Does the ruling of prohibition on a forbidden loan in forex trading fall upon the broker or the client? Is the loan considered fictitious, thereby permitting the trade? And what is the decisive legal ruling amidst the differing fatwas of Islamic bodies regarding these transactions?

We have previously explained that forex transactions containing শরিয়া (Sharia) non-compliances are forbidden for both parties. Among these non-compliances is the margin system (margin trading), because it involves an interest-based loan from the broker to the client, where the broker benefits from this loan through interest or commissions, which is a forbidden "loan that brings benefit." It also involves the forbidden "lend me and I lend you" arrangement, where the broker stipulates depositing a sum to lend to the client. The argument that the loan is imaginary does not change anything, for its being a deception or an imaginary contract without actual possession makes it forbidden. As for the fatwas that permit these transactions, the website is not aware of them and is not concerned with tracking and responding to them.
