إِنَّ فِي اخْتِلاَفِ اللَّيْلِ وَالنَّهَارِ وَمَا خَلَقَ اللّهُ فِي السَّمَاوَاتِ وَالأَرْضِ لآيَاتٍ لِّقَوْمٍ يَتَّقُونَ
[10:6]
Most surely in the variation of the night and the day, and what Allah has created in the heavens and the earth, there are signs for a people who guard (against evil).
Verily, in the alternation of the night and the day, and in all that Allah hath created, in the heavens and the earth, are signs for those who fear Him.
Lo! in the difference of day and night and all that Allah hath created in the heavens and the earth are portents, verily, for folk who ward off (evil).
