وَمِمَّنْ حَوْلَكُم مِّنَ ٱلْأَعْرَابِ مُنَٰفِقُونَ ۖ وَمِنْ أَهْلِ ٱلْمَدِينَةِ ۖ مَرَدُوا۟ عَلَى ٱلنِّفَاقِ لَا تَعْلَمُهُمْ ۖ نَحْنُ نَعْلَمُهُمْ ۚ سَنُعَذِّبُهُم مَّرَّتَيْنِ ثُمَّ يُرَدُّونَ إِلَىٰ عَذَابٍ عَظِيمٍۢ
And among those around you of the wandering Arabs there are hypocrites, and among the townspeople of Al-Madinah (there are some who) persist in hypocrisy whom thou (O Muhammad) knowest not. We, We know them, and We shall chastise them twice; then they will be relegated to a painful doom.
Surah At-Tawba(9:101)
