Q. I would like to know if I can get my toilet tank fixed from my bank interest money and could I also pay the plumber from the same interest money.
A. It will not be allowed for you to fix your toilet tank or pay the plumber from your interest money (from the bank). This act will show that you are using and benefiting directly from your interest money which is not permissible.
And Allah knows best.
