Amr bin Shu'ayb reports from his father, from his grandfather (may Allah be pleased with him), that a man came to the Messenger of Allah (peace and blessings be upon him) and said: "I am poor and have nothing, and I have an orphan (in my care)." He (peace and blessings be upon him) said: "Eat from your orphan's wealth without extravagance, without hastening, and without accumulating."
