But you underestimate the fatwa and issue rulings from your own head; the sin of this is much greater.

Why are futures contracts forbidden?
This is a question that has been repeatedly raised.
I addressed this matter in a previous post, but it did not gain the desired spread, so I decided to republish it to reach a larger audience.
First:
In futures contracts, you do not own the asset in a real and actual sense.
You are not buying the currency; rather, you are betting on its future price while not owning the actual currency, which makes it closer to gambling since you are merely betting on the price, and this is based on speculation and pure guesswork.
Second:
The presence of leverage (Leverage)
Leverage amplifies both profits and losses.
But it also makes the deal based on borrowed money,
entering the realm of usury because you are trading with money that does not belong to you and may incur interest on it or be liquidated upon loss.
Third:

High uncertainty and risk.
Sharia prohibits sales that involve ignorance or significant uncertainty.
In futures contracts, you do not know what will happen tomorrow, and the market is very volatile.
Thus, the process turns into a bet on the unknown rather than a real sale.
That is, futures contracts are based on three legal prohibitions:

1. Not owning the asset
2. Presence of leverage or borrowing
3. Uncertainty and gambling

This is why cryptocurrencies are considered forbidden in Sharia.
We ask Allah for success and guidance.
