Is it permissible for a wholesaler to sell his goods to a retailer for a deferred price until the retailer sells the goods, provided that the sale is binding, the goods are under the buyer's guarantee, and the price is known?

It is not permissible to sell with a deferred price to an unknown term, as there is a consensus among jurists on this matter, and the sale is فاسد (invalid) and must be rescinded. If the wholesaler wishes to sell his goods to the retailer again, the term must be known, or the wholesaler must authorize the retailer to sell the goods for a known fee.
