Zakah on a sum saved for several years

The questioner:
The Shaykh’s case: He informed him that he has five thousand riyals with him, a lunar year has passed over them, and he paid the zakah on the wealth, which was one hundred and twenty-five riyals, and a second lunar year has passed over the same amount.

The Shaykh:
Or the amount.

The questioner:
Okay.

The Shaykh:
Five thousand, five thousand is subject to a quarter of a tenth. A quarter of a tenth. The tenth of five thousand is five hundred riyals. Half of five hundred. Two hundred and fifty. Half of two hundred and fifty, right? One hundred and twenty-five. One hundred and twenty-five. This is the obligatory amount. The obligatory amount is one hundred and twenty-five. And how much did he say he paid? One hundred and fifty. Yes, that is fine. Yes.

The questioner:
And there was no increase in it; a lunar year passed over it, and he paid the zakah on the wealth in the amount of twenty-five riyals, and a second lunar year passed over the same amount,

The Shaykh:
which is what increased.

The questioner:
And.

The Shaykh:
If it did not increase and it is less than the zakah of last year, then you pay the zakah from the remainder, only from the remainder that exists. If one thousand remained and you paid one hundred and twenty-five from it this year, then it is no longer one thousand; it became nine hundred and seventy-five. It became eight hundred and seventy-five. You pay zakah on eight hundred and seventy-five next year, and whatever remains, you pay zakah on the reduced amount, and so on. Therefore, the Lawgiver forbids freezing wealth because zakah consumes it in this way. The Lawgiver forbids freezing wealth and commands investing it in what is lawful and growing it so that zakah does not consume it. Yes.
