﴿ يُقَلِّبُ ٱللَّهُ ٱلَّيْلَ وَٱلنَّهَارَ ۚ إِنَّ فِى ذَٰلِكَ لَعِبْرَةًۭ لِّأُو۟لِى ٱلْأَبْصَٰرِ ﴾

“It is God who causes night and day to alter­nate: in this [too], behold, there is surely a lesson for all who have eyes to see!”

(Allah causeth the revolution of the day and the night) He takes away the night and brings in its stead the day and takes away the day and brings in its stead the night; this is what is meant by their revolution. (Lo! Herein) in the alternation of day and night which I have mentioned (is indeed a lesson) a sign (for those who see) in relation to matters of religion; it is also said that this means: those who see with their eyes.
