Is a bank loan with interest that a young man takes out to finance his marriage considered an usurious loan, and is it permissible for a woman to accept marriage from this young man?

It is not permissible to take out an interest-bearing loan for marriage or for any other purpose. If the suitor has taken out a loan with interest, then his situation should be considered: if this was a lapse on his part and he is a person of religious commitment and good character, then there is no objection to marrying him. However, if he insists on his action and does not care, then it is not advisable to marry him, and one should seek guidance through Istikhara and consult with people of sound judgment.
