What is the ruling on buying and selling goods that have not been received or inspected, but rather left in the warehouses of the original seller and transferred by a bill of sale and receipt?

It is not permissible for the buyer to sell the goods while they are still in the possession of the seller until he takes possession of them and transfers them to his ownership, due to the prophetic traditions that prohibit selling what one does not own or profiting from what has not been guaranteed. Examples include the Prophet's (peace be upon him) saying: "(It is not lawful to combine a loan and a sale, nor two conditions in one sale, nor profit from what has not been guaranteed, nor sell what you do not possess)," and his saying to Hakim ibn Hizam: "Do not sell what you do not possess," and his prohibition of selling goods where they are bought until merchants take possession of them and transport them to their homes. This also applies to whoever buys them from the first buyer.
