Maliks Muwatta Book 54, Hadith Number 26.

Section : Cupping and the Reward of the Cupper.

Malik related to me from Humayd at-Tawil that Anas ibn Malik said, “The Messenger of Allah, may Allah bless him and grant him peace, was cupped. Abu Tayba cupped him, and the Messenger of Allah, may Allah bless him and grant him peace, ordered him to be given a sa of dates and ordered his family to lessen what he paid them for his kitaba or kharaj.”
