The ruling on marrying someone who works in riba-based banks

Question: A young man proposed to my daughter, who is 27 years old, and we reached an agreement on all points, except that the young man works in one of the riba-based banks. When we asked him to leave the bank, he said: If he finds another job, he has no objection, provided that it is close to his current salary at the bank. He also has two families to support, and his work is in the (currency exchange) department of the bank. Please issue a ruling: Is there a sin on me in marrying this person?

Answer: If the suitor’s situation is as described, the advice is not to marry her off as long as he is in the aforementioned job. May Allah guide everyone to what pleases Him.
