Is it permissible, obligatory, or forbidden to seek divorce in the event that the husband insists on taking a loan from the bank to buy a house, despite the wife knowing it is an interest-based loan and her desire to avoid usury?

The described transaction involves an interest-based loan (riba), which is impermissible, except in a case of dire necessity, which does not apply here. The fact that the company pays the interest does not make it permissible to sign an interest-based contract. The husband should seek permissible financing methods, such as Islamic banks. The wife has done well by advising him. Her demand for divorce is not obligatory, and she should not force him to choose between her and the loan. If the husband takes the loan, the wife is not prohibited from benefiting from it, nor is he required to give away some of it in charity. However, if he does give some in charity, it is better for repentance and expiation of sins. Regarding in vitro fertilization, its legal ruling and regulations have been clarified in previous fatwas.
