'Abdur-Rahman bin Sahl and Huwhayysah, and Muhayysah, the tow sons of Nas'ud, came to the Messenger of Allah, and "Abdur-Rahman started to speak, but the Messenger of Allah said: "Let the elders speak first," for he was the youngest of them. So he fell silent and they (the other two) spoke. The Messenger of Allah said: "Will you sear fifty oaths, then you will receive compensation or be entitled to retaliate?" They said: "O Messenger of Allah, how can we a wear and 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: "O Messenger of Allah, how can we accept the oath of a disbelieving people?" So the Messenger of Allah paid the blood money himself.
