What is the legal status of transactions (buying and selling) conducted by an improvident person after a restriction has been imposed?

Primary text

If the improvident person sells or buys after the restriction has been imposed, the transaction is invalid (Fāsid). The ruler must reclaim any sold property and return the purchase price if it remains. If the improvident person destroys the property or it perishes while in his possession, the loss falls upon the buyer, and the improvident person bears no liability.
