What is the ruling on zakat for money in the following cases: money that remained for half a year and was then used to purchase apartments for children; owned apartments that are rented out; owned apartments that are not rented out; and installments for an apartment that has not yet been received and is being paid for in installments?

Firstly: Money that has not completed a full lunar year (hawl) and was used to purchase apartments is not subject to zakat.

Secondly: Apartments that you own and do not rent out are not subject to zakat.

Thirdly: For rented apartments, zakat is due on their rental income if it reaches the نصاب (minimum threshold) and a full lunar year (hawl) has passed over it.

Fourthly: Opinions differ regarding deducting debt from zakat, and the most preponderant view is that debt should not be deducted from zakat.
