Is forex trading permissible or forbidden, especially after someone gave me 10,000 out of a 44,000 profit for an amount of 10,000?

Investing in the global currency market (Forex) is permissible if Islamic legal controls are observed, such as the actual or constructive exchange (qabḍ) in transactions where it is required, and avoiding religiously prohibited matters such as: leveraged financing (margin trading), overnight fees (rollover fees), selling what one does not own, and trading in what is not permissible, like "binary options." If the investor adheres to the Islamic legal controls and avoids the prohibitions, then there is no objection; otherwise, it is not permissible.
