Abdullah bin Sahl and Muhayyisah (may Allah be pleased with them both) went out to Khaybar because of hardship that had befallen them, and the two of them separated for some reason. Muhayyisah (may Allah be pleased with him) came and was told that Abdullah bin Sahl (may Allah be pleased with him) had been killed and thrown into a well or a spring. So he went to the Jews and said: "You killed him, by Allah!" They said: "By Allah, we did not kill him." Then he came to his people and told them the whole incident. Then he, his elder brother Huwayyisah, and Abd al-Rahman bin Sahl, the brother of the slain man (may Allah be pleased with them), came to the Prophet (peace and blessings be upon him). Muhayyisah (may Allah be pleased with him) wanted to speak, so he (peace and blessings be upon him) said: "Let the elder speak." So Huwayyisah (may Allah be pleased with him) spoke, then Muhayyisah (may Allah be pleased with him) spoke. He (peace and blessings be upon him) said: "Either they pay the blood money of your companion, or they must be ready for war." He (peace and blessings be upon him) wrote to them about this, and they wrote back: "By Allah, we did not kill him." Then he (peace and blessings be upon him) said to the three of them: "Will you take oaths and so become entitled to the blood of your companion?" They said: "No." He (peace and blessings be upon him) said: "Then shall the Jews take oaths?" They said: "They are not even Muslims." So he (peace and blessings be upon him) paid his blood money from his own funds. A hundred she-camels were sent to them until they were brought into their house. Sahl (may Allah be pleased with him) said: A red she-camel among them even kicked me.
