What is the ruling on a wife continuing in a marriage to a husband who insists on an interest-based loan, and is she entitled to seek divorce because of it?

It is permissible for a wife to take from her husband's interest-based money if there is no permissible money available for spending, and the sin of that falls upon him due to necessity. However, if permissible money is available that suffices her, then it is not permissible for her to take from unlawful money. In this situation, the wife has the right to remain and spend from her own money, considering it as a debt owed by her husband, or to seek a divorce due to harm. This is because spending from unlawful money or remaining without maintenance is a harm that permits seeking divorce and removes the prohibition of seeking divorce, which is restricted to cases without necessity.
