Sayyiduna Abu Rafi' (may Allah be pleased with him) said: When Sayyiduna Ali (may Allah be pleased with him) killed the standard-bearers on the day of Uhud, Jibril (peace be upon him) said: O Messenger of Allah, this is true solidarity. The Prophet (peace and blessings be upon him) said: "He is from me and I am from him." Jibril (peace be upon him) said: And I am from you both, O Messenger of Allah!
