It is narrated from Zur bin Jish, he says: I was present in the service of Sayyiduna Ali, may Allah be pleased with him, when Ibn Jurmuz sought permission to enter from him. Sayyiduna Ali, may Allah be pleased with him, said: Give glad tidings of Hell to the killer of the son of Sayyida Safiyyah, that is, Sayyiduna Zubair bin Al-Awwam, may Allah be pleased with him. After this, Sayyiduna Ali, may Allah be pleased with him, said: I heard the Messenger of Allah, peace and blessings be upon him, saying that every prophet has a disciple, and my disciple is Zubair. Imam Sufyan said: By disciple is meant helper.
