Night and day as signs

هُوَ ٱلَّذِى جَعَلَ لَكُمُ ٱلَّيْلَ لِتَسْكُنُوا۟ فِيهِ وَٱلنَّهَارَ مُبْصِرًا ۚ إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ لِّقَوْمٍ يَسْمَعُونَ

It is He who made for you the night to rest therein and the day, giving sight. Indeed in that are signs for a people who listen.

وَٱلَّيْلِ إِذْ أَدْبَرَ

And [by] the night when it departs.
