Mishkat al-Masabih 13 Marriage كتاب النكاح 136

وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «شَرُّ الطَّعَامِ طَعَامُ الْوَلِيمَةِ يُدْعَى لَهَا الْأَغْنِيَاءُ وَيُتْرَكُ الْفُقَرَاءُ وَمَنْ تَرَكَ الدَّعْوَةَ فَقَدْ عَصَى الله وَرَسُوله»

Abu Huraira reported God’s Messenger as saying, “The worst kind of food is that at a wedding-feast to which the rich are invited and from which the poor are left out. If anyone rejects an invitation he has disobeyed God and His Messenger.” (Bukhari and Muslim.)
