It was narrated from 'Amr bin Shu'aib, from his father, from his grandfather, that: Huwayyisah and Muhayyisah , the sons of Mas'ud, and 'Abdullah and 'Abdur-Rahman the sons of Sahl, went out to search for food in Khaibar. 'Abdullah was attacked and killed, and mention of that was made to the Messenger of Allah ( صلی اللہ علیہ وسلم ). He said:“Will you swear an oath and establish your right to blood money?”They said:“O Messenger of Allah ( صلی اللہ علیہ وسلم ), how can we swear an oath when we did not witness anything?”He said:“Do you want the Jews to swear that they are innocent?”They said:“O Messenger of Allah ( صلی اللہ علیہ وسلم ), then they will kill us too.”So the Messenger of Allah ( صلی اللہ علیہ وسلم ) paid the blood money himself.
