Musnad Abu Ya'la al-Mawsili 150:267

Uqbah narrated to us, Yunus narrated to us, Mis'ar bin Kidam narrated to us, from al-Miqdam bin Shurayh bin Hani, from Aisha, who said: The Messenger of Allah (ﷺ) would be brought a vessel, and I would take it and place my lips upon it. Then he would take it and place his lips upon the place of my lips. And I would take the bone and bite from it, then he would place his mouth upon the place of my mouth, while I was menstruating.
