Narrated Wail (bin Hujr): A man brought an Abyssinian to the Prophet صلی اللہ علیہ وسلم and said: This man has killed my nephew. He asked: How did you kill him? He replied: I struck his head with axe but I did not intend to kill him. He asked: Have you some money so that you pay his blood-wit? He said: No. He said: What is your opinion if I send you so that you ask the people (for money) and thus collect your blood-wit? He said: No. He asked: Will your masters give you his blood-wit (to pay his relatives)? He said: No. He said to the man. Take him. So he brought him out to kill him. The Messenger of Allah صلی اللہ علیہ وسلم said: If he kill him, he will be like him. This (statement) reached the man where he was listening to his statement. He said: He is here, order regarding him as you like. The Messenger of Allah صلی اللہ علیہ وسلم said: Leave him alone. And he once said: He will bear the burden of the sin of the slain and that of his own and thus he will become one of the Companions of Hell. So he let him go.

Narrated Abu Hurairah: A man was killed in the lifetime of the Prophet صلی اللہ علیہ وسلم . The matter was brought to the Prophet صلی اللہ علیہ وسلم . He entrusted him to the legal guardian of the slain. The slayer said: Messenger of Allah, I swear by Allah, I did not intend to kill him. The Messenger of Allah صلی اللہ علیہ وسلم said to the legal guardian: Now if he is true and you kill him, you will enter Hell-fire. So he let him go. His hands were tied with a strap. He came out pulling his strap. Hence he was called Dhu an-Nis'ah (possessor of strap).

Narrated Wail ibn Hujr: I was with the Prophet صلی اللہ علیہ وسلم when a man who was a murderer and had a strap round his neck was brought to him. He then called the legal guardian of the victim and asked him: Do you forgive him? He said: No. He asked: Will you accept the blood-money? He said: No. He asked: Will you kill him? He said: Yes. He said: Take him. When he turned his back, he said: Do you forgive him? He said: No. He said: Will you accept the blood-money? He said: No. He said: Will you kill him? He said: Yes. He said: Take him. After repeating all this a fourth time, he said: If you forgive him, he will bear the burden of his own sin and the sin of the victim. He then forgave him. He (the narrator) said: I saw him pulling the strap.
