What is the ruling on eating meat that a husband bought with usury, without the seller's intention?

The method of purchase by card, how installments are calculated, and the nature of the card were not clarified, and these are matters that determine the ruling. If the seller increased the price of the meat because it is being paid in installments, this is not usury, as he has the right to sell his goods at the price he chooses. However, if he had agreed not to increase the price and then took an increase, he must return it. The meat is halal in all circumstances.
