Malik related to me that he heard that Abu Hurayra said that the Messenger of Allah ﷺ said, "A slave has his food and clothing in the normal manner, and he is only obliged to do such work as he is capable of doing."
قَالَ قَالَ رَسُولُ اللَّهِ ﷺ لِلْمَمْلُوكِ طَعَامُهُ وَكِسْوَتُهُ بِالْمَعْرُوفِ وَلاَ يُكَلَّفُ مِنَ الْعَمَلِ إِلاَّ مَا يُطِيقُ
