Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said that Sayyiduna Ali (may Allah be pleased with him) said: When I married Fatimah (may Allah be pleased with her), the daughter of the Messenger of Allah (peace and blessings be upon him), I said: O Messenger of Allah (peace and blessings be upon him), let me consummate the marriage. He (peace and blessings be upon him) said: "Give her something." I said: O Messenger of Allah (peace and blessings be upon him), I have nothing. He (peace and blessings be upon him) said: "Where is your Hutami coat of mail?" Sayyiduna Ali (may Allah be pleased with him) said: It is with me. He (peace and blessings be upon him) said: "Give her that."
