What is the ruling on reclaiming the dowry paid for an engagement to a girl if the engagement is dissolved, knowing that the dowry was liquid money and gold was purchased with it for a value greater than the dowry?

If the money was paid as a dowry and the engagement was annulled before the marriage contract, you have the right to reclaim it.

If you instructed them to buy gold (the bridal jewelry) with your money, you have the right to claim the gold, not the paper currency. The value of the bridal jewelry will be divided between you and the girl's family according to each of your contributions to its price.

However, if they bought the gold without your permission, you have the right to claim the amount you paid, and you are not obligated to take the gold.
