In-book no 3399حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنِ ابْنِ شِهَابٍ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّهُ كَانَ يَقُولُ بِئْسَ الطَّعَامُ طَعَامُ الْوَلِيمَةِ يُدْعَى إِلَيْهِ الأَغْنِيَاءُ وَيُتْرَكُ الْمَسَاكِينُ فَمَنْ لَمْ يَأْتِ الدَّعْوَةَ فَقَدْ عَصَى اللَّهَ وَرَسُولَهُ .
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).
