Are we entitled to withdraw the same value as the deposited amount in Yemeni Riyals, given that the exchange rate has changed? And are our funds considered shares in the company, and how is the value of the shares calculated upon exit?

The transaction mentioned is a Mudarabah (profit-sharing partnership), and it can be a combination of Shirka (partnership) and Mudarabah if the Mudarib (entrepreneur) has capital that he invests along with the Mudarabah capital. The Mudarabah contract is among the permissible contracts that can be revoked by the will of either party. Revocation occurs by word or deed, such as the رب المال (financier) reclaiming the capital. If the Mudarabah is revoked and the capital has materialized into profit, the profit is distributed according to the agreed-upon condition. If it is revoked and the capital has not yet materialized, it can be appraised by experts or by agreeing to sell or divide the assets.

The difference in currencies necessitates considering the base currency for the capital (Yemeni currency in this case) to determine profit or loss, even if both parties agree on another currency. The appraisal should be at the rate of the day of distribution, not the day of deposit, to ensure fairness between the two parties.

Regarding the second question, each participant has a share of the stock proportionate to their capital contribution at entry, and according to this share, they are entitled to a percentage of the profit or bear a portion of the loss. If one of the shareholders wishes to withdraw, they are entitled to the value of their share of the stock at the time of withdrawal (on the day of distribution).
