Ibn Abi Najih narrates from his father, who named a man who heard Sayyiduna Ali (may Allah be pleased with him) in Kufah saying: I intended to propose to the Messenger of Allah (peace and blessings be upon him) for his daughter in marriage, but I remembered that I had nothing at all. Then I remembered his (peace and blessings be upon him) kindness and generosity, so I made the proposal. He (peace and blessings be upon him) asked: "Where is the Hutami coat of mail that I gave you on such-and-such a day?" He said: It is with me. He (peace and blessings be upon him) said: "Give it to her."
