The ruling on selling a purchased item before taking possession of it

Your Eminence! Recently, the practice of buying soap on installment has become widespread, where the soap does not move from its place for the sake of the price, and the buyer goes with the invoice to another shop to sell the soap while it is still in its original location.And it is a condition on the one from whom he bought: What is your opinion on taking the soap from the previous shop?
Our opinion is that this is not permissible based on the apparent meaning of the Sunnah; because the Prophet (peace and blessings be upon him) forbade selling goods at the place where they are bought, until the merchants take them to their dwellings.So we say: These cartons that were bought must not be sold, not even one, until they are moved to the shop or to your house.
