What is the ruling on AlAhli's Tawarruq, given that its format involves taking a commodity and authorizing Al-Essa Company, and no other, to sell it, with the right to receive and dispose of the merchandise?

The bank's condition that the buyer must not sell his commodity except through a specific person is a void condition because it contradicts the nature of the sales contract and freedom of disposal, and it imposes restrictions on the buyer regarding his property. The sale is valid, even though the condition is void. However, if the bank itself or its appointed representative sells the commodity, this makes the transaction unlawful, similar to organized tawarruq.
