Al-Ma'rur ibn Suwayd said, "I saw Abu Dharr wearing a robe and his slave was also wearing a robe. We asked him about that and he said, 'I insulted a man and he complained about me to the Prophet, may Allah bless him and grant him peace, and the Prophet, may Allah bless him and grant him peace, said to me, 'Did you insult him by his mother?' 'Yes,' I replied. He said, 'Your brothers are your property. Allah has put them under your authority. If someone has his brother under his authority, he should feed him from what he eats and clothe him from what he wears and not burden him with anything that will be too much for him. If you burden him with what will be too much for him, then help him.'"
