عَنْ مَالِكٍ أَنَّهُ بَلَغَهُ أَنَّ أَبَا هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللّٰهِ صَلَّى اللّٰهُ عَلَيْهِ وَسَلَّمَ
لِلْمَمْلُوكِ طَعَامُهُ وَكِسْوَتُهُ بِالْمَعْرُوفِ وَلَا يُكَلَّفُ مِنَ الْعَمَلِ إِلَّا مَا يُطِيقُ (Muwaṭṭaʾ Mālik)
Translation: An enslaved person is to receive suitable food and clothing and must not be assigned work beyond his ability.
1. Mamlūk: An enslaved person in the historical setting, not an ordinary employee.
