What is the ruling on working for the company Al Mutadawil Al Arabi (The Arab Trader), a Saudi company specializing in financial services and training on trading in currency markets such as the stock market and Forex?

Working in financial consulting and training on dealing in international stock exchanges is permissible if it involves permissible matters, and it is not permissible if it involves prohibited transactions; this is based on the Almighty's saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression."
