Leverage is considered a dangerous tool in the trading world, as it allows an investor to open positions that exceed their actual capital, thus multiplying potential profits, but it also doubles losses. This tool can lead to the rapid loss of the entire capital, especially with market fluctuations. From a legal perspective, leverage is considered prohibited because it relies on usurious loans, where the trader borrows from the broker in exchange for interest or an implied condition that falls under usury. Additionally, it opens the door to gambling, making its use contrary to the principles of Islamic law in legitimate trading.
