Is it permissible to remove one of the partners from the company due to the failure to achieve the previously agreed-upon goals, especially given that he has not been able to generate any sales within three months, in addition to receiving his monthly share?

A partnership is a non-binding contract that any partner may terminate at will. Among the conditions for a valid partnership is that the capital must be tangible, not a debt, and present at the time of the contract. If the partnership becomes invalid, each partner receives their invested capital along with their share of the profit or loss, according to their respective shares. Each partner also pays the other for their work if they contributed labor to the partnership.
