سنن نسائی · Hadith 4738

It was narrated from ‘Alqamah bin Wa’il Hadarmi that his father said: “A man who had killed someone was brought to the Messenger of Allah صلی اللہ علیہ وآلہ وسلم , and he was brought by the heir of the victim. The Messenger of Allah صلی اللہ علیہ وآلہ وسلم said to him: ‘Will you forgive him?’ He said: ‘No.’ He said: ‘Will you kill him?’ He said: ‘Yes.’ He said: ‘Go away.’ Then when he went away, he called him back and said: ‘Will you forgive him?’ He said: ‘No.’ He said: ‘Will you accept the Diyah?’ He said: ‘No.’ He said: ‘Will you kill him?’ He said: ‘Yes.’ He said: ‘Go away.’ Then when he had gone he said: ‘If you forgive him, he will carry your sin and the sin of your companion (the victim).’ So he forgave him and let him go.” He said: “And I saw him dragging his string.” (Sahih).
