Sayyiduna Sahl bin Abi Hathmah (may Allah be pleased with him) narrates that Abdullah bin Sahl and Muhayyisah bin Mas'ud went out to Khaybar and separated for their needs, and Abdullah bin Sahl was killed. So he (Muhayyisah), Abd al-Rahman, the brother of the slain man, and Huwayyisah bin Mas'ud went to the Messenger of Allah (peace and blessings be upon him) and mentioned to him the killing of Abdullah bin Sahl. The Messenger of Allah (peace and blessings be upon him) said: "Will you swear fifty oaths and become entitled to the blood of your killer, or your companion?" They said: "O Messenger of Allah, we did not witness it and were not present." The Messenger of Allah (peace and blessings be upon him) said: "Then the Jews will clear themselves of your claim with fifty oaths?" They said: "O Messenger of Allah, how can we accept the oaths of a disbelieving people?" He stated that the Prophet (peace and blessings be upon him) paid his blood money from his own funds. Bushayr bin Yasar said: Sahl said: One of those camels kicked me in a pen of ours.
