Yahya related to me from Malik from Abd ar-Rahman ibn al-Qasim from his father that A'isha, the wife of the Prophet, may Allah bless him and grant him peace, used to look after the orphaned daughters of her brother in her house. They had jewellery (which they wore) and she did not take zakat from this jewellery of theirs.
Muwatta Malik Book 17, Hadith 12
← Previous Hadith Malik said, "The position which we are agreed upon, and which I have heard the people of knowledge mentioning, is that rikaz refers to treasure which has been found which was buried during the jahiliyya, as long as neither capital is required, nor expense, great labour or inconvenience incurred in recovering it. If capital is required or great labour is incurred, or on one occasion the mark is hit and on another it is missed, then it is not rikaz."

Muwatta Malik Book 17, Hadith 11 Next Hadith → Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to adorn his daughters and slave-girls with gold jewellery and he did not take any zakat from their jewellery.

Malik said, "Anyone who has unminted gold or silver, or gold and silver jewellery which is not used for wearing, must pay zakat on it every year. It is weighed and one-fortieth is taken, unless it falls short of twenty dinars of gold or two hundred dirhams of silver, in which case there is no zakat to pay. Zakat is paid only when jewellery is kept for purposes other than wearing. Bits of gold and silver or broken jewellery which the owner intends to mend to wear are in the same position as goods which are worn by their owner - no zakat has to be paid on them by the owner."

Malik said, "There is no zakat (to pay) on pearls, musk or amber."
