The worst kind of food is the wedding feast to which the rich are invited and the poor are ignored. He who does not come to the feast, he in fact disobeys Allah and His Messenger (ﷺ).
Sahih Muslim Book 16, Hadith 124
← Previous Hadith If any one of you is invited, he should accept (the invitation). In case he is fasting, he should pray (in order to bless the inmates of the house), and if he is not fasting he should eat.

Sahih Muslim Book 16, Hadith 123 Next Hadith → I said to Zuhri: Abu Bakr, what does this hadith mean:" The worst kind of food is at a wedding feast of the rich"? He laughed and said: The food served in the feast given by the rich is not worst (in itself). Sufyan said: My father was rich, so I felt disturbed when I heard this hadith, so I asked Zuhri who said: I heard from 'Abd al-Rahman al-Alraj that he heard Abu Huraira (Allah he pleased with him) say: The worst kind of food is that served at the wedding feast. The rest of the hadith is the same.
