Is it permissible to hand over an amount to a partner with an estimated profit margin before the end of the specified partnership period, based on his request?

The answer depends on the type of partnership:

1. If it is a partnership between two partners contributing capital: The profit is divided according to each partner's capital contribution, and the loss is borne by the capital. If one partner expends additional effort, it is permissible for him to receive a salary or an additional percentage of the profit for it.

2. If it is a Mudarabah partnership (capital from one party and effort from another): The two parties agree on a common percentage of the profit for the worker, and the loss is borne solely by the capital. It is permissible to agree that the worker performs tasks such as weaving and selling clothes or leather, as these are typical merchant activities.

In both cases, it is impermissible to guarantee the capital to the owner (except in cases of transgression or negligence on the part of the worker), and it is impermissible to give the owner a fixed amount from the profits; because a partnership necessitates sharing in both profit and loss.

It is permissible to agree on a specific duration for the partnership, and upon its expiry, the partnership must be liquidated and the profit and loss for each party determined.
