Marur reported,

I met Abu Dharr at Rabadhah, and he was wearing a fine garment, and his servant was wearing one just like it. I asked him about that, and he said, "I once exchanged insults with a man and reproached him about his mother."The Prophet ﷺ said to me, "Abu Dharr, did you reproach him about his mother? You are a man in whom there is still some of the ways of jahiliyyah. Your servants are your brothers whom Allah has placed under your authority. So whoever has his brother under his authority should feed him from what he eats, clothe him from what he wears, and not burden him with what overwhelms him. If you do burden him, then help him."

عن المعرور قال

لقيت أبا ذر بالربذة، وعليه حلة، وعلى غلامه حلة، فسألته ذلك فقال: إني ساببت رجلا فعيرته بأمه، فقال عن النبي ﷺ: ا أبا ذر، أعيرته بأمه؟ إنك امرؤ فيك جاهلية، إخوانكم خولكم، جعلهم الله تحت أيديكم، فمن كان أخوه تحت يده ليطعمه مما يأكل، ويلبسه مما يلبس، ولا تكلفوهم ما يغلبهم، فإن كلفتموهم فأعينوهم.
