What is the ruling of the Sharia on a fatwa that claims that zakat on land purchased for investment is only obligatory once, upon its sale, and not every year, and that it is like "durable goods" and not like "trade goods"?

If you have bought land with the intention of investment, then if you intend to lease it and benefit from its returns, there is no zakat due on it. However, if you are waiting for its price to increase in order to sell it, the majority of jurists hold the view that zakat is obligatory on its value every Hijri year, and this is the more cautious opinion. The Malikis hold the view that zakat is obligatory only upon sale for one year, and they differentiate between a hoarding merchant (who waits for the commodity) and a circulating merchant (who sells continuously). The Sheikh's fatwa which exempts this land from zakat every year, based on the premise that it is a durable good, is incorrect, as durable goods that are traded are subject to zakat every year. It is permissible to adopt the Maliki opinion on this issue, but the better and more cautious approach is to adopt the opinion of the majority.
