What is the amount of zakah on gold, silver, and trade goods?

Question : What is the amount of zakah on gold, silver, and trade goods?

Answer : The amount of zakah is one-tenth of a quarter, that is, one out of forty. Is that clear? The zakah on gold, silver, and trade goods is one-tenth of a quarter, that is, one out of forty. How much is it in forty thousand? Forty thousand dirhams. One thousand out of four hundred, my brothers. May Allah hasten His pleasure with you. How much is it in forty thousand? One thousand riyals. How does it become four hundred thousand? Four hundred thousand, one hundred riyals. How? Okay, let us repeat the example a second time. If it is four hundred thousand, correct, but how much is it in four hundred thousand? One thousand riyals in four hundred thousand. Ten thousand. Okay, how much is it in forty riyals? That is wrong. How much is it in forty riyals? There is nothing in it because it has not reached the nisab (minimum threshold for zakah). Is that clear? How much is it in four hundred riyals? It is equivalent to one hundred riyals of silver. It reaches the nisab. Four riyals, because fifty-six riyals of silver, how much is that in four riyals?
Ten riyals. Okay, if the zakah, and praise be to Allah, is a small portion, yet it brings the great reward that you heard about, and safety from the punishment, and benefit to your brothers, and blessing in your wealth, how can you evade the zakah? It has this great virtue, and it is a small portion of the wealth. No sane person can possibly evade it at all.
