How is the Zakat calculated on land purchased with the intention of trading it, if its current value is unknown? And is Zakat obligatory on inherited land registered in the name of another person, and how is its value calculated in this case?

Land purchased with the intention of trade is considered a trade asset subject to Zakat (definition), which is assessed annually based on its value. Its value can be determined by consulting experts, real estate offices, or by appointing someone for this purpose, while being diligent in paying Zakat as it is one of the pillars of Islam. As for inherited land, there is no Zakat due on it, because the condition of purchasing it for a consideration and with the intention of trade at the time of purchase is not met.
