Our Sheikh Al-Othmani said in the jurisprudence of sales (2: 95): "International sales conducted through bank credit can generally only be categorized as a promise; this is because bank credit is usually opened when there is a binding sales agreement between the parties, and this agreement cannot be considered a completed sale in most cases; because it is often signed at a time when the seller does not possess the required quantity of the sold goods. It is known that selling what one does not own is legally invalid, even if the sold item is owned by the seller, as the sold quantity is not specified. Moreover, the agreement requires the postponement of the delivery of the sold item, which leads to the postponement of both exchanges, and selling a promise for a promise is entirely prohibited by law. Thus, there is no way to correct this process, which is indispensable in international trade, except by considering this agreement as a promise for a sales contract after fulfilling the agreed-upon conditions," and Allah knows best.
