Q 6:
If I own a building or hospital and use them as a source of income, do I have to pay Zakah (obligatory charity) on the value of the buildings or the revenue?
A:
If the situation is as you have mentioned, then Zakah has to be paid on the revenue when it reaches the Nisab (the minimum amount on which Zakah is due) and remains in your possession for one year. It should not be paid on the value of the building or the hospital itself. This is the same as the case of Zakah on farm lands where Zakah is not paid on the value of the farm itself but on the crops, such as grains or fruits.
