Musnad Ahmad 1171:1

'Abd al-Rahman ibn Mahdi narrated to us, he said: Sufyan narrated to me, from Mansur, from Rib'i, from his wife, from the sister of Hudhayfah, she said: The Messenger of Allah (peace and blessings of Allah be upon him) addressed us and said: "O assembly of women, is there not for you in silver that with which you may adorn yourselves? Verily, there is no woman among you who adorns herself with gold and displays it, but that she will be punished for it."
