What should I do to close my account in a usurious bank, given that I have incurred a debt due to deduction fees, and am I sinful for that?

If the questioner withdrew his money from the usurious bank out of repentance to Allah, then he has done well. However, if the account is a current account for safeguarding money, and the bank deducts a monthly sum as fees or charges, then these charges are a debt that must be paid. It is not permissible to open such an account in usurious banks except out of necessity, even if no usurious interest accrues from it. As for how to close the account, specialists should be consulted regarding that.
