It is narrated from Hasan that a man came to Sayyiduna Zubair bin Al-Awwam (may Allah be pleased with him) and said: Shall I kill Ali (may Allah be pleased with him) for you? He replied: How will you kill him when he has armies with him? The man said: I will apparently join him, and then, finding him unaware, I will kill him. He said: No, do not do that, because the Messenger of Allah (peace and blessings be upon him) said: Faith prevents killing after granting protection; a believer does not kill after granting protection.
