[Machine] I said, "O Messenger of Allah, what do you think if a man struck me with a sword and cut off my hand, then took refuge from me by a tree and said, 'There is no god but Allah. Should I kill him?" He replied, "No." I repeated this question two or three times, and he answered, "No, unless he is like him (i.e., the attacker) before he said what he said, and you would be like him before you did what you did."  

قُلْتُ يَا رَسُولَ اللهِ أَرَأَيْتَ رَجُلًا ضَرَبَنِي بِالسَّيْفِ فَقَطَعَ يَدِي ثُمَّ لَاذَ مِنِّي بِشَجَرَةٍ ثُمَّ قَالَ لَا إِلَهَ إِلَّا اللهُ أَقْتُلُهُ؟ قَالَ لَا فَعُدْتُ مَرَّتَيْنِ أَوْ ثَلَاثًا فَقَالَ لَا إِلَّا أَنْ تَكُونَ مِثْلَهُ قَبْلَ أَنْ يَقُولَ مَا قَالَ وَيَكُونَ مِثْلَكَ قَبْلَ أَنْ تَفْعَلَ مَا فَعَلْتَ
