Narrated Abu Huraira:

The Prophet ﷺ said, "When your servant brings your meals to you then if he does not let him sit and share the meals, then he should at least give him a mouthful or two mouthfuls of that meal or a meal or two meals, as he has prepared it."

حَدَّثَنَا حَجَّاجُ بْنُ مِنْهَالٍ، حَدَّثَنَا شُعْبَةُ، قَالَ أَخْبَرَنِي مُحَمَّدُ بْنُ زِيَادٍ، سَمِعْتُ أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ ﷺ
" إِذَا أَتَى أَحَدَكُمْ خَادِمُهُ بِطَعَامِهِ، فَإِنْ لَمْ يُجْلِسْهُ مَعَهُ، فَلْيُنَاوِلْهُ لُقْمَةً أَوْ لُقْمَتَيْنِ أَوْ أُكْلَةً أَوْ أُكْلَتَيْنِ، فَإِنَّهُ وَلِيَ عِلاَجَهُ ".
