Working in a shop that sells religious items of other religions

Q: I am a Muslim working with a non-Muslim in an exhibition show. He is selling antiques which relate to all religions e.g. Buddha statues, Christian crosses, items decorated with the names of Allah Ta'ala, etc.  My job is loading, unloading and security, and I keep these things in a showcase.

Joining the police force

Q: If a Muslim joins the Police Force or even Community Police Forums and other crime fighting groups within the law with the intention to eliminate fitnah, will there be any reward for it if he is killed while doing so? Will he become shahid?

Working for a company that offers business development services

Q: I work in an organisation named JKEDI which is an entrepreneurship development institute and its mission is to make youth self employed so that they attain financial independence as its very difficult to get a government job here and the unemployment rate is alarming. JKEDI trains entrepreneurs, offers business development services and provides them finance for starting their business by linking them to banks where they are charged interest and give loans directly also. I am working there as a trainer. I want to know whether my job is halaal or haraam. And in  case its haram, can I continue working here till I get another job or I should quit?

Doing an accounting job

Q: Is it permissible in Islam to have an accounting job? Or a financial analyst? Every company nowadays deals with interest. So avoiding it
completely will be very difficult. Please advice in which situations it will be permissible and impermissible? 

Working for a company that is involved in making arms

Q: I am trying to find out for a friend the permissibility of working for a company that is mainly involved with making/creating arms and selling them to companies globally including countries that use them to kill Muslims. The companies main areas of business are Defence (80%) and remainder Space/Travel. He would be working in the IT division and would have no direct involvement with the defence areas of business. He has asked a few well known scholars who said it would be deemed permissible but wasn't able to get any elaboration/clarification as to how it was exactly permissible. The company is also involved in talks with creating an office in Tel Aviv.
