What is the ruling concerning the salary of a female pharmacist who works two or three days a week in a health office due to a large number of staff and a low workload, and is this salary considered unlawful? If it is unlawful, is it permissible to give half of it to the poor to purify the remainder? And what is the ruling concerning the money saved from this salary?

It is obligatory to return the portion of the salary that corresponds to the absence from work to the employer. If the exact amount is unknown, it should be estimated based on what is most likely to clear one's conscience.

One's obligation is not fulfilled by donating the amount as charity, unless it is impossible to return it to the employer. Any remaining salary after that is rightfully due to the employee.
