How are profits to be divided among four partners, three of whom handle management and exert effort and set monthly salaries for themselves, while the fourth owns 50% of the capital and has no role in the work?

According to the majority of jurists, there is no objection to some partners receiving a fixed wage for their effort, in addition to their share of the profit, which is divided according to their agreement. It is not a condition that the percentage be determined by the capital invested. Al-Khiraqi explicitly stated the permissibility of this, and that the profit is distributed according to what the partners agree upon.
