Ruling on selling goods for a profit on their price

Question:
Some merchants buy cars, then offer them for sale on deferred payment with an increase of half the known price, for a period of one year or six months. Is there any doubt of riba in this profit? Because he bought this car intending to sell it for a profit. Is this permissible?

Answer:
We have heard of this, and there are many questioners. It is that some people, or a specific person they mentioned, buy cars at high prices for a known term, and then he deals with them afterwards in his own ways. We do not know of any harm in that if he is of sound mind, not a spendthrift, nor a madman, but a sane person of sound judgment. He has the right to buy on deferred terms at high prices and deal with them afterwards, selling them for cash, or selling them for things he deals in. There is no harm in that.
And a good may be bought at a high price if it is for a term. And the Prophet (peace and blessings be upon him) bought one camel for two camels for the sake of charity.
So the conclusion is: buying varies. A camel may be bought for camels, and a sheep for various types of sheep, and goods may be bought through many types of contracts, and others.
So the conclusion is: if he buys a car that is worth ten thousand, and buys it for twenty thousand, or thirty thousand, on deferred terms, or for multiple terms; there is no harm if he is sane and of sound judgment. There is no harm in that.
