Islamic Bank accounts
Q: There are "halaal" bank accounts at conventional banks, who engage in ribaa, and I was wondering if it is allowed to create an account at a conventional bank, which is closer and more convenient when there is an Islamic bank, but further away and with only I think one or two branches where I live. Because even though I would not be getting interest, they will still be benefiting from the money I gave them, via investing it in a permissible way, which helps their business, which is a ribaa bank. Please let me know if it is sinful.
