What is the ruling on an unmarried young man working as a taxi driver for an app, where women often ride with him alone, and he feels anxious fearing falling into temptation or committing something forbidden?

If a Muslim fears temptation for himself or falling into something unlawful, it is not permissible for him to be alone with women in a car, even if it leads to him leaving his job. However, if he is secure from temptation, then he is not obliged to leave this job, but he must be wary of temptations and prioritize the safety of his religion.
