Is it a forward sale (salam) for a merchant to receive half the price on the condition that he delivers the goods the next day?

The questioner:
In the name of Allah. Your Eminence, father, the questioner says: Sometimes a buyer comes to a seller and says, "I want such-and-such a product," but that product is not in the shop. So the seller takes the price or part of it, on the condition that he will bring the product the next day.

The Shaykh:
This is not permissible unless the product is brought. They negotiate when the product is brought. They negotiate over it. But before the product is brought, this is not permissible, because he is selling what he does not own.

The questioner:
Yes. He says: May Allah reward you. In the continuation of his question, some people issue a ruling that this is a forward sale (salam), knowing that.

The Shaykh:
No, it is not a forward sale (salam). A forward sale (salam) is deferred, and this is not deferred. A forward sale (salam) is fixed by description, and this is not fixed by description. In a forward sale (salam), the full value is received at the time of the contract, whereas in this case, the value is not paid until the product is brought. Yes.
