Nisab in dollars and other currencies

Q: What is the Nisab (minimum amount on which Zakah is due) in dollars?

A: The amount of Nisab in dollars and other paper money currencies is equal to the value of twenty Mithqals (4.68 grams) of gold, or one hundred and forty Mithqals of silver in dollars, if you have the Nisab in money (dollars or other currencies) at the time the Zakah is due. The share given to the poor has to be the value of one of those Nisabs, taking into account the difference in the values of currencies due to changes in time and place.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
