Narrated by Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: The most transgressive person in the sight of Allah is the one who kills in the Haram, or kills someone who did not kill, or takes revenge for the days of ignorance.

It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that in the year of the conquest of Makkah, the Messenger of Allah, peace and blessings be upon him, entered Makkah while there was a helmet on his head. When he, peace and blessings be upon him, removed it, a man came to him and said: Ibn Khatal is hanging onto the curtains of the Ka'bah. He, peace and blessings be upon him, said: Kill him.

Narrated from Sayyiduna Sahl bin Abi Hathmah (may Allah be pleased with him): Abdullah, the brother of Banu Harithah, set out towards Khaybar with some men from Banu Harithah to collect dates. Sayyiduna Abdullah bin Sahl (may Allah be pleased with him) had his neck broken (i.e., he was killed) and was thrown at the place where the water flowed from one of the springs of Khaybar. When they found their companion missing, they went out in search of him until they found him murdered. Then they buried him and later presented themselves before the Noble Prophet (peace and blessings be upon him). Abdullah’s brother, Abdur Rahman bin Sahl, and his two cousins, Huwayyisah and Muhayyisah, who were older than Abdur Rahman, but Abdur Rahman was braver than all of them and was also the heir to the murdered man’s blood, these individuals came to the Messenger of Allah (peace and blessings be upon him), and Abdur Rahman began to speak before his cousins Huwayyisah and Muhayyisah. But the Prophet (peace and blessings be upon him) said: Let the elder speak, let the elder speak. So Abdur Rahman stepped back and Huwayyisah spoke, then Muhayyisah, and finally Abdur Rahman explained the situation and said: O Messenger of Allah! Our brother has been attacked, and in Khaybar our only enemies are the Jews. The Messenger of Allah (peace and blessings be upon him) said: Name your killer in such a way that fifty men from among you swear oaths that we will hand over the killer to you. They said: O Messenger of Allah (peace and blessings be upon him)! How can we swear oaths about an incident at which we were not present? The Prophet (peace and blessings be upon him) said: Then the Jews will swear fifty oaths and will be acquitted of your companion’s blood. They said: O Messenger of Allah! We will not accept the oaths of the Jews; the disbelief in which they are involved is a greater crime than a sinful oath. Then the Messenger of Allah (peace and blessings be upon him) paid the blood money for the murdered man from his own side in the form of one hundred she-camels. Sahl says: I have not forgotten to this day that among them was a red she-camel, which kicked me while I was gently driving it.

It is narrated from an Ansari companion that in the time of ignorance (Jahiliyyah), in the case of bloodshed, there was Qasamah. The Messenger of Allah, peace and blessings be upon him, maintained it in the same way as it was in Jahiliyyah. And some Ansari people from Banu Harithah accused the Jews regarding their murdered man, and the Prophet, peace and blessings be upon him, made a decision in the light of Qasamah.

It is narrated from Sayyiduna Abu Sa'id Khudri, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, found a murdered person between two settlements. The Prophet, peace and blessings be upon him, ordered the distance between the two settlements to be measured. It is as if I can still see the handspan of the Messenger of Allah, peace and blessings be upon him. Then he held the nearer settlement responsible for the murder.
