Conditions for the Obligation of Zakah on a Salary

Question:
May Allah reward you with good. This is your brother. He says: I used to work as a teacher in the Kingdom in a past year, from the ninth month to the seventh, meaning about ten months, and my salary was [amount] riyals. After the contract ended, I went down to my country with seven thousand five hundred riyals with me. After about two months, I needed that amount to build a house, and only a little remained from it. Is there zakah on that amount for me? And how is the zakah on a salary performed?

Answer:
If a year has passed over it and it is with you, then you pay zakah on it. If it reaches the nisab and a year—twelve months—has passed over it from the time you took possession of it, then zakah becomes obligatory on you by giving out a quarter of a tenth. But if what remained has not completed a hawl, and what remained is below the nisab, then there is no zakah on you, neither in what you spent, because the hawl did not complete over it, nor in what remained, because it is below the nisab, unless you have other wealth that you combine with it; in that case, you pay zakah on it together with that. Yes.
