“A man brought the killer of his relative to the Messenger of Allah ﷺ and the Messenger of Allah ﷺ said: 'Pardon him,' but the refused. He said: 'Take the blood money,' but he refused. He said: 'Go and kill him, but then you will be like him.’ Someone caught up with him and reminded him that the Messenger of Allah ﷺ had said: 'Go and kill him, but then you will be like him.’ So he let him go. He said: So he was seen dragging his strap going to his family. He said: It seemed that he had tied him up. It's narrated that AbdurRahman bin AlQasim said "Then it is not (permissible) for anyone after the Prophet ﷺ to say 'Go and kill him, but then you will be like him.' "
