Does divorce occur if the husband says to his wife: "If you sell anything else to my father, then you are divorced," and the wife displays something for sale but does not sell it?

If a husband conditions his wife's divorce on his father selling something, and the sale does not occur, then the divorce does not take place. The husband must be wary of frequently swearing by divorce, and he must guard against anger. You both should treat each other kindly to avoid provoking him.
