Is working in bank Haram in Islam? I mean we don't take money, All profit goes to the owner and then he gives us the salary.
A person I know has an idea for a mobile application but no skillset or money to build the application. I don't want to steal his idea so is there a widely accepted standard for example where I would take 90% of the profits for doing all the work and he would get 10% for just the idea?
