Sunan Ibn Majah, Book 29, Hadith 3415 (In-Book) ⓘ

It was narrated from Abu Hurairah that the Messenger of Allah said: “When the slave of anyone of you brings his food to him, for which he (the slave) has worked hard and endured heat, let him invite him to eat with him, and if he does not do that then let him take a morsel and put it in his hand.”

حَدَّثَنَا عِيسَى بْنُ حَمَّادٍ الْمِصْرِيُّ، أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنْ جَعْفَرِ بْنِ رَبِيعَةَ، عَنْ عَبْدِ الرَّحْمَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏ "‏ إِذَا أَحَدُكُمْ قَرَّبَ إِلَيْهِ مَمْلُوكُهُ طَعَامًا قَدْ كَفَاهُ عَنَاءَهُ وَحَرَّهُ فَلْيَدْعُهُ فَلْيَأْكُلْ مَعَهُ فَإِنْ لَمْ يَفْعَلْ فَلْيَأْخُذْ لُقْمَةً فَلْيَجْعَلْهَا فِي يَدِهِ ‏" ‏ ‏.‏
