Sahih Muslim 1661 c

At Ar-Rabadha I met Abu Dhar who was wearing a cloak, and his slave, too, was wearing a similar one. I asked about the reason for it. He replied, "I abused a person by calling his mother with bad names." The Prophet (ﷺ) said to me, 'O Abu Dhar! Did you abuse him by calling his mother with bad names You still have some characteristics of ignorance. Your slaves are your brothers and Allah has put them under your command. So whoever has a brother under his command should feed him of what he eats and dress him of what he wears. Do not ask them (slaves) to do things beyond their capacity (power) and if you do so, then help them.' "

I saw Abu Dhar Al-Ghifari wearing a cloak, and his slave, too, was wearing a cloak. We asked him about that (i.e. how both were wearing similar cloaks). He replied, "Once I abused a man and he complained of me to the Prophet (ﷺ) . The Prophet (ﷺ) asked me, 'Did you abuse him by slighting his mother?' He added, 'Your slaves are your brethren upon whom Allah has given you authority. So, if one has one's brethren under one's control, one should feed them with the like of what one eats and clothe them with the like of what one wears. You should not overburden them with what they cannot bear, and if you do so, help them (in their hard job).

I saw Abu Dhar wearing a Burd (garment) and his slave too was wearing a Burd, so I said (to Abu Dhar), "If you take this (Burda of your slave) and wear it (along with yours), you will have a nice suit (costume) and you may give him another garment." Abu Dhar said, "There was a quarrel between me and another man whose mother was a non-Arab and I called her bad names. The man mentioned (complained about) me to the Prophet. The Prophet (ﷺ) said, "Did you abuse so-and-so?" I said, "Yes" He said, "Did you call his mother bad names?" I said, "Yes". He said, "You still have the traits of (the Pre-lslamic period of) ignorance." I said. "(Do I still have ignorance) even now in my old age?" He said, "Yes, they (slaves or servants) are your brothers, and Allah has put them under your command. So the one under whose hand Allah has put his brother, should feed him of what he eats, and give him dresses of what he wears, and should not ask him to do a thing beyond his capacity. And if at all he asks him to do a hard task, he should help him therein."

We went to Abu Dharr (Ghifari) in Rabadha and he had a mantle over him, and his slave had one like it. We said: Abu Dharr, had you joined them together, it would have been a complete garment. Thereupon he said: There was an altercation between me and one of the persons among my brothers. His mother was a non-Arab. I reproached him for his mother. He complained against me to Allah's Messenger (ﷺ). As I met Allah's Messenger (ﷺ) he said: Abu Dharr, you are a person who still has (in him the remnants) of the days (of Ignorance). Thereupon I said: Allah's Messenger (ﷺ) , he who abuses (other) persons, they abuse (in return) his father and mother. He (the Prophet) said: Abu Dharr, you are a person who still has (the remnants) of Ignorance in him They (your servants and slaves) are your brothers. Allah has put them in your care, so feed them with what you eat, clothe them with what you wear. and do not burden them beyond their capacities; but if you burden them (with an unbearable burden), then help them (by sharing their extra burden).

"Allah has made some of your brothers as slaves under your care. So whoever has his brother under his care, then let him feed him from his food, and let him clothe him from his clothes. And do not give him a duty that he cannot bear, and if you give him a duty he cannot bear, then assist him with it."

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.
