Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) took silk and placed it in his right hand, and took gold and placed it in his left hand. Then he raised his hands and said: "Both of these are forbidden for the men of my Ummah."
(Imam Ibn Hibban, may Allah have mercy on him, says:) The narration that Sa'id bin Abu Hind has transmitted from Abu Musa regarding this is defective and not authentic.
