Question: He is confused about buying a property by renting it, ending with ownership?
Response: No, no, no! Do not [enter into a contract to] buy [a property] by renting it, culminating with ownership. There is no [contract combining] renting and selling or anything; it is not permissible to combine two differing contracts [into one].
