Narrated Abu Salamah bin Abdur-Rahman and Sulaiman bin Yasar: On the authority of some men of the Ansar: The Prophet صلی اللہ علیہ وسلم said to the Jews and started with them: Fifty of you should take the oaths. But they refused (to take the oaths). He then said to the Ansar: Prove your claim. They said: Do we take the oaths without seeing, Messenger of Allah? The Messenger of Allah صلی اللہ علیہ وسلم then imposed the blood-wit on the Jews because he (the slain) was found among them.
