وَإِذَا مَآ أُنزِلَتْ سُورَةٌ نَّظَرَ بَعْضُهُمْ إِلَىٰ بَعْضٍ هَلْ يَرَىٰكُم مِّنْ أَحَدٍ ثُمَّ ٱنصَرَفُوا۟ ۚ صَرَفَ ٱللَّهُ قُلُوبَهُم بِأَنَّهُمْ قَوْمٌ لَّا يَفْقَهُونَ
wa-idhā mā unzilat sūratun naẓara baʿḍuhum ilā baʿḍin hal yarākum min aḥadin thumma inṣarafū ṣarafa l-lahu qulūbahum bi-annahum qawmun lā yafqahūna
Whenever a sura is revealed, they look at each other and say, ‘Is anyone watching you?’ and then they turn away- God has turned their hearts away because they are people who do not use their reason.
And whenever there comes down a Sûrah (chapter from the Qur’ân), they look at one another (saying): "Does any one see you?" Then they turn away. Allâh has turned their hearts (from the light) because they are a people that understand not.
