باب الأَمْرِ بِإِجَابَةِ الدَّاعِي إِلَى دَعْوَةٍ ‏
Sahih Muslim 1432 b

Sufyan reported:

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.
وَحَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، قَالَ قُلْتُ لِلزُّهْرِيِّ يَا أَبَا بَكْرٍ كَيْفَ هَذَا الْحَدِيثُ شَرُّ الطَّعَامِ طَعَامُ الأَغْنِيَاءِ فَضَحِكَ فَقَالَ لَيْسَ هُوَ شَرُّ الطَّعَامِ طَعَامُ الأَغْنِيَاءِ ‏.‏ قَالَ سُفْيَانُ وَكَانَ أَبِي غَنِيًّا فَأَفْزَعَنِي هَذَا الْحَدِيثُ حِينَ سَمِعْتُ بِهِ فَسَأَلْتُ عَنْهُ الزُّهْرِيَّ فَقَالَ حَدَّثَنِي عَبْدُ الرَّحْمَنِ الأَعْرَجُ أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ شَرُّ الطَّعَامِ طَعَامُ الْوَلِيمَةِ ‏.‏ ثُمَّ ذَكَرَ بِمِثْلِ حَدِيثِ مَالِكٍ.
