It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) ate bone or he said meat, then performed prayer and did not perform ablution (again). Abu Bakr (may Allah have mercy on him) says that the chain of narration of the report (hadith) of Hammad bin Zaid is not connected. And we have made a mistake in its narration. Indeed, between Hisham bin Urwah and Muhammad bin Amr bin Ata, the narrator is Wahb bin Kaysan. Similarly, this hadith has been narrated by Yahya bin Saeed and Abdah bin Sulayman.
