أَلَمْ تَرَ أَنَّ ٱللَّهَ يُولِجُ ٱلَّيْلَ فِى ٱلنَّهَارِ وَيُولِجُ ٱلنَّهَارَ فِى ٱلَّيْلِ وَسَخَّرَ ٱلشَّمْسَ وَٱلْقَمَرَ كُلٌّ يَجْرِىٓ إِلَىٰٓ أَجَلٍ مُّسَمًّى وَأَنَّ ٱللَّهَ بِمَا تَعْمَلُونَ خَبِيرٌ

[Prophet], do you not see that God causes the night to merge into day and the day to merge into night; that He has subjected the sun and the moon, each to run its course for a stated term; that He is aware of everything you [people] do?
See you not (O Muhammad صلى الله عليه وسلم) that Allâh merges the night into the day (i.e. the decrease in the hours of the night are added to the hours of the day), and merges the day into the night (i.e. the decrease in the hours of day are added to the hours of night), and has subjected the sun and the moon, each running its course for a term appointed; and that Allâh is All-Aware of what you do.
