Sahih al-Bukhari, Hadith 5460 ⓘ
Narrated.Abu Huraira: The Prophet said, "When your servant brings your food to you, if you do not ask him to join you, then at least ask him to take one or two handfuls, for he has suffered from its heat (while cooking it) and has taken pains to cook it nicely."
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنْ مُحَمَّدٍ ـ هُوَ ابْنُ زِيَادٍ ـ قَالَ سَمِعْتُ أَبَا هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِذَا أَتَى أَحَدَكُمْ خَادِمُهُ بِطَعَامِهِ، فَإِنْ لَمْ يُجْلِسْهُ مَعَهُ فَلْيُنَاوِلْهُ أُكْلَةً أَوْ أُكْلَتَيْنِ، أَوْ لُقْمَةً أَوْ لُقْمَتَيْنِ، فَإِنَّهُ وَلِيَ حَرَّهُ وَعِلاَجَهُ " .
