Humayd bin Hilal said: Abu al-Aliyah came to me and a companion of mine and said: Come, for you two are younger than me and better at retaining hadith than me. Then he took us along until he brought us to Bishr bin Asim al-Laythi and said: Narrate your hadith to these two. Bishr said: Sayyiduna Uqbah bin Malik (may Allah be pleased with him) narrated to us (and he was from his clan); he said: The Messenger of Allah (peace and blessings be upon him) sent out a detachment, and it raided a people. A man from that people broke away and fled, and a man from the detachment went after him with his sword drawn. The man who had broken away said: I am a Muslim. But he paid no heed to what he said. The narrator said: He struck him and killed him. The matter reached the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) said something severe about it, which reached the killer. The narrator said: Once, while the Messenger of Allah (peace and blessings be upon him) was delivering a sermon, the killer said: By Allah, O Messenger of Allah! He only said what he said to save himself from being killed. The Messenger of Allah (peace and blessings be upon him) turned away from him and from the people on his side, and continued his sermon. Then he said a second time: By Allah! He only said what he said to save himself from being killed. The Messenger of Allah (peace and blessings be upon him) turned away from him and from the people on his side, and continued his sermon. Then he could not hold back and said it a third time: By Allah! He only said what he said to save himself from being killed. The Messenger of Allah (peace and blessings be upon him) turned towards him, with displeasure evident on his face, and then said: "Allah has refused me concerning whoever kills a believer." He (peace and blessings be upon him) said this three times.

Humayd bin Hilal said: A man brought me and Bishr bin Asim together, and he narrated to me from Sayyiduna Uqbah bin Malik (may Allah be pleased with him) that an army of the Messenger of Allah (peace and blessings be upon him) fell upon the people of a watering place early in the morning. A man from the people of the watering place rose up, and a man from the Companions of the Prophet (peace and blessings be upon him) attacked him. He said: I am a Muslim. But he killed him. When they came to the Prophet (peace and blessings be upon him), he (peace and blessings be upon him) was informed of it. He (peace and blessings be upon him) stood up to deliver a sermon, praised and extolled Allah, and then he (peace and blessings be upon him) said: "Amma ba'd (to proceed): What is the matter with a Muslim that he kills a Muslim while he is saying: I am a Muslim?" At that, he said: O Messenger of Allah! He only said it to save himself. He (peace and blessings be upon him) gestured like this and turned his face away from him, then said: "Allah has refused me concerning whoever kills a Muslim." He (peace and blessings be upon him) said this three times.

Sayyiduna Uqbah bin Malik (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) stood on the pulpit in Ramadan and delivered a sermon. He (peace and blessings be upon him) said: "I stood on this pulpit while I knew (which night was) Laylat al-Qadr, so seek it in the odd nights of the last ten."
