What is the ruling on the money received by partner Zayd during the period in which he was not dedicating his full time to working for the company, and what is the ruling on the company, given that his partner Omar believes he was wronged due to the profit-sharing ratio not being adjusted after their working circumstances changed?

This company is called "Shirkat al-Abdan" (partnership of bodies/labor), and there is a difference of opinion among scholars regarding its ruling. The preponderant view is that it is permissible. It involves two or more individuals partnering in what they acquire through their labor, such as in craftsmanship or other occupations, like hunters or porters. The profit in this partnership is distributed according to the agreement. If one partner permits the other to undertake a special work while adjusting the profit ratio from the common work, there is no objection. The profit from the special work belongs solely to the partner who performed it. The partner must give their partner what exceeds the agreed-upon percentage after being granted permission for the special work. If the other partner waives what has passed and they start a new agreement, that is good.
