What is the amount of zakat due on: 100 grams of gold that have been held for eight years, and another 100 grams that have been held for five years (knowing that some of the gold is used for adornment); and on land that was purchased nine years ago for trade and sold four years ago, and another piece of land purchased ten years ago for investment and has not been sold; and on a shop that was purchased three years ago and is rented out periodically; and are unpaid debts deductible from the zakatable wealth?

Repentance is obligatory for delaying Zakat after it becomes due. A Muslim must hasten to pay Zakat when its time arrives. Zakat is obligatory on gold if it reaches 85 grams or more and a full year has passed on it, and its amount is a quarter of a tenth (2.5%). The amount of Zakat due on deferred gold differs according to the sayings of scholars: some say it is obligatory on the asset itself, while others say it is obligatory as a liability on the payer (in their accountability). The opinion that Zakat is obligatory as a liability is more cautious, clears one's accountability better, and is more beneficial for the poor. According to this opinion, the Zakat on 100 grams for eight years is 20 grams, and for five years, it is 12.5 grams. As for gold used for adornment (wearing), scholars have differed regarding the obligation of Zakat on it, and the opinion that Zakat is obligatory on it is more cautious and clears one's accountability better.
