Is it permissible to take 50 Riyals as an incentive from a car maintenance center after claiming responsibility for the maintenance of company cars in order to receive better service?

The Prophet Muhammad, peace and blessings be upon him, likened a person who pretends to have what they do not possess to someone wearing two garments of falsehood, because it involves lying to oneself and to others. It is obligatory to repent to Allah and return the money taken fraudulently to its rightful owners, as this constitutes consuming people's wealth unlawfully, and lying and cheating are falsehoods.
