Is it permissible to deduct an amount from the monthly profit of a partner if he is absent from work, knowing that the partnership is based on an equal division of profits, and that the partner is often absent, and the other party is responsible for managing the premises and its operations?

The default is to refer to the conditions agreed upon in the contract; otherwise, to custom. If neither applies, then: if the absence is excusable, he should not be penalized, and he must appoint someone to work in his place at his own expense, otherwise, the partner has the right to terminate the contract. If the absence is without excuse, scholars have differed: some believe that the partner is entitled to his full share of the profit even if he did not work, while others believe that he is not entitled to his full share due to his breach of the agreement. The previous contract should be terminated and a new agreement made to distribute profits in the event of one partner's absence.
