FAIR TREATMENT H 1389 "I (Ma'arur the son of Su'ud) saw Abu Dharr wearing a cloak and I noticed that his servant wore one similar. I asked him about this and he explained that in the time of the Messenger of Allah, praise and peace be upon him, he had an argument with a man and humiliated him by making reference to his mother. Thereupon the Messenger of Allah, praise and peace be upon him, said to me (Abu Dharr) 'You still have traces of pre-Islamic disposition in you. Your servants are your brothers whom your Lord has placed under your authority. Whosoever has a brother under his authority should feed him out of that which he eats himself and should clothe him as he clothes himself. He should not assign a task to him which is beyond his strength but if you do so help him with it.'" R 1389 Bukhari and Muslim with a chain up to Ma'arur the son of Su'ud who related that the Messenger of Allah, praise and peace be upon him, said this.
1360- وعنِ المَعْرُورِ بن سُوَيْدٍ ، قَالَ : رَأيْتُ أَبَا ذَرٍ رضي الله عنه ، وَعَلَيهِ حُلَّةٌ وَعَلَى غُلاَمِهِ مِثْلُهَا، فَسَأَلْتُهُ عَنْ ذَلِكَ، فَذَكَرَ أنَّهُ قَدْ سَابَّ رَجُلاً عَلَى عَهْدِ رسول الله صلى الله عليه وآله وسلم ، فَعَيَّرَهُ بِأُمِّهِ ، فَقَالَ النبيُّ صلى الله عليه وآله وسلم : "إنَّكَ امْرُؤٌ فِيكَ جَاهِليَّةٌ هُمْ إخْوَانُكُمْ وَخَوَلُكُمْ جَعَلَهُمُ الله تَحْتَ أيديكُمْ ، فَمَنْ كَانَ أَخُوهُ تَحْتَ يَدِهِ ، فَلْيُطْعِمْهُ مِمَّا يَأكُلُ ، وَلْيُلْبِسْهُ مِمَّا يَلْبَسُ ، وَلاَ تُكَلِّفُوهُمْ مَا يَغْلِبُهُمْ ، فَإنْ كَلَّفْتُمُوهُمْ فَأَعِينُوهُمْ" متفقٌ عَلَيْهِ .
