Ibrahim (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: The nephews of Abdullah are under my care. If I spend charity from my wealth on them, will that suffice for me? The Prophet (peace and blessings be upon him) said: "Yes."
