Calculating zakaat

Zakaat on Kruger coins

Q: Please advise me on whether zakat is payable on the selling price of a kruger coin or on the market value of an ounce of gold. The selling value of a kruger coin is more than the value of an ounce of gold although the kruger coin weighs an ounce.

When is zakaat due?

Q:

  1. When must I pay my zakaat? Is it during a specific month or at any time?
  2. When working out my zakaat, do I only consider the gold/silver and cash that I have at that specific time or does it work in cycles?

Zakaat on dollars

Q: In the country I stay, there is a big difference in the black dollar and official dollar rate. The dollar in this country is not the local currency. When I change dollars, I change on the black market because of the rate being higher. I normally take out my zakaat in the local currency. On the dollars that I have, should I take out my zakaat on the black market rate or on the official rate?
