Sahih Muslim 1661 c
Ma'rur b. Suwaid reported:
I saw Abu Dharr wearing clothes, and his slave wearing similar ones. I asked him about it, and he narrated that he had abused a person during the lifetime of Allah's Messenger (may peace be upoe. him) and he reproached him for his mother. That person came to Allah's Apostle (ﷺ) and made mention of that to him. Thereupon Allah's Apostle (ﷺ) said: You are a person who has (remnants of) Ignorance in him. Your slaves are brothers of yours. Allah has placed them in your hand, and he who has his brother under him, he should feed him with what he eats, and dress him with what he dresses himself, and do not burden them beyond their capacities, and if you burden them, (beyond their capacities), then help them.
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ - وَاللَّفْظُ لاِبْنِ الْمُثَنَّى - قَالاَ حَدَّثَنَا مُحَمَّدُ، بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ، عَنْ وَاصِلٍ الأَحْدَبِ، عَنِ الْمَعْرُورِ بْنِ سُوَيْدٍ، قَالَ رَأَيْتُ أَبَا ذَرٍّ وَعَلَيْهِ حُلَّةٌ وَعَلَى غُلاَمِهِ مِثْلُهَا فَسَأَلْتُهُ عَنْ ذَلِكَ قَالَ فَذَكَرَ أَنَّهُ سَابَّ رَجُلاً عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَعَيَّرَهُ بِأُمِّهِ - قَالَ - فَأَتَى الرَّجُلُ النَّبِيَّ صلى الله عليه وسلم فَذَكَرَ ذَلِكَ لَهُ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏
"‏ إِنَّكَ امْرُؤٌ فِيكَ جَاهِلِيَّةٌ إِخْوَانُكُمْ وَخَوَلُكُمْ جَعَلَهُمُ اللَّهُ تَحْتَ أَيْدِيكُمْ فَمَنْ كَانَ أَخُوهُ تَحْتَ يَدَيْهِ فَلْيُطْعِمْهُ مِمَّا يَأْكُلُ وَلْيُلْبِسْهُ مِمَّا يَلْبَسُ وَلاَ تُكَلِّفُوهُمْ مَا يَغْلِبُهُمْ فَإِنْ كَلَّفْتُمُوهُمْ فَأَعِينُوهُمْ عَلَيْهِ ‏"‏ ‏.‏
