What is the ruling on the "non-invested" savings plan at Aramco, in which the company provides a bonus proportional to years of service, and the amount is collected in a trust fund that is not invested, and from which the employee is permitted to withdraw and then repay it as a Qard Hasan (benevolent loan)?

The permissible savings are a conditional grant from the company to its employees, and the deduction from the salary is nominal and obligatory. The employee knows that his salary is what he receives after the deduction. The company adds a bonus based on the length of service and pays the total upon retirement or resignation. The company is allowed to lend to employees from this fund, provided that the amounts are repaid in installments. These funds are the property of the company until they are granted to the employee.
