Is it permissible to marry a religious woman who works in a usurious bank and has no other source of income?

If the girl is willing to leave her work in the usurious bank and repent, there is no impediment to marrying her, while seeking out lawful work for her. Her unawareness of the danger of usury might have been the reason for her work. However, if she is not willing to repent and abandon unlawful work, then you must seek out a woman of faith. And whoever gives up something for the sake of Allah, He will compensate him with something better.
