Is it permissible for the importer to sell the amount of a bank transfer to a third party, whereby they agree on an exchange rate between the bank rate and the parallel market rate, and the third party pays the bank and receives the amount sent to the exporter on behalf of the importer, due to the importer's lack of sufficient funds to transfer again?

For the currency exchange process with the bank to be permissible, the currencies must be exchanged hand-to-hand in the contracting session, and the amount must be equal to the amount in the other currency. If any of these conditions are not met, it is impermissible. As for selling a debt to someone other than the debtor, it is not permissible except under five conditions: that the debt is not food, that the debtor is present and acknowledges the debt, that the debt is sold for a different currency, that the sale is not intended to harm the debtor, and that the price is cash. If any of these conditions are not met, selling the debt is impermissible.
