A. The sale of the silver to A is void, since it was made in error. Similarly, the division of the silver among the partners is void, even though made by lot, since that too was made in error. However, B is not required to compensate A for the money he spent in pacifying the merchants, since B did not know, at the time of the sale, that his silver contained base metal. Moreover, even if B knew the contents of his silver, he would still be absolved from paying A the money he had given to the merchants, since he was only an indirect cause of A's loss, though he would be liable to punishment by the Heavenly Court.

A. Robbing a Gentile is prohibited, but one is permitted to annul a Gentile's debt (if he can do so by using plausible excuses and without causing the name of the Lord to be profaned). But, if A will be forced to pay the debt to the Gentile, he will not have to pay anything to B.
