Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him) narrates: I prepared enough food for the Prophet (peace and blessings be upon him) and Sayyiduna Abu Bakr (may Allah be pleased with him) to suffice the two of them. I brought it to them both, and the Prophet (peace and blessings be upon him) said to me: "Go and bring thirty of the nobles of the Ansar to me!" This weighed heavily on me, and I said: "I have nothing more than this." I showed no attention to it, so the Prophet (peace and blessings be upon him) said: "Go and bring me thirty of the nobles of the Ansar!" I called those men and they came. The Prophet (peace and blessings be upon him) said: "Eat!" Those people ate the food until they had their fill, they bore witness that he is the Messenger of Allah, and then they pledged allegiance to him before leaving. Then the Prophet (peace and blessings be upon him) said: "Go and call sixty of the nobles of the Ansar to me!" Sayyiduna Abu Ayyub (may Allah be pleased with him) says: By Allah! I was more willing to call the sixty than I had been to call the thirty. Anyway, I called them and brought them. The Prophet (peace and blessings be upon him) said: "Wait!" Then those people ate the food until they had their fill and were about to leave; they bore witness that he is the Messenger of Allah, and they also pledged allegiance to the Prophet (peace and blessings be upon him) before leaving. Then the Prophet (peace and blessings be upon him) said: "Go and call ninety of the Ansar to me!" The narrator says: I was more willing to call the ninety and the sixty than I had been to call the thirty. I called them, and they ate the food until they had finished; then they bore witness that he is the Messenger of Allah (peace and blessings be upon him), then they pledged allegiance to the Prophet (peace and blessings be upon him) before leaving. The narrator says: So one hundred and eighty men ate my food, all of them from the Ansar.
Al-Tabarani recorded it, and its chain contains a narrator whom I do not know.
