Is the employee entitled to the delayed annual bonus, which was approved but not disbursed due to financial circumstances, considering it a debt owed by the company, or is he not entitled to it because he resigned from work before its disbursement, and given that the prevailing custom in the company and similar companies dictates that the bonus is only disbursed to an employee who remains with the company as an incentive to stay?

The bonus is either stipulated in the contract or it is a gift. If it is stipulated and its determination is subject to regulated criteria, then the company is obligated to fulfill it, due to the general evidence indicating the obligation to fulfill contracts, such as the Almighty's saying: "O you who have believed, fulfill [all] contracts." However, if the criteria for its determination are not regulated, then it is not considered part of the salary due to its uncertainty, and the employee is entitled to a fair wage. What has been mentioned applies to all employees. If it is not stipulated, it is a gift, and a gift is not owned except by possession, according to the preponderant opinion. Its ownership is subject to the company, and it has the right to give it to whoever continues to work with it.
