Abu Dawud Book 3, Hadith Number 1558.

Narated By Abdullah ibn Amr ibn al-‘As : A woman came to the Apostle of Allah (PBUH) and she was accompanied by her daughter who wore two heavy gold bangles in her hands. He said to her: Do you pay zakat on them? She said: No. He then said: Are you pleased that Allah may put two bangles of fire on your hands?

Thereupon she took them off and placed them before the Prophet (PBUH) saying: They are for Allah and His Apostle.
