There was peace during those days and (this place) was inhabited by the Jews. They parted company for their (respective) needs. 'Abdullah B.Sahl was killed, and his dead body was found in a tank. His companion (Muhayyisa) buried him and came to Madinah, and the brothers of the slain 'Abdul Rahman bin Sahl. and Muhayyisa and Huwayyisa told Allah's Messenger ( صلی اللہ علیہ وسلم ) the case of 'Abdullah and the place where he had been murdered. Bushair reported on the authority of one who had seen Allah's Messenger ( صلی اللہ علیہ وسلم ) that he had said to them: You take fifty oaths and you are entitled to blood-wit of (one) slain among you (or your companion). They said: Messenger of Allah, we neither saw (with our own eyes this murder) nor were we present there. Thereupon (Allah's Messenger is reported to have said: Then the Jews will exonerate themselves by taking fifty oaths. They said: Allah's Messenger, how can we accept the oath of unbelieving people? Bushair said that Allah's Messenger ( صلی اللہ علیہ وسلم ) paid the blood-wit himself.
