Must the wife add the price of a car sold five years ago and an unspecified, untracked deferred mahr to her ornamental gold for the purpose of calculating Zakat? And is it sufficient for the husband to pay Zakat on his wealth on behalf of his wife's wealth in his possession? And must he pay Zakat on the gold if it reaches the nisab by adding these funds, or Zakat on the price of the car and the deferred mahr again?

The majority of scholars hold that women's jewelry intended for adornment is not subject to zakat (definition), and this is the most preponderant opinion. Cash money is added to gold to reach the nisab (definition) if the gold alone does not meet it, and zakat becomes obligatory on the entire amount after the passing of a hawl (lunar year). The deferred dower (mu'akhkhar as-sadaq) is treated like a debt. Zakat is not obligatory on the value of a car as long as it is not intended for trade, but rather on its price if a hawl passes on it. For the years during which the husband was unable to pay the deferred dower, zakat is not obligatory for those years; if he receives it, he pays zakat on it only once for the year of receipt. The fundamental principle is that the wife is the one who pays the zakat on her wealth, and it is permissible for the husband to be entrusted with this, provided she is aware and he intends to pay the zakat on her behalf.
