Is margin trading in the stock market or through the Forex system prohibited, and can it be made permissible?

The follower must adhere to the most knowledgeable, the most scrupulous, and the most pious, not choose based on personal desire. When there is a difference in fatwa, one refers to the hadith of Wabisa: "Righteousness is that to which the soul feels tranquility... and sin is that which wavers in the heart...", and the hadith: "The lawful is clear, and the unlawful is clear, and between them are doubtful matters...". Dealing with the margin system (financial leverage) is usury because it involves a loan with interest or commissions, and because of the risks involved. As for brokerage, it is permissible if it is in lawful matters, and not in forbidden stocks or usurious transactions. In currency trading, immediate possession (qabd) is a condition, and the agent is like the principal. Furthermore, the currency of a single country is a usurious category, and it is not permissible to exchange it unequally according to the hadith: "Do not sell gold for gold unless it is like for like...". These regulations are often not adhered to by global stock exchanges. However, if they are met, then there is no harm in engaging in trade or working as a broker in them.
