It was narrated from Sahl bin Abi Hathmah that ‘Abdullah bin Sahl and Mul bin Mas’ud bin Zaid went to Khaibar, and at that time there was a peace treaty. They went their separate ways to go about their business, then Muliayy came upon ‘Abdullah bin Sahl lying dead in a pool of blood. He buried him, then he came to Al-Madinah. ‘Abdur Rahnian bin Sahl, Huwayysah, and Mubayy came to the Messenger of Allah صلی اللہ علیہ وآلہ وسلم and ‘Abdur-Rahman to speak, but he was the youngest of them, so the essenger of Allah said: “Let the elders speak first.” So he fell silent and they (the other two) spoke. The Messenger of Allah صلی اللہ علیہ وآلہ وسلم i said: “Will you swear fifty oaths, then you will receive compensation or be entitled to retaliate?” They said: “Messenger of Allah صلی اللہ علیہ وآلہ وسلم, how can we swear an oath when we did not witness, and did not see (what happened)?” He said: “Then can the Jews swear fifty oaths declaring their innocence?” They said: “Messenger of Allah صلی اللہ علیہ وآلہ وسلم, how can we accept the oath of a disbelieving people?” So the Messenger of Allah صلی اللہ علیہ وآلہ وسلم paid the blood money himself.
