Later, he joined them in the conversation. They mentioned to Allah’s Messenger (SAW) about the murder of Abdullah ibn Sahi. So he said to them, “Will you take fifty oaths naming the murderer that you may be entitled to take bloodmoney or revenge for your companion (or, he said, your slain man)?’ They submitted, “How can we swear when we have not witnessed”? He said, “The Jews will exonerate themseif by swearing fifty times.” They said, “How do we accept the oaths of a disbelieving people”? When he saw that, Allah’s Messenger (SAW) paid his bloodwit.
