وَمِمَّنْ حَوْلَكُمْ مِنَ الْأَعْرَابِ مُنَافِقُونَ ۖ وَمِنْ أَهْلِ الْمَدِينَةِ ۖ مَرَدُوا عَلَى النِّفَاقِ لَا تَعْلَمُهُمْ ۖ نَحْنُ نَعْلَمُهُمْ ۚ سَنُعَذِّبُهُمْ مَرَّتَيْنِ ثُمَّ يُرَدُّونَ إِلَىٰ عَذَابٍ عَظِيمٍ

Surah At-Tawbah : 101
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.
