Musnad Ahmad

Rifa’ah bin Shaddad says that once I went to Mukhtar, he placed a cushion for me and said, “If my brother Jibra’il (peace be upon him) had not gotten up from this, I would have placed this cushion for you.” I was standing by Mukhtar’s bedside at that time. When it became clear to me that he was a liar, by Allah, I intended to draw my sword and cut off his neck. But then I remembered a hadith which ‘Amr bin al-Hamq (may Allah be pleased with him) had narrated to me, that I heard the Prophet Muhammad (peace and blessings be upon him) say: “Whoever gives a Muslim security for his life and then kills him afterwards, I am free from the killer.”
