Is it permissible for a partner to monopolize the entire profit on the pretext of his follow-up of the work, despite the prior agreement on equal partnership and his promise of a percentage for management?

The profit in a partnership is divided according to the capital contribution of each partner, unless otherwise agreed upon. If one of the partners undertakes work that is not required of him as a partner, he is entitled to request an increase in his share of the profit or a lump sum payment for his work, provided there is a prior agreement. If he does so without an agreement, he is not entitled to anything unless his partner agrees. The partner's statement that the questioner has no right except to his capital is void, and he must hand over his share of the profit if it exists.
