Arabic text
وَإِذَا مَآ أُنزِلَتۡ سُورَةٞ نَّظَرَ بَعۡضُهُمۡ إِلَىٰ بَعۡضٍ هَلۡ يَرَىٰكُم مِّنۡ أَحَدٖ ثُمَّ ٱنصَرَفُواْۚ صَرَفَ ٱللَّهُ قُلُوبَهُم بِأَنَّهُمۡ قَوۡمٞ لَّا يَفۡقَهُونَ
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.
