إِنَّ ٱلَّذِينَ فَتَنُوا۟ ٱلْمُؤْمِنِينَ وَٱلْمُؤْمِنَـٰتِ ثُمَّ لَمْ يَتُوبُوا۟ فَلَهُمْ عَذَابُ جَهَنَّمَ وَلَهُمْ عَذَابُ ٱلْحَرِيقِ
Innal lazeena fatanul mu'mineena wal mu'minaati summa lam yatooboo falahum 'azaabu Jahannama wa lahum 'azaabul hareeq
For those who persecute believing men and women, and do not repent afterwards, there will be the torment of Hell and burning.
Indeed, those who persecuted the believing men and the believing women and then did not repent — for them is the punishment of jahannam, and for them is the punishment of the burning fire.
Repentance stays open even here: the sentence falls on those who persecuted and then did not turn back, which leaves a door for people who had burned others alive, and commentators have long remarked on the generosity of that clause. Fatanu comes from the same root as fitna, the testing of metal by fire, so the verb for what the persecutors did also describes what the believers underwent. Men and women are named separately, as both were at the trench.
