Forex, which is a kind of currency trading through the internet, involves some factors that may conflict with the sharia.
Shedding more light on this, Dr. Monzer Kahf stated:
Forex is speculation with currencies. It does not have a productive objective nor does it produce any benefit to society or humanity, so from where would you obtain your profit? It comes from someone else’s loss. The account may be with no interest, but that is not sufficient for it to behalal because we are talking here about speculative non-productive transactions or trading that is done without the objective of creating value.
When it comes to the specific conditions of trade, we find that the Prophet (peace and blessings be upon him) made two very important conditions in trading currencies:
1) Payment must be in full in both currencies.
2) Payment must be at the time of the contract.
In Forex you buy on a margin, that is, you buy 100,000 worth of a currency but pay only 5000. It is incorrect to think that the broker lends you 95,000 without interest; the contract itself requires only a small amount to commit that large sum. Moreover, the second condition is not satisfied because most transactions are futures.
This means that even if the payment is made in full and at the time of the contract (i.e., no margin transaction and no futures), the transaction is notharam; but it remains a matter of profiteering from speculative dealings without making any real trade or production.
I would not advise any one to use Forex because its transactions are said to be interest free but are, in fact, in a violation of the rules of currency trading (this violation is calledriba in Sharia , under the nameribaal Fadl) and even when one trades with full payment and with no futures, it is extremely speculative and non-productive.
