Musnad Ahmad 788:18

'Abd al-Razzaq narrated to us, 'Abd Allah ibn Sa'id ibn Abi Hind informed us, from his father, from a man, from Abu Musa, who said: The Messenger of Allah (peace and blessings of Allah be upon him) raised silk in his right hand and gold in his left hand, then said: "These are permitted for the females of my nation, and forbidden for its males."
