Musnad Abu Ya'la al-Mawsili 155:71

'Abd al-A'la ibn Hammad al-Narsi narrated to us, Hammad narrated to us, from Muhammad ibn 'Amr, from Abu Salamah, from Abu Hurayrah: That Abu Hind performed cupping on the Prophet, may Allah bless him and grant him peace, on the crown of his head. The Prophet, may Allah bless him and grant him peace, said: "O assembly of the Ansar, marry Abu Hind and marry [your women] to him." And he said: "If there is any good in anything you use for medical treatment, it is cupping."
