24:44
يُقَلِّبُ ٱللَّهُ ٱلَّيْلَ وَٱلنَّهَارَ ۚ إِنَّ فِى ذَٰلِكَ لَعِبْرَةً لِّأُو۟لِى ٱلْأَبْصَـٰرِ
yuqallibu l-lahu al-layla wal-nahāra inna fī dhālika laʿib'ratan li-ulī l-abṣāri
God alternates night and day- there truly is a lesson in [all] this for those who have eyes to see-
Allâh causes the night and the day to succeed each other (i.e. if the day is gone, the night comes, and if the night is gone, the day comes, and so on). Truly, in this is indeed a lesson for those who have insight.
