Is working in bank Haram in Islam ? I mean we do n'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 do n'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 ?
