The Amount of Zakah on a Deposited Sum

Question:
The woman had an account with al-Rashidun Company. Whenever al-Rashidun took from the account, and he took from it from time to time, sometimes estimating the balance and sometimes taking it, how is the zakah calculated from it? Knowing that the current balance is five thousand, what is the amount of her zakah?

Answer:
One quarter of a tenth, one quarter of a tenth, two and a half percent, two and a half percent. For example, five thousand: its tenth is five hundred, right? The tenth of five thousand is five hundred. Half of the tenth is two hundred and fifty. One quarter of the tenth is one hundred and twenty-five. Five thousand contains one hundred and twenty-five riyals.
As for the one who deposits a portion of his salary every month, the best is that he designates a specific month of the year in which he pays the zakah on the total amount until that month comes around in the following year, and then he pays the zakah on whatever has accumulated with him. By doing this, his obligation is discharged, if Allah wills. Yes.
