وَإِذَا مَآ أُنزِلَتْ سُورَةٌ نَّظَرَ بَعْضُهُمْ إِلَىٰ بَعْضٍ هَلْ يَرَىٰكُم مِّنْ أَحَدٍ ثُمَّ ٱنصَرَفُوا۟ ۚ صَرَفَ ٱللَّهُ قُلُوبَهُم بِأَنَّهُمْ قَوْمٌ لَّا يَفْقَهُونَ

And whenever a sūrah is revealed, they look at each other, [as if saying], "Does anyone see you?" and then they dismiss themselves. Allāh has dismissed their hearts because they are a people who do not understand.

At-Tawbah 127

يُقَلِّبُ ٱللَّهُ ٱلَّيْلَ وَٱلنَّهَارَ ۚ إِنَّ فِى ذَٰلِكَ لَعِبْرَةً لِّأُو۟لِى ٱلْأَبْصَـٰرِ

Allāh alternates the night and the day. Indeed in that is a lesson for those who have vision.

An-Nur 44

فَلَآ أُقْسِمُ بِٱلشَّفَقِ

So I swear by the twilight glow
