It is narrated through the same chain that Sayyiduna Anas (may Allah be pleased with him) said: I attended a wedding feast (walimah) of the Messenger of Allah (peace and blessings be upon him) in which there was neither bread nor meat. I asked: Then what was it, O Abu Hamzah? He said: "Sawiq (barley mush) and dates."
