Qur'ān 9:95 · At-Tawbah (التوبة)

سَيَحْلِفُونَ بِٱللَّهِ لَكُمْ إِذَا ٱنقَلَبْتُمْ إِلَيْهِمْ لِتُعْرِضُوا۟ عَنْهُمْ ۖ فَأَعْرِضُوا۟ عَنْهُمْ ۖ إِنَّهُمْ رِجْسٌۭ ۖ وَمَأْوَىٰهُمْ جَهَنَّمُ جَزَآءًۢ بِمَا كَانُوا۟ يَكْسِبُونَ

They will swear by Allah to you when you return to them that you would leave them alone. So leave them alone; indeed they are evil; and their refuge is Hell as recompense for what they had been earning.
