And Ibn Abi 'Umar narrated to us, saying: Sufyan narrated to us, saying: I heard Ziyad ibn Sa'd say: I heard Thabit al-A'raj narrating from Abu Hurayrah that the Prophet, peace and blessings be upon him, said: "The worst food is the food of the wedding feast [walimah]: it is withheld from those who come to it, while those who refuse it are invited to it. And whoever does not accept the invitation has disobeyed Allah and His Messenger."
