“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.”  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَحَدُكُمْ قَرَّبَ إِلَيْهِ مَمْلُوكُهُ طَعَامًا قَدْ كَفَاهُ عَنَاءَهُ وَحَرَّهُ فَلْيَدْعُهُ فَلْيَأْكُلْ مَعَهُ فَإِنْ لَمْ يَفْعَلْ فَلْيَأْخُذْ لُقْمَةً فَلْيَجْعَلْهَا فِي يَدِهِ  

[Machine] And when one of you's servant makes food, he should let him eat it and share in his difficulty, and if he does not let him eat it, he should give him a portion of it.  

وَإِذَا صَنَعَ خَادِمُ أَحَدِكُمْ طَعَامًا فَوَلِيَ حَرَّهُ وَمَشَقَّتَهُ فَلْيَدْعُهُ فَلْيَأْكُلْ مَعَهُ فَإِنْ لَمْ يَدْعُهُ فَلْيُنَاوِلْهُ مِنْهُ
