Musannaf Ibn Abi Shaybah 30882 — What protects blood and spares a man

Humayd bin Hilal said: Abu al-Aliyah came to me and to a companion of mine and said: Come along, for you two are younger than I am and better at retaining hadith than I am. So we went until we came to Bishr bin Asim al-Laythi. Abu al-Aliyah said: Relate your hadith to these two. He said that Sayyiduna Uqbah bin Malik al-Laythi (may Allah be pleased with him) related to us: The Prophet (peace and blessings be upon him) sent out a military detachment, which attacked a people. A man from those people broke away and ran, and a man from the detachment pursued him with a drawn sword. The man who was running from those people said: I am a Muslim. The man from the detachment did not consider what he said, and struck him and killed him. Then this was conveyed to the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) said something severe about it, and this reached the killer. Then, while the Prophet (peace and blessings be upon him) was delivering a sermon, the killer said: O Prophet of Allah! By Allah, whatever he said, he said only to save himself from being killed. The Prophet (peace and blessings be upon him) turned away from him and from those people who were next to him. He (peace and blessings be upon him) did this twice, and each time the Prophet (peace and blessings be upon him) turned his face away from him. Then he could not restrain himself, and he said the same thing a third time. Then the Prophet (peace and blessings be upon him) turned his face toward him, with displeasure evident on his (peace and blessings be upon him) face. He (peace and blessings be upon him) said: Indeed, Allah has refused me concerning the one who kills a believer. He (peace and blessings be upon him) said this three times.
