The ruling on buying a car and selling it on installment without registering it in the buyer's name

Question:
Another person says: I buy cars and sell them on installment, but I buy them from the showroom owner and ask him not to write the car in my name until I sell it. Then the person who bought it goes to the showroom and has it written in his name, so that there are not two names on the registration. What is your Eminence's opinion on this transaction?

Answer:
This is not permissible. You must buy it completely, put the names on it, take possession of it, and hold it, and then sell it afterwards. The new one puts the second name on it, because you are the first buyer and he is buying from you. This is deception. So you must buy it completely until you take possession of it and hold it, and then sell it afterwards. The Prophet (peace and blessings be upon him) said: "Do not sell what you do not have," and he said: "It is not permissible to combine a loan with a sale, nor to sell in a place where you have not taken possession of it first." And if you have taken possession of it and it has become your property and is registered in your name, then after that you may sell it. Yes.
