What is the ruling on participating in buying a certain stock or currency and profiting from it, if there is an agreement to buy it at a specific time with the aim of raising its price, and then selling it after its rise?

The aforementioned transaction is not permissible in Islamic law because it involves deception, market manipulation, and harming others. It also contains the meaning of "najsh" (inflating prices), which is prohibited, whether by raising or lowering the price. These practices are considered consuming people's wealth unlawfully, as stipulated by the regulations of the Capital Market Authority, which prohibits fictitious or misleading trading that aims to create a false or misleading impression or to influence the price of a security. Participation in these illusory acts is not permissible.
