What is the zakah of wealth, and is it permissible for me to appoint someone to pay the zakah on my behalf if I am not present?

Question:
What is the zakah of wealth? And is it permissible to appoint someone to pay the zakah on my behalf if I am not present?

Answer:
The zakah of wealth is the right that Allah the Exalted has made obligatory in it, which is paid in the channels of zakah that Allah specified in His saying: “Indeed, alms are for the poor and the needy…” to the end of the verse. The amounts of zakah vary according to the type of wealth. There are four types of wealth in which zakah is obligatory: what comes out of the earth, livestock, currency, and trade goods. These are the types of wealth subject to zakah, and each type has its own limits, amounts, and conditions for zakah to become obligatory.
The scholars (may Allah have mercy on them) in their books. Yes. May Allah reward you with good. Will you not be kind enough to explain that, even if only by saying that it appears he is not among those who read the books of the scholars?
As for the zakah of currency, if it reaches the nisab, the nisab of silver, or the nisab of gold, and the nisab of silver is one hundred and forty mithqals, and the nisab of gold is twenty mithqals, then if the gold or silver reaches the equivalent of this amount in any currency, whether it is metal currency or paper currency, the equivalent of this amount, then zakah is obligatory in it. If it reaches this amount, or more, zakah is obligatory in it. The amount of the nisab of zakah in our view is fifty-six Saudi Riyals, the well-known Saudi Riyal made of gold, or the equivalent in other types of currencies, meaning the equivalent of fifty-six Saudi Riyals. And the nisab of gold is eleven and a half Saudi pounds, or the equivalent of that amount in currency, meaning the equivalent of its exchange rate. On the condition that this wealth has been possessed for a lunar year. That is, if the currency reaches the nisab and a lunar year has passed over it, then zakah is obligatory in it by paying out one-tenth of a quarter. One-tenth of a quarter.
As for what comes out of the earth, this refers to grains and fruits. If what comes out of the earth is watered without assistance, watered by itself, watered by its roots, without cost, then it has one-tenth, one-tenth of what comes out, if it also reaches the nisab. And the nisab of grains is six hundred sa' (a dry measure of about 3 kg), or approximately the equivalent. The Messenger (peace and blessings be upon him) said: “There is no zakah on less than five wasq (a large measure of grain).” And the wasq is sixty sa'. If sixty is multiplied by five, do you know how much that is? Approximately three hundred. Correct. Yes. Three-quarters of a Prophetic measure. This is the nisab of grains. And the Prophetic sa' is equivalent to how many kilograms, if you please? Approximately three kilograms. So the nisab in kilograms is three hundred times three? Nine hundred kilograms. That is the nisab? Approximately, approximately. And if the grains and fruits are watered with salt and cost, whether by lifting machines or by canals, then it has half a tenth. As for trade goods, trade goods mean merchandise prepared for sale. These, if a lunar year passes over them, or a lunar year passes over their value, a lunar year passes over them themselves, or a lunar year passes over the value at which they were bought, then they are valued at the completion of the lunar year, meaning they are appraised and valued at what they are worth at the completion of the lunar year, and one-tenth of a quarter is paid out of the estimated value. What they were bought for is not considered; rather, their value at the completion of the lunar year, at what they are worth, is considered. And one-tenth of a quarter is paid out. As for livestock, which are camels, cattle, and sheep, these have conditions and characteristics, and the discussion of them is long. We will return to them in a future session, if Allah wills. If Allah wills.
