Abu Huraira (Allah be pleased with him) used to say: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)
Scholarly Authentication
The label above is the grade most of these scholars gave — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. Each scholar's own wording:
Every narration in Sahih Muslim is accepted as Sahih (authentic) by the established status of the book.
