The Zakah of Real Estate Sold on Installments and Debts

Question:
The questioner says: A man has real estate that he sells to people on installments, and he has nothing in his hand right now, and a lunar year has passed over him. How does he pay his zakah? And if he has money he borrowed from another person, does he pay zakah on it?

Answer:
Zakah is obligatory on what you have, on the money you own. Even if you borrowed it from a person, it is your property, so you pay zakah on it. You pay zakah on what is with you, in your hand, and in your possession.
As for the debts you have with people, these fall into two categories. The first category is what you are confident of receiving because it is in the hand of a solvent person who is willing to pay. Whenever you demand it or its due date arrives, he will give it to you. You pay zakah on this every year, whether you receive it or not, because it is considered as being in your hand.
The second category is debts owed by those who are unable to pay, where you do not know if they can pay or not, or by those who delay payment, where you do not know if you will get your right from them or not. Zakah is not obligatory on these unless you receive them. If you receive them, you pay zakah on them for one year only. Yes.
