What is the ruling on creating a demo account with virtual money on a brokerage platform for the purpose of learning and simulating the market, knowing that trading is only permissible in sharia-compliant stocks?

It is permissible to trade in pure shares, which are shares of companies engaged in lawful activities that do not deal with Riba (usury or interest), whether through deposits or borrowing. It is prohibited to trade in haram (forbidden) and mixed shares. Mixed shares are shares of companies engaged in lawful activities that do deal with Riba.

Regarding the "Simsar" platform: If the transactions involve cash, gold, or silver, immediate possession (al-Qabd) is required, and deferment is not allowed. If the shares are virtual for simulation and learning purposes, there is no objection. However, caution must be exercised to avoid practicing forbidden transactions such as dealing with margin, contracts for difference (CFDs), options, or futures.
