وَإِذَا مَآ أُنزِلَتۡ سُورَةٞ نَّظَرَ بَعۡضُهُمۡ إِلَىٰ بَعۡضٍ هَلۡ يَرَىٰكُم مِّنۡ أَحَدٖ ثُمَّ ٱنصَرَفُواْۚ صَرَفَ ٱللَّهُ قُلُوبَهُم بِأَنَّهُمۡ قَوۡمٞ لَّا يَفۡقَهُونَ ١٢٧
And whenever a sūrah is revealed, they look at each other, [as if saying], "Does anyone see you?" and then they dismiss themselves. Allāh has dismissed their hearts because they are a people who do not understand.
Translation: Saheeh International (English)
Each word's meaning and sound
Whenever Allah reveals a sūrah to the Messenger (peace be upon him), mentioning the states of the hypocrites, the hypocrites would look at one another, saying ‘Does anyone see you?’ If no one is looking at them, they leave the gathering. Allah turned their hearts away from guidance and goodness, and leaves them, because they are a people who do not understand.
