Is zakat due on gold savings every year, or just once in a lifetime, as one of the imams in India stated?

Scholars have unanimously agreed that zakat (definition) recurs annually on wealth such as gold and silver, with the exception of crops and fruits, on which zakat is due only once. The evidence for this is the practice of the Muslim community since the time of the Prophet, peace and blessings be upon him, who used to send collectors to gather zakat on all existing zakatable wealth. What has been said about zakat on gold not recurring annually indicates the ignorance of its proponent, who should refer to the statements of scholars and not rush into issuing fatwas.
