مشكاة المصابيح — حديث #٣٩٧٧١

He said, I used to wear gold Awazah (the name of a kind of ornament). قلت يوما يا رسول الله! The gold ornaments and what will be considered as accumulated goods? (Which is feared in the Qur'an?) He said, That which fulfills the Nisab and gives Zakat on it. يصبح مقدسا. Then it is not counted among the accumulated wealth. (مالك، أبو داود) [1]
