Rifa’ah bin Shaddad says: One day I was standing by the bedside of Mukhtar. When it became clear to me that he was a liar, by Allah, I intended to draw my sword and strike off his neck. But then I remembered a hadith which ‘Amr bin al-Hamq (may Allah be pleased with him) narrated to me, that I heard the Prophet Muhammad (peace and blessings be upon him) say: Whoever grants safety to a Muslim for his life and then kills him afterwards, a banner of treachery will be raised for him on the Day of Resurrection.
