and he said, ‘There is no god but Allah.’ I then stabbed him and killed him, but the matter weighed on my conscience, so I mentioned it to the Prophet (peace and blessings be upon him). He said:
‘Did you kill him after he had said, “There is no god but Allah”?’
I replied, ‘O Messenger of Allah, he said it only out of fear of the weapon.’
He said, ‘Why did you not split open his heart to ascertain whether he had said it [out of fear of the weapon] (1) or not?’
He continued repeating this until I wished that I had embraced Islam that very day.” (2).
It is also related in the two Sahih collections that al-Miqdād ibn al-Aswad (may Allah be pleased with him) said:
“I asked, ‘O Messenger of Allah, suppose I encounter an unbeliever who fights me, strikes one of my hands and severs it, then takes refuge from me behind a tree and says, “I have submitted to Allah.” May I kill him after he has said this?’
The Messenger of Allah (peace and blessings be upon him) replied, ‘Do not kill him.’
I said, ‘O Messenger of Allah, he severed my hand and then said [that] (3) after severing it. May I kill him?’
The Messenger of Allah (peace and blessings be upon him) replied, ‘Do not kill him. If you kill him, he will be in the same position as you were before you killed him, and you will be in the same position as he was before uttering the words he spoke.’” (4).
It has thus been established that these men killed people who were Muslims and whom it was not (5) lawful to kill. Yet the Prophet (peace and blessings be upon him) neither executed them nor held them liable for the slain through legal retaliation or blood money
