The ruling on the zakah of a car, worn gold, and a rented-out house

Question:
The questioner asks: Is there zakah on a car, on the wife’s worn gold, and on a rented-out house?

Answer:
All of these matters, if they are for personal use, have no zakah. This applies to a house used for residence or for renting out, as well as a car used for riding or for renting out. There is no zakah on these items. However, the one who rents out a house owes zakah on the rent if it reaches the nisab (minimum threshold) and a lunar year has passed over it.
As for jewelry, specifically the jewelry a woman wears, this is a matter of scholarly disagreement. Some scholars, who are the majority, hold that there is no zakah on it because it is not for increase or trade, but rather for use and wearing, so there is no zakah on it. A group of scholars hold that zakah is obligatory on it based on the general texts. In any case, the one who pays zakah on it is being more cautious, thereby clearing his conscience and avoiding the disagreement.
