Brief Explanation
Benefits: … To sell over someone’s sale means that when a seller and a buyer are engaged in a transaction, both appear to be consenting, and the contract is about to be finalized, then a third person intervenes and, by offering a higher price, inclines the owner towards himself. Through this action of the third person, enmity and discord will increase among Muslims; therefore, the Prophet sallallahu alayhi wa sallam prohibited doing so.
