What is the ruling on working with eToro.com using the Contracts for Difference (CFD) system? And what is the Sharia ruling on Contracts for Difference (CFD)?

Contracts for differences—whether they are options contracts, futures contracts, or similar instruments traded on the stock exchange—are impermissible to deal in due to the presence of gharar (excessive uncertainty/risk) and maysir (gambling). The resolution of the Islamic Fiqh Academy in Jeddah, No. (63), explicitly states that options contracts are not permissible in Sharia because the underlying asset is neither a tangible property (mal), nor a usufruct (manfa'ah), nor a financial right that can be compensated for. The same applies to futures contracts and contracts on indices. However, working on the aforementioned website in transactions other than these contracts and similar ones is, in principle, permissible.
