It is narrated from Sayyiduna Sahl that the Prophet (peace and blessings be upon him) said to Huwayyisah, Muhayyisah, and Abdur Rahman (may Allah be pleased with them): "If fifty men among you swear an oath and say that the Jews killed him..." They said, "How can we swear an oath about something we have not seen with our own eyes?" The Prophet (peace and blessings be upon him) said: "Then fifty Jews will swear an oath to absolve themselves and say that they did not kill him." They said, "O Messenger of Allah! How can we trust their oath when they are polytheists?" Upon this, the Prophet (peace and blessings be upon him) paid the blood money from his own side.
