1) When working for trading firms and any firms in general, am I correct in thinking that unless I know for a fact the firm engages in any illegal activities, I can assume they operate legally in everyway, and therefore no need to investigate as i can trust them? 2) Also syed, on the topic of forex trading firms I have another query: forex trading firms are companies which allow people access to their funding so that traders can trade using their money. Now i personally trade only halal currencies and stocks because I am a muslim. However non-muslims also trade using these forex companies and as a result trade stocks which are haram like dax30 etc. now my question is, when I get the funding from the company, theres a possibility it is from that portion of the companies income where they received profits from haram stocks. However this is only a possibility as there could also be a realistic possibility I receive funding from their portion of profits which are halal . Therefore my question is, if I am no certain at all that my portion of funding received by the company is from their haram profits (as it may well be from their halal portion) am i correct im thinking it is permissible for me to use it?
