Amr bin Shu'aib narrates from his father, who narrates from his grandfather: Sayyiduna Muhayyisa bin Mas'ud (may Allah be pleased with him), Sayyiduna Huwayyisa bin Mas'ud (may Allah be pleased with him), Sayyiduna Abdur Rahman bin Sahl (may Allah be pleased with him), and Sayyiduna Abdullah bin Sahl (may Allah be pleased with him) went to Khaybar. There, these gentlemen separated from each other for their work, then they found Sayyiduna Abdullah bin Sahl (may Allah be pleased with him) murdered. These gentlemen returned and presented themselves before the Prophet Muhammad (peace and blessings be upon him) and informed him about this matter. The Prophet (peace and blessings be upon him) said to them: "You may have fifty people swear an oath as qasamah and thus punish the killer." But this was not acceptable to them. They said: "O Messenger of Allah! How can we swear an oath about the unseen? How can we swear about a matter in which we were not present?" The Prophet (peace and blessings be upon him) said: "Then fifty people from the Jews will swear an oath and be acquitted." They said: "O Messenger of Allah! Should we accept the oaths of the disbelievers?" (The narrator says:) Then zakat wealth was brought to the Prophet (peace and blessings be upon him), so the Prophet (peace and blessings be upon him) himself paid the blood money (diyah) for the murdered man.

Bashir bin Yasar narrates: A companion from the Ansar, whose name was Sayyiduna Sahl bin Abu Hathma (may Allah be pleased with him), related this incident. He went to Khaybar with some members of his tribe. There, they became separated from each other, and then they found one of their men murdered. So, they said to those among whom they found the murdered man, "Why did you kill our companion?" Those people replied, "We did not kill him, nor do we know anything about the killer." Then these people presented themselves before the Prophet Muhammad (peace be upon him) and said, "O Messenger of Allah! We went to Khaybar, and there we found one of our men murdered." The Prophet (peace be upon him) said, "Let the elder speak first." The Prophet (peace be upon him) said to them, "Present evidence regarding who killed him." They replied, "We have no evidence." The Prophet (peace be upon him) said, "Then (those Jews) should take an oath (and they will be acquitted)." They said, "We are not satisfied with the oaths of the Jews." The narrator states: The Prophet (peace be upon him) also did not like that the blood of the murdered man should go in vain, so he himself paid one hundred camels from the zakat camels as blood money.

This narration is also transmitted with another chain of transmission.

Sayyiduna Sahl bin Abu Hathma (may Allah be pleased with him) narrates: Some individuals from the Ansar went to Khaybar, and there one of them was killed. This matter was presented before the Prophet (peace and blessings be upon him), so he said: "Where is your proof?" They replied: "We have no proof." The Prophet (peace and blessings be upon him) said: "Then the oath of (the Jews) will settle the matter." They said: "Then the Jews will (one by one) kill us." The Prophet (peace and blessings be upon him) said: "Then you take the oath." They said: "We were not present there." The narrator states: From the wealth that came to the Prophet (peace and blessings be upon him), he paid the blood money for the (murdered) person.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings of Allah be upon him): "The claimant is required to present evidence, and the one who denies is required to take an oath, except that the ruling of Qasamah is different."

Amr bin Shu'aib, from his father, from his grandfather, narrates that the Prophet Muhammad (peace be upon him) said: "The burden of proof is upon the claimant, and an oath is required from the one who denies, except in the case of Qasamah, for which the ruling is different."

The same narration is also transmitted with another chain; ‘Abdur Razzaq has transmitted it as a mursal narration in contrast.

Abdul Malik bin Umair narrates: I was present with Sayyiduna Ali (may Allah be pleased with him) when a man from Banu ‘Ajl, Mustawrid bin Qabisah, who had left Islam and become a Christian, was brought to him. Sayyiduna Ali (may Allah be pleased with him) asked him: "What have I been told about you?" He asked: "What have you been told about me?" Sayyiduna Ali (may Allah be pleased with him) said: "I have been told that you have become a Christian." He said: "I am upon the religion of Sayyiduna Masih (peace and blessings be upon him)." Sayyiduna Ali (may Allah be pleased with him) said to him: "I am also upon the religion of Sayyiduna Masih (peace and blessings be upon him)." Sayyiduna Ali (may Allah be pleased with him) asked him: "What do you say about him (i.e., Sayyiduna Masih)?" The answer that the man gave, I did not understand. Sayyiduna Ali (may Allah be pleased with him) ordered: "Kill him." So he was killed. (The narrator says:) I asked the one next to me: "What did he say?" He replied: "He said: Sayyiduna Masih (peace and blessings be upon him) is his Lord."

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: A man had an umm walad (a slave woman who had borne him children), from whom he had two sons, both of whom were like pearls. She used to speak disrespectfully about the Prophet Muhammad (peace be upon him). The man forbade her, but she did not desist. He rebuked her, but she still did not desist. One night, the woman mentioned the Prophet Muhammad (peace be upon him) with disrespectful words, so the man could not bear it. He took a spade and stabbed it into the woman's belly (which caused her death). When this case was presented before the Prophet Muhammad (peace be upon him), he said: "Bear witness, the blood of this woman is wasted (i.e., there is no retribution for her killing)." These are the words of the narrator named Ibn Karama.

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: There was a blind man whose slave woman used to speak disrespectfully about the Prophet (peace and blessings be upon him). The man forbade her, but she did not desist. He scolded her, but she still did not desist. One night, when she again began to speak disrespectfully about the Prophet (peace and blessings be upon him), the man killed her. In the morning, this matter was mentioned before the Prophet (peace and blessings be upon him). The blind man stood up and said: "O Messenger of Allah! I am the owner of this woman. She used to speak disrespectfully about you. I forbade her, but she did not desist. I scolded her, but she still did not desist. I have two children from her, who are like pearls. She was my companion (beloved). Last night, she spoke disrespectfully about you, so I killed her." The Prophet (peace and blessings be upon him) said: "Bear witness, her blood is wasted."
