Q 1:
I have a taxi that transfers people between cities; should I pay Zakah (obligatory charity) for it?
A:
This car is similar to a house prepared for renting. If a house is rented, then Zakah becomes due in its revenue after the passage of a full lunar year of its renting. (Part No. 9; Page No. 352) Likewise, Zakah is due in what is saved of its revenue after the passage of a full lunar year. You are not required to pay Zakah on the value of this car.
