What is the ruling on purchasing a product from a website, then returning it to get the price refunded along with an agreed-upon profit from the product owner in exchange for marketing it, knowing that there is a dedicated portion of this profit for Allah?

The seller's benefit from a fictitious sale in e-marketing and advertising is forbidden due to the deception and fraud it entails for shoppers, based on the Prophet's (PBUH) saying: "He who deceives us is not one of us." It is not permissible to take a wage for this work, because when Allah forbids something, He also forbids its price, and because forbidden benefits cannot be compensated.
