It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that he said: "I saw the Prophet (peace and blessings be upon him) during the Farewell Hajj, while he (peace and blessings be upon him) was circling the House (or it was the Day of Sacrifice), when a bone with meat on it was brought to him (peace and blessings be upon him). He (peace and blessings be upon him) tore some meat from it with his teeth and ate, and did not perform ablution."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Yahya bin Abi Kathir (may Allah have mercy on him) except Ayyub bin Utbah, and Anbasah bin Abd al-Wahid is alone in narrating it."
