Hadith 4244
Sayyiduna Jabir (may Allah be pleased with him) narrates: A man submitted, "O Messenger of Allah (peace and blessings be upon him)! With what should I discipline the orphan child under my care?" The Noble Prophet (peace and blessings be upon him) said: "With that which you discipline your own son. Do not try to protect your wealth through the wealth of the orphan under your care, and do not try to increase your wealth through it."
