Futures are a tool used to lock in future prices for X product/item. That is fine in islam, in which we (Muslims) call it ‘Salam’. BUT, for it to be permissible you have to give the money up front for the product to later be delivered. This is not how futures work, especially as it’s often not even settled with X product, but just trading prices, and therefore no permissible.
This fiqh course I delivered last year will help you navigate your trading needs, as we cover what types of transactions are permissible, what is Ribaa and more importantly, how Salam works.
