Torah's Stance on Selling Counterfeit Goods

Question: What does the Torah say about selling counterfeit items and misrepresenting merchandise? Answer: The Torah strictly prohibits selling counterfeit items or misrepresenting merchandise, commanding us to avoid anything associated with falsehood, including selling fakes as genuine, used as new, or misrepresenting quality. Deceiving customers, even if the product functions, constitutes geneivat da'at—a serious sin according to the Rambam. The Torah equates dishonest business with idol worship and states that such practices are detestable to Hashem, strengthening our enemies like Amalek. No positive outcome can derive from deceit in business.
