Abu Shu'bah narrates: A man came to Abu Dharr (may Allah be pleased with him) and offered him some money. Abu Dharr (may Allah be pleased with him) said: "We have goats which we milk, donkeys which carry our loads, a freed slave-woman who serves us, and a cloak left over besides our clothes. I fear that I may be called to account for what is surplus."
