‘Abdullah bin Sahi Al-Anasri and Muhayysah bin Mas’ud went out to Khaibar and went their separate ways to go about their business. ‘Abdullah bin Sahl Al-Anasari was killed and Muhayysah. ‘Abdur-Rahman, who was the brother of the victim, and Huwayysah, came to the Messenger of Allah. ‘Abdur-Rahman started to speak, but the prophert said to him: “Let the elders speak first.” So Muhayysah and Huwayysah spoke and told him about the case of ‘Abdullah bin Sahl. The Messenger of Allah said: “Will you swear fifty oaths, then you will receive compensation or be entitled to retaliate?” They said: “How can we swear an oath when we did not witness (what happened) and we were not there?” The Messenger of Allah 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. (One of the narrators) Bushair said: ‘One of those camels kicked me in a Mirbad of ours.”‘
