Rafi' ibn Khudayj and Sahl ibn Abi Hathama reported that 'Abdullah ibn Sahl and Muhayyisa ibn Mas'ud came to Khaybar and parted when they were among the palm trees. 'Abdullah ibn Sahl was murdered. 'Abdu'r-Rahman ibn Sahl and Huwayyisa and Muhayyisa, the sons of Mas'ud came to the Prophet, may Allah bless him and grant him peace, and spoke to him about their (murdered) companion. 'Abdu'r-Rahman, the youngest of those present, began to speak, but the Prophet, may Allah bless him and grant him peace, said, "Let the oldest speak first." (or "Exalt the eldest.") They spoke about their companion and the Prophet, may Allah bless him and grant him peace, asked, "Will fifty of you take an oath that you are entitled to the blood-money of your murdered man?" They replied, "Messenger of Allah, this is something which we did not see." He said, "Then will the Jews exonerate themselves by the oaths of fifty of them?" They protested, "Messenger of Allah, they are unbelievers!" So the Messenger of Allah, may Allah bless him and grant him peace, himself paid his blood money."
