Ibrahim (Nakhai, may Allah have mercy on him) narrated: The wife of Abdullah (may Allah be pleased with him) came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah! I have jewelry and my orphan nephews are under my care, so can I spend the zakat of my jewelry on them? The Prophet (peace and blessings be upon him) said: "Yes."
