Lady Asma bint Yazid (may Allah be pleased with her) says: My maternal aunt and I entered upon the Noble Prophet (peace and blessings be upon him), and we were wearing gold bangles. He (peace and blessings be upon him) said: "Do you pay zakat on them?" We said: "No." He (peace and blessings be upon him) said: "Do you not fear that Allah Almighty may make you wear two bangles of fire in exchange for them? Pay their zakat."
