'Abdullah bin Sahl and Muḥaiyiṣa bin Mas'ûd bin Zaid set out to Khaibar, the inhabitants of which had a peace treaty with the Muslims at that time. They parted and later on Muḥaiyiṣa came upon 'Abdullah bin Sahl and found him murdered agitating in his blood. He buried him and returned to Al-Madîna. ' Abdur-Rahmân bin Sahl, Muḥaiyiṣa and Huwaiyiṣa, the sons of Mas'ûd came to the Prophet (ﷺ) and ' Abdur-intended to talk, but the Prophet (ﷺ) said (to him), "Let the eldest of you speak, 'Abdur-Rahmân was the youngest. ' Abdur-kept silent and the other two spoke. The Prophet (ﷺ) said, "If you swear as to who has committed the murder, you will have the right to take your right from the murderer?" They said, "How should we swear if we did not witness the murder or see the murderer?" The Prophet (ﷺ) said, "Then the Jews can clear themselves from the charge by taking Al-Qasâma (an oath taken by men that it was not they who committed the murder)." They said, "How should we believe in the oaths of Al-Kâfirûn (disbelievers in Allâh, in His Oneness and in His Messenger (ﷺ) Muḥammad)?" So, the Prophet (ﷺ) himself paid the blood money (of Abdullâh). [4:398-0.B]
