How to pay zakah on a debt

Question:
He has a debt owed to him by one of his colleagues, and several years have passed; and now I am asking about the zakah on this debt and this person who has not repaid this debt?

Answer:
Answer: If you are confident that this debt will come to you, then you pay zakah on it every year; because it is in the ruling of what is in your hand. As for if the debt is on someone who is unable to pay and you do not know whether it will be obtained or not, or if it is on someone who is delaying and you do not know whether he will give you your right or not, then you do not pay zakah on it until you receive it, and only for the year in which you received it.
