Must I follow the Administration of Muslims of Uzbekistan in determining the Zakat nisab as $2700, or should I calculate my Zakat based on the value of 85 grams of pure gold, which is $5100?

The correct approach to estimating the nisab (minimum threshold for zakat) for paper currency is to base it on silver, not gold. This is more beneficial for the poor. The nisab for silver is 595 grams. Therefore, whoever possesses an amount of currency equivalent to this value is obligated to pay zakat. Jurists and Fiqh councils have affirmed this estimation, taking into consideration the welfare of the poor, such that trade goods are valued according to what is more beneficial for the poor, whether gold or silver.
