If there is no Islamic bank or a bank that doesn’t give interest, in this case, it is permissible to keep such an account but You need to get rid of interest in means of charity.

There is something bothering me regarding the savings account in an undoubtedly pure Riba-based bank. I save my money because keeping it with me exposes the money to unnecessary spending & it is quite unsafe. I have even recently written to the manager to remove any interest attached to my account. Can I continue saving in this bank as a necessity?
