All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
It is known that the field of purchases and sales of currency and exchange is narrower than other forms of sales and transactions and more likely to involve prohibition. Nevertheless, there is no harm in it if it is regulated by the Sharee’ah limits. It is in principle permissible as previously clarified in Fatwa 129786. Violation of some of the regulatory laws in this regard does not prohibit benefiting from the profits a man gains thereof although abidance by the laws, even those of foreign countries, is obligatory in some cases in order to save the person from danger and accountability. Also, many of these laws were laid in order to achieve public interest, so it is necessary to abide by them.
Allaah Knows best.
