Is my marriage to a woman whose father works for an insurance company, and my eating and drinking at my in-laws' house, unlawful?

There is no objection to working in the field of insurance if it is permissible, like cooperative insurance, and it is forbidden if it is commercial. If the job of the wife's father is permissible, then his salary and gifts are permissible. However, if it is forbidden and he has no other permissible money, then it is not permissible to take from his money. If his money is mixed between forbidden and permissible, it is permissible to eat at his place, but disliked if the forbidden predominates, and it is forbidden to consume anything known to have been purchased with forbidden money. There is no harm in marrying his daughter, even if his job is forbidden, especially if she possesses good character and religiosity.
