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