Musannaf Ibn Abi Shayba 19:255

Abu Bakr narrated to us, he said: Waki’ narrated to us, from Sufyan, from Abu Ishaq, from al-Hasan, that a woman from the Dhubayriyyin committed adultery. Her family clothed her in a coat of mail (iron armor), and she was brought up to Ali, so he struck her while she was wearing it.
