Is it permissible to receive a transportation allowance from a private foreign company contracted with the state, in exchange for commuting with one's private car, instead of using a taxi whose cost the company would cover?

The basic principle regarding a gift received by an employee because of their job is that it is unlawful, based on the Prophet's (peace be upon him) saying: "Gifts of workers are ghulool (treachery/ill-gotten gains)," and his saying concerning someone who was given a gift because of his work: "Would he not have sat in his father's and mother's house to see if he would be given a gift or not?"

The aforementioned agreement, even if not a gift, involves favoritism and influences the supervisor's work, placing it within the realm of suspicions. This is because such agreements can affect the employee's trustworthiness and make him lenient in his duties. What further confirms the prohibition is the supervisor's dislike for people or officials to know about it. The advice for the employee is that the company should pay the taxi fare instead of the supervisor financially benefiting from the agreement, and whoever gives up something for the sake of Allah, Allah will compensate him with something better.
