وَمِمَّن حَولَكُم مِنَ الأَعرابِ مُنافِقونَ ۖ وَمِن أَهلِ المَدينَةِ ۖ مَرَدوا عَلَى النِّفاقِ لا تَعلَمُهُم ۖ نَحنُ نَعلَمُهُم ۚ سَنُعَذِّبُهُم مَرَّتَينِ ثُمَّ يُرَدّونَ إِلىٰ عَذابٍ عَظيمٍ

Among the Desert Arabs around you, some are hypocrites, as well as among the city dwellers. They are persistent in hypocrisy. You don’t know them, but We certainly do. We will punish them twice; then they will be returned to a severe punishment.
