Selling something to a Muslim does not Abandon Paying Khums
Issue No. 1564- If a dhimmī sells a piece of land purchased from a Muslim, to another Muslim, he is not absolved from the responsibility of paying khums. The same goes, as an obligatory precaution, if he (the dhimmī) dies and a Muslim inherits that land from him. And if at the time of purchasing land the dhimmī stipulates that he will not pay khums or that the payment of khums will be the responsibility of the seller, the condition imposed by him is not valid, and he should pay khums. In case however, he lays down the condition that the seller should pay khums “on his behalf” it is necessary for the seller to act according to this condition.
