If I buy a commodity from you under a defective contract and it is destroyed without negligence or fault, am I liable to compensate for it?

Question : If I buy a commodity from you, it enters my possession with the liability of guarantee, is that not so? Why? Because I did not take it from you except with the guarantee of the price. So if the sale is defective and the commodity is destroyed in my hand without negligence or fault, it is well known that a defective contract must be annulled. So am I liable to guarantee this commodity that was in my hand and was destroyed without negligence or fault, or not?

Answer : The answer is that I guarantee it, because I took it from its owner on the basis that it was guaranteed, is that not so? By what? By the price. So I have now taken it on the basis that I have lost in reality, as if I were the guarantor of it, since I paid its price.
