and intelligence underlying the creation of the universe. Normally man works by day, and needs rest at night to replenish his tired and jaded faculties.
