What is the ruling on money earned from a café that combines halal and haram, and is it permissible to marry a girl who is supported by this money?

There is no objection to marrying a girl characterized by religiosity and good character. Her father's involvement in selling what is lawful and unlawful does not affect her, as the sin is solely upon the father. It is permissible to eat from the food of a man who earns his money from both lawful and unlawful means because it is mixed wealth.
