Ruling Regarding Khums on the Wealth Acquired from a Person who Believes in Khums
Issue No. 1485- If we know that a person, despite believing in paying khums, does not pay it, while we are not sure whether the property he has given to us has been liable to khums or not, (for example, he is likely to have inherited some property or he may have received a loan and we consider it probable that the thing he has given us is from that property), there would be no problem in using such a property and it is not necessary to pay its khums. It is also permissible to accept the invitation of such people or offer prayer in their houses insofar as we do not know that the food he has prepared or his house that has been purchased is from the money which he has not paid its khums.
