At Tawbah, 101 Ayah
9:101
وَمِمَّنۡ حَوۡلَكُم مِّنَ ٱلۡأَعۡرَابِ مُنَٰفِقُونَۖ وَمِنۡ أَهۡلِ ٱلۡمَدِينَةِ مَرَدُواْ عَلَى ٱلنِّفَاقِ لَا تَعۡلَمُهُمۡۖ نَحۡنُ نَعۡلَمُهُمۡۚ سَنُعَذِّبُهُم مَّرَّتَيۡنِ ثُمَّ يُرَدُّونَ إِلَىٰ عَذَابٍ عَظِيمٖ ١٠١
Wa Mimman Ĥawlakum Mina Al-'A`rābi Munāfiqūna ۖ Wa Min 'Ahli Al-Madīnati ۖ Maradū `Alá An-Nifāqi Lā Ta`lamuhum ۖ Naĥnu Na`lamuhum ۚ Sanu`adhdhibuhum Marratayni Thumma Yuraddūna 'Ilá `Adhābin `Ažīmin
And among those around you of the bedouins are hypocrites, and [also] from the people of Madinah. They have become accustomed to hypocrisy. You, [O Muhammad], do not know them, [but] We know them. We will punish them twice [in this world]; then they will be returned to a great punishment.
