Am I entitled to reclaim my gold investment at the current selling price, especially given that the price of gold has risen significantly since the initial deposit with which the gold was purchased?

It is understood from the question that the inquirer paid 45,000 Saudi Riyals to a gold shop owner to manage it as a mudarabah (profit-sharing partnership). The capital is the aforementioned amount, and anything in excess is considered profit. To determine the profits, the capital must be liquidated into cash or appraised. Then, the surplus is divided according to the agreement, and the capital of the shop owner must be known. As for the payment of monthly profits, profits do not become apparent until the mudarabah concludes or an inventory is taken. It is permissible for these amounts to be advance payments on account, to be settled later. If the amounts are fixed and unrelated to profits, then the transaction is a loan, and the shop owner is only entitled to a fair wage for his work, while the capital and all its profits belong to the inquirer.
