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

أَلَمْ تَرَ كَيْفَ ضَرَبَ ٱللَّهُ مَثَلًا كَلِمَةً طَيِّبَةً كَشَجَرَةٍ طَيِّبَةٍ أَصْلُهَا ثَابِتٌ وَفَرْعُهَا فِى ٱلسَّمَآءِ

Have you not considered how Allāh presents an example, [making] a good word like a good tree, whose root is firmly fixed and its branches [high] in the sky?

Ibrahim 24

إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ لِّلْمُتَوَسِّمِينَ

Indeed in that are signs for those who discern.

Al-Hijr 75

وَلَقَد تَّرَكْنَا مِنْهَآ ءَايَةًۢ بَيِّنَةً لِّقَوْمٍ يَعْقِلُونَ

And We have certainly left of it a sign as clear evidence for a people who use reason.

Al-Ankabut 35

تَبْصِرَةً وَذِكْرَىٰ لِكُلِّ عَبْدٍ مُّنِيبٍ

Giving insight and a reminder for every servant who turns [to Allāh].

Qaf 8
