Paying zakaat on behalf of one's wife
Q: One year ago I got married. My wife was gifted with gold from her parents and my parents too. The gold qualifies the "nisab" amount. She is a domestic wife. First I planned to pay zakaat on the the gold in a lumpsum after one year. But being a salaried person I could not do it as per my planning. Now I intend to pay a certain portion of zakaat from my salary each month. Please guide me on how should I calculate zakaat. For example on completion of the first year, the rate of gold was different from now.
