What is the ruling on trading in Forex through a company that allows instant withdrawal of funds, while manually avoiding the use of leverage and avoiding overnight holding (al-bayt)?

Using financial leverage (margin trading) is prohibited because it is a loan, and two prohibited matters result from it: overnight fees, which are considered usury (riba) because they are a conditional increase on the loan, and combining a loan with brokerage (the institution's commission), due to the Prophet's (peace be upon him) prohibition of "a loan and a sale." The Islamic Fiqh Academy has issued a resolution prohibiting margin trading (forex) for the same reasons, in addition to the non-fulfillment of the Shariah-compliant possession (qabd) in the sale of currencies and precious metals. However, if trading is conducted using only personal funds without financial leverage, and possession (qabd) is fulfilled at the contract session when purchasing currencies, then the transaction is permissible.
