وَإِذَا مَا أُنْزِلَتْ سُورَةٌ نَظَرَ بَعْضُهُمْ إِلَىٰ بَعْضٍ هَلْ يَرَاكُمْ مِنْ أَحَدٍ ثُمَّ انْصَرَفُوا ۚ صَرَفَ اللَّهُ قُلُوبَهُمْ بِأَنَّهُمْ قَوْمٌ لَا يَفْقَهُونَ 127
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.
