Sayyiduna Abu Hurairah (may Allah be pleased with him) says: The worst food is the food of a wedding banquet (walimah) in which the rich are invited and the poor are left out, and whoever does not accept the invitation disobeys Allah and His Messenger.
(Imam Ibn Hibban, may Allah have mercy on him, says:) Ibn Qutaybah narrated to us that this narration is transmitted from the Prophet Muhammad (peace and blessings be upon him) on the authority of Sayyiduna Abu Hurairah (may Allah be pleased with him). I have mentioned it briefly because all the students of Zuhri have transmitted this narration in the same way as a mawquf narration. The musnad narration is another one: "Whoever does not accept the invitation."
