Mu'jam Kabir Tabarani 850 — I travelled with al-Muthanna bin Abd

Jabir bin Subh (may Allah have mercy on him) narrates: I travelled with al-Muthanna bin Abd al-Rahman al-Khuza'i (may Allah have mercy on him) to Wasit. Whenever he ate, he said Bismillah, and when it came to the last morsel he would say: "Bismillahi awwalahu wa akhirahu (In the name of Allah, at its beginning and its end)." I asked him about that, and he said: My grandfather, Sayyiduna Umayyah bin Makhshi (may Allah be pleased with him), who was one of the Companions of the Prophet (peace and blessings be upon him), told me that a man was eating in the presence of the Prophet (peace and blessings be upon him) and did not say Bismillah. When he reached the last morsel, he said: "In the name of Allah, at its beginning and its end." At that the Prophet (peace and blessings be upon him) said: "Satan kept eating with him until he said 'at its beginning and its end'; then Satan vomited up everything he had eaten."
