Muwatta 1981

Malik says of a man who sold goods to another, who became insolvent: if the seller finds any of his goods themselves, he takes them. If the buyer sold some of them and dispersed them, the owner of the goods has a better right to them than the creditors. The fact that the buyer dispersed some of them does not prevent the owner from taking what he finds itself. If the seller collected something of the buyer's price, and then wishes to return it and take back what he finds of his goods, and what he did not find he shares with the creditors, that is his right. ¹
