It is narrated from Sayyiduna Miqdad bin Aswad (may Allah be pleased with him), he says: "O Messenger of Allah! What is your opinion regarding this: if I encounter a disbeliever, he fights with me, we both strike each other once, but he strikes my hand with a sword in such a way that he cuts it off, and then, to seek protection from me, he goes behind a tree and starts saying: 'I have become a Muslim for the sake of Allah.' O Messenger of Allah! Should I fight him now?" In another narration: "After he says this, should I kill him or leave him?" The Messenger of Allah (peace and blessings be upon him) said: "Do not kill him. If you kill him, then the state you were in before this killing, that is, your state of Islam, you will enter into his state, and the state he was in before accepting Islam, he will enter into yours."
