What is the ruling on accepting financial sums offered to a government employee in exchange for performing government services, given that these sums were neither requested nor stipulated, and that the nature of his work requires travel, providing tools, and performing additional work without compensation?

It is not permissible for an employee to accept gifts or money from those he deals with, because if he were not an employee, they would not be given to him. This is considered bribery, as Umar ibn Abd al-Aziz said. The Prophet, peace and blessings be upon him, urged against an employee accepting what is gifted to him due to his position, for an employee, if he sits in his home, nothing is gifted to him. This prohibition is emphasized for those who deal with the public, because accepting these gifts may lead to favoritism towards them and a dereliction of duty towards others. Even if he knows within himself that he will not be swayed by them, he is not entitled to take them because it is money without an equivalent exchange, and its cause is his presence in this position, which is consuming people's wealth unjustly. Uncompensated overtime hours do not justify accepting these gifts, as overtime hours are a right of the employee upon the employer, while the right of those dealing with him is to have their work performed without charge.
