سَيَحْلِفُونَ بِٱللَّهِ لَكُمْ إِذَا ٱنقَلَبْتُمْ إِلَيْهِمْ لِتُعْرِضُوا۟ عَنْهُمْ ۖ فَأَعْرِضُوا۟ عَنْهُمْ ۖ إِنَّهُمْ رِجْسٌۭ ۖ وَمَأْوَىٰهُمْ جَهَنَّمُ جَزَآءًۢ بِمَا كَانُوا۟ يَكْسِبُونَ
They will swear by Allah unto you, when ye return unto them, that ye may let them be. Let them be, for lo! they are unclean, and their abode is hell as the reward for what they used to earn.
