Muwatta 1984

Malik says: as for goods sold on which the buyer has done nothing, except that the goods have perished and their price has risen, and their owner wants them, while the creditors want to keep them: the creditors have the choice between giving the owner of the goods the price for which he sold them, without reducing it at all, and handing him over his goods. If the price of the goods has fallen, the seller has the choice: if he wishes, he takes his goods and has no claim on any of the debtor's property; that is his right. If he wishes to be one of the creditors, sharing in proportion to his claim, and does not take his goods, that is his right. ¹
