Q: I live in Saudi Arabia. The price per gram of gold is 200 Saudi Riyals. How do I calculate the zakaat amount for gold my wife has?
A: 200 multiplied by the weight of the gold. Then 2.5% (40th) of the value must be given in Zakaat.
Example: 200 x 80 grams of gold = 16 000. 2.5% will be 400.
If the gold and your wife are with you in Saudi, then pay according to this price. If she is in another country, then the price in that country.
