What is the ruling on working for a company that designs computer software used in financial transactions and for predicting stock prices, given that the program includes other functions that may involve the شبهة (doubt/suspicion) of dealing with loans, and that it is used by individuals, government entities, and banks? And does it affect the ruling if banks might use it in unlawful applications?

Working for the aforementioned company, in permissible matters, provided that one does not directly engage in or directly assist in anything forbidden, is not objectionable. This includes programs that study the market and stocks and provide analyses and forecasts, provided that the information does not pertain to stocks or usurious loans whose trading is forbidden. As for what is permissible to trade, there is no objection to studying it and providing recommendations and forecasts concerning it.
