Alms Tax: Zakat on Gold and Silver Coins Used as Ornaments
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 1916
In the event that minted gold and silver coins that are used by women as ornaments are used prevalently in transactions – meaning that gold and silver are used as money in transactions – then based on obligatory precaution, zakat is obligatory on them. However, if they are not used prevalently in transactions, then zakat is not obligatory on them.
