What is the ruling on taking permission to deliver a product not yet manufactured as a guarantee for Murabaha?

If the bank requires the authorization as a guarantee of the client's seriousness in proceeding with the Murabaha, then there is no objection. And if it intends to hold him liable for the value of the actual damage should the client fail to proceed with the Murabaha, or fail to make the installments after its completion, and the delivery of the commodity with this authorization is certain, then this is permissible. An analogous case is pawning the sold item for its price with its seller before taking possession of it, because its possession is due. Sheikh Ibn Taymiyyah chose the permissibility of pawning fungible goods (measured and weighed items) and the like before taking possession of them.
