[Machine] I asked, O Messenger of Allah, what do you think if I differ with a polytheist and he strikes me twice, severing my hands. When I incline to strike him back, he says, "There is no god but Allah." Should I kill him or spare him? He replied, "Spare him." I asked, even if he severs my hands? He said, "Even if he does." I repeated this question two or three times, and then the Prophet ﷺ said, "If you kill him after he says, 'There is no god but Allah,' you will be like him before he said it, and he will be like you. But if you spare him, Allah will love you."  

قُلْتُ يَا رَسُولَ اللهِ أَرَأَيْتَ إِنِ اخْتَلَفْتُ أَنَا وَرَجُلٌ مِنَ الْمُشْرِكِينَ ضَرْبَتَيْنِ فَقَطَعَ يَدَيَّ فَلَمَّا أَهْوَيْتُ إِلَيْهِ لِأَضْرِبَهُ قَالَ لَا إِلَهَ إِلَّا اللهُ أَقْتُلُهُ أَمْ أَدَعُهُ؟ قَالَ «بَلْ دَعْهُ» قُلْتُ وَإِنْ قَطَعَ يَدَيَّ؟ قَالَ «وَإِنْ فَعَلَ» فَرَاجَعْتُهُ مَرَّتَيْنِ أَوْ ثَلَاثًا فَقَالَ النَّبِيُّ ﷺ إِنْ قَتَلْتَهُ بَعْدَ أَنْ قَالَ لَا إِلَهَ إِلَّا اللهُ فَأَنْتَ مِثْلُهُ قَبْلَ أَنْ يَقُولَهَا وَهُوَ مِثْلُكَ إِنْ قَتَلْتَهُ
