Ma’rur b. Suwaid said:

We called on Abu Dharr at al-Rabadhah. He wore a cloak and his slave also wore a similar one. We said; Abu Dharr! If you took the cloak of your slave and combined it with your cloak, so that it could be a part of garments (hullah) and clothed him in another garment, (it would be better). He said; I heard the Messenger of Allah ﷺ say; They are your brethren. Allah has put them under your authority; so he who has his brother under his authority must feed him from what he eats and clothe him with what he wears, and not impose on him work which is too much for him, but if he does so, he must help him.

Abu Dawud said: Ibn Numair transmitted it from al-A'mash in a similar way.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا عِيسَى بْنُ يُونُسَ، حَدَّثَنَا الأَعْمَشُ، عَنِ الْمَعْرُورِ بْنِ سُوَيْدٍ، قَالَ دَخَلْنَا عَلَى أَبِي ذَرٍّ بِالرَّبَذَةِ فَإِذَا عَلَيْهِ بُرْدٌ وَعَلَى غُلاَمِهِ مِثْلُهُ فَقُلْنَا يَا أَبَا ذَرٍّ لَوْ أَخَذْتَ بُرْدَ غُلاَمِكَ إِلَى بُرْدِكَ فَكَانَتْ حُلَّةً وَكَسَوْتَهُ ثَوْبًا غَيْرَهُ قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ
" إِخْوَانُكُمْ جَعَلَهُمُ اللَّهُ تَحْتَ أَيْدِيكُمْ فَمَنْ كَانَ أَخُوهُ تَحْتَ يَدَيْهِ فَلْيُطْعِمْهُ مِمَّا يَأْكُلُ وَلْيَكْسُهُ مِمَّا يَلْبَسُ وَلاَ يُكَلِّفْهُ مَا يَغْلِبُهُ فَإِنْ كَلَّفَهُ مَا يَغْلِبُهُ فَلْيُعِنْهُ " . قَالَ أَبُو دَاوُدَ وَرَوَاهُ ابْنُ نُمَيْرٍ عَنِ الأَعْمَشِ نَحْوَهُ .
