What is the ruling on marrying a girl who works for a car insurance company, what is the ruling on working in mixed insurance companies, and what should I do?

Commercial insurance, including life insurance, is forbidden due to its involvement with usury (riba), ambiguity (gharar), gambling (maysir), and the unlawful taking of property. Therefore, it is not permissible to work in insurance companies, as this constitutes cooperation in sin and aggression. Allah has forbidden this, saying: (And cooperate in righteousness and piety, but do not cooperate in sin and aggression) (Al-Ma'idah: 2). As for the wages earned from this work before knowing its prohibition, there is no harm in benefiting from them, based on the Almighty's saying: (So whoever receives an admonition from his Lord and desists, he may have what has already passed, and his affair is left to Allah) (Al-Baqarah: 275).

Therefore, the girl must be advised to leave this forbidden work. If she complies, then there is no objection to marrying her.
