Musannaf Ibn Abi Shaybah 29632 — Reports on the qasamah

Ibn Yasar also reported the like of this from the Prophet (peace and blessings be upon him), except that he said: Abd al-Rahman, the brother of the slain man, went to speak, and the Prophet (peace and blessings be upon him) said: "Call the eldest, call the eldest." So their eldest spoke. The Messenger of Allah (peace and blessings be upon him) said: "You will swear fifty oaths and be entitled, or they will swear fifty oaths for you." The narrator said: They said: "O Messenger of Allah (peace and blessings be upon him), how can we accept the oaths of a people who are disbelievers?" So the Prophet (peace and blessings be upon him) paid his blood money from his own funds.
