The seller saying to the buyer: “I will bear the loss if I lose.” Is this contract and this condition valid?

Question:
He says: Honorable Shaykh, may Allah grant you success. If the seller says, “If I lose, O buyer, then I will bear the loss,” and it is the seller who set the condition, not the buyer, is this contract and this condition valid?

Answer:
No, this is not valid. It is a case of gharar (excessive uncertainty in a contract) and ignorance. “If I lose, I will bear it” means he guarantees me the profit. Who knows the profit? This is an invalid condition. And they intend by this to promote the goods. Yes.
