What is the ruling on electronic mediation in purchasing a product from the Internet and shipping it to the one who requested it for a sum of money, where the mediator offers to provide the product at a price that includes its cost, shipping, and his profit?

There is no harm in the transaction if the sales contract is concluded after the second party has taken possession of the commodity. Anything before that is a promise and a request for a service, not the establishment of a sales contract before taking possession. There is no harm in creating a website for mediation and bringing the two parties to the contract together for a known commission taken from both or one of them, with the knowledge of the one from whom it is taken. The website owner must guide and advise both parties regarding the Sharia-compliant regulations for the validity of the contract.
