Musannaf Ibn Abi Shayba 28:437

'Adi ibn Yunus and Mu'tamir ibn Sulayman narrated to us, from al-Akhdar ibn 'Ajlan, from Abu Bakr al-Hanafi, from Anas ibn Malik, that the Prophet, peace and blessings of Allah be upon him, sold a saddle blanket and a drinking vessel to the highest bidder. However, Mu'tamir said: From Anas ibn Malik, from a man of the Ansar, from the Prophet, peace and blessings of Allah be upon him.
