Hazrat Humaid bin Hilal narrates that Hazrat Abu Al-Aaliyah came to me and one of my companions and said: Come, indeed both of you are younger than me and better at preserving hadith than I am. So we went until we presented ourselves before Hazrat Bishr bin Asim Laithi. Hazrat Abu Al-Aaliyah said: Relate your hadith to these two. He said that Hazrat Uqbah bin Malik Laithi narrated to us that the Noble Prophet (peace and blessings be upon him) sent out an army which attacked a tribe. A man from that tribe started to run, so a man from the army chased him with a drawn sword. The man who was running from the tribe said: Indeed, I am a Muslim. The man from the army did not pay attention to his words and struck him, killing him. Then this matter was conveyed to the Noble Prophet (peace and blessings be upon him), who was delivering a sermon at the time. The killer said: O Prophet of Allah! By Allah, whatever he said, he only said it to save himself from being killed. The Noble Prophet (peace and blessings be upon him) turned away from him and from those who were with him, and he did this twice; each time, the Noble Prophet (peace and blessings be upon him) turned his face away from him. The man could not bear it, so he repeated the same thing a third time. Then the Noble Prophet (peace and blessings be upon him) turned his face towards him, and anger was apparent on his face. The Noble Prophet (peace and blessings be upon him) said: Indeed, Allah has refused me regarding the one who kills a believer. The Noble Prophet (peace and blessings be upon him) said this three times.
