What is the ruling on currency trading, and which is better, stocks or currencies? How does one trade, participate in buying and selling, and open an account? What is the best bank or broker, knowing that I have vowed to Allah Almighty to spend half of the profit in the cause of Allah?

Directing money towards optimal investment requires adherence to the rulings of Islamic Sharia. Trading stocks and currencies occurs through global stock exchanges, which often fall into Sharia transgressions. Selling currencies must be done with caution due to the mixing of permissible and impermissible elements within it. If a Sharia-compliant investment method is found, then the vow that was made must be fulfilled.
