Sayyiduna Abu Hurayrah (may Allah be pleased with him) said: "The food of the wedding feast (walimah) is the worst food, because the rich are invited to it and the poor are left out; and whoever does not come to the invitation of the wedding feast has disobeyed Allah and His Messenger (peace and blessings be upon him)." In the narration of Abu Abdullah: "It is the worst food."
