وَإِذَا مَا أُنزِلَتْ سُورَةٌ نَّظَرَ بَعْضُهُمْ إِلَى بَعْضٍ هَلْ يَرَاكُم مِّنْ أَحَدٍ ثُمَّ انصَرَفُواْ صَرَفَ اللّهُ قُلُوبَهُم بِأَنَّهُمْ قَوْمٌ لاَّ يَفْقَهُون
[9:127]
And whenever a chapter is revealed, they cast glances at one another: Does any one see you? Then they turn away: Allah has turned away their hearts because they are a people who do not understand.
Whenever there cometh down a Sura, they look at each other, (saying), "Doth anyone see you?" Then they turn aside: Allah hath turned their hearts (from the light); for they are a people that understand not.
And whenever a surah is revealed, they look one at another (as who should say): Doth anybody see you? Then they turn away. Allah turneth away their hearts because they are a folk who understand not.
