وَاِذَا مَاۤ اُنۡزِلَتۡ سُوۡرَةٌ نَّظَرَ بَعۡضُهُمۡ اِلٰى بَعۡضٍؕ هَلۡ يَرٰٮكُمۡ مِّنۡ اَحَدٍ ثُمَّ انصَرَفُوۡا ؕ صَرَفَ اللّٰهُ قُلُوۡبَهُمۡ بِاَنَّهُمۡ قَوۡمٌ لَّا يَفۡقَهُوۡنَ
Whenever a Sura (chapter) is revealed, they look at one another (and inquire through body language:) ‘Is there anyone watching you?’ Then they turn away. Allah has turned their hearts away because they are the ones who lack understanding.
