Surah At-Tawba, Verse 127
وَإِذَا مَآ أُنزِلَتْ سُورَةٌۭ نَّظَرَ بَعْضُهُمْ إِلَىٰ بَعْضٍ هَلْ يَرَىٰكُم مِّنْ أَحَدٍۢ ثُمَّ ٱنصَرَفُوا۟ ۚ صَرَفَ ٱللَّهُ قُلُوبَهُم بِأَنَّهُمْ قَوْمٌۭ لَّا يَفْقَهُونَ
Translation — Sahih International
And whenever a surah is revealed, they look at each other, [saying], "Does anyone see you?" and then they dismiss themselves. Allah has dismissed their hearts because they are a people who do not understand.
