Is it obligatory to pay Zakat on jewelry again if the husband paid it on behalf of his wife without her knowledge?

The majority of scholars do not obligate zakat on jewelry used for permissible adornment, although paying it is more cautious to avoid disagreement. The intention of the zakat payer is a condition for the validity of zakat; therefore, paying the zakat on your wife's jewelry on her behalf without her knowledge is not valid.
