وَإِذَا مَآ أُنزِلَتۡ سُورَةٞ نَّظَرَ بَعۡضُهُمۡ إِلَىٰ بَعۡضٍ هَلۡ يَرَىٰكُم مِّنۡ أَحَدٖ ثُمَّ ٱنصَرَفُواْۚ صَرَفَ ٱللَّهُ قُلُوبَهُم بِأَنَّهُمۡ قَوۡمٞ لَّا يَفۡقَهُونَ
Wa izaa maaa unzilat Sooratun nazara ba'duhum ilaa ba'din hal yaraakum min ahadin summman sarafoo; sarafal laahu quloobahum bi annahum qawmul laa yafqahoon
English Translation
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
