وَمِمَّنۡ حَوۡلَكُم مِّنَ ٱلۡأَعۡرَابِ مُنَٰفِقُونَۖ وَمِنۡ أَهۡلِ ٱلۡمَدِينَةِ مَرَدُواْ عَلَى ٱلنِّفَاقِ لَا تَعۡلَمُهُمۡۖ نَحۡنُ نَعۡلَمُهُمۡۚ سَنُعَذِّبُهُم مَّرَّتَيۡنِ ثُمَّ يُرَدُّونَ إِلَىٰ عَذَابٍ عَظِيمٖ

Wa mimmann hawlakum minal A'raabi munaafiqoona wa min ahlil Madeenati maradoo 'alan nifaaq, laa ta'lamuhum nahnu na'lamuhum; sanu'azzibuhum marrataini summa yuraddoona ilaa 'azaabin 'azeem

Certain of the desert Arabs round about you are hypocrites, as well as (desert Arabs) among the Medina folk: they are obstinate in hypocrisy: thou knowest them not: We know them: twice shall We punish them: and in addition shall they be sent to a grievous penalty.
