Credit Transaction and Paying its Price from the Money that its Khums has not been Paid
Issue No. 1481- If a person purchases a commodity on credit, and after the transaction, pays its price from the money whose due khums has not been paid, the transaction will be in order and he is permitted to use it. However, since he has given the seller from the money on which khums is due, he will remain indebted to him for the amount of one fifth of that money. In case that amount is in the hand of the seller, the Mujtahid or his representative will get the same money, and if the same money is not available any more, the Mujtahid will demand its equivalent from either the seller or the buyer.
