Is it permissible to deduct 500 Saudi Riyals from the driver's salary as part of the cost of repairing the car after a traffic accident for which he was at fault, given that there was no prior agreement between you and he is not content with the deduction?

The driver guarantees any damage to the car if the accident was due to his transgression or negligence, such as driving at excessive speed, being distracted by the phone, or neglecting car defects. However, if the accident occurred without his transgression or negligence, he is not liable, because the basic principle is that the hand of a private employee is that of a trustee; he does not guarantee what is damaged under his hand except through transgression or negligence. Forgiving the driver, especially if he is poor, and covering the cost of repair is considered an act of charity, and it is hoped that it will bring blessings and ward off calamities, in accordance with the Almighty's saying: "And whatever good you put forth for yourselves - you will find it with Allah. It is better and greater in reward," and the hadith about the merchant who overlooked the debts of those in hardship, for which Allah rewarded him.
