﴿ وَإِذَا مَآ أُنزِلَتْ سُورَةٌۭ نَّظَرَ بَعْضُهُمْ إِلَىٰ بَعْضٍ هَلْ يَرَىٰكُم مِّنْ أَحَدٍۢ ثُمَّ ٱنصَرَفُوا۟ ۚ صَرَفَ ٱللَّهُ قُلُوبَهُم بِأَنَّهُمْ قَوْمٌۭ لَّا يَفْقَهُونَ ﴾

“and whenever a surah is bestowed from on high, they look at one another [and say, as it were], "Is there anyone who can see what is in your hearts?" -and then they turn away. God has turned their hearts away [from the truth] - for they are people who will not grasp it.”

And whenever a sūra is revealed wherein is mention of them and the Prophet s recites it they look at one another desiring to flee and saying ‘Will anyone see you?’ if you get up and flee? and so if no one can see them they get up and leave otherwise they stay put. Then they turn away persisting in their disbelief. God turns their hearts away from guidance because they are a folk who do not understand the truth for they do not reflect on it.
