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 does not attend the feast to which he was invited, he has disobeyed Allah and His Apostle (may peace upon him). (Using translation from Abū Dāʾūd 3742)   

سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ «شَرُّ الطَّعَامِ طَعَامُ الْوَلِيمَةِ؛ يُدْعَى إِلَيْهَا الْأَغْنِيَاءُ وَيُتْرَكُ الْمَسَاكِينُ وَمَنْ لَمْ يَأْتِ الدَّعْوَةَ فَقَدْ عَصَى اللهَ وَرَسُولَهُ»  

[Machine] It is said that Abu Shuayb prepared a meal and sent it to the Prophet Muhammad, ﷺ , inviting him and five others. The Prophet asked, "Can I bring a sixth person with me?"  

يُقَالُ لَهُ أَبُو شُعَيْبٍ طَعَامًا فَأَرْسَلَ إِلَى النَّبِيِّ ﷺ تَعَالَ أَنْتَ وَخَمْسَةٌ فَقَالَ «أَتَأْذَنُ لِي فِي السَّادِسِ؟»  

[Machine] A man made food for the Prophet ﷺ and he sent a message to the Prophet ﷺ saying, "Come to me with five others." So the Prophet ﷺ sent a message to him saying, "Grant me permission for the sixth." Abu Abdur-Rahman said, "This is a mistake, and what came before it is correct."  

صَنَعَ رَجُلٌ لِلنَّبِيِّ ﷺ طَعَامًا فَأَرْسَلَ إِلَى النَّبِيِّ ﷺ أَنِ ائْتِنِي أَنْتَ وَخَمْسَةٌ قَالَ فَأَرْسَلَ إِلَيْهِ «أَنِ ائْذَنْ لِي فِي السَّادِسِ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ هَذَا خَطَأٌ وَالصَّوَابُ الَّذِي قَبْلَهُ
