What is the ruling on an online investment company that allows the purchase of shares with a minimum of two shares at a price of 25 Euros per share, and pays weekly profits of 40% of the invested capital for a period of 4 months, in addition to the return of the original amount, provided that certain advertisements are clicked on weekly for 5 minutes, and is it permissible to profit from inviting other people to invest in this company at rates ranging between 2% and 10%?

Any company that guarantees capital and claims to give fixed percentages of profit from it is a usurious and forbidden company, because the profit of a partner in legitimate companies is a percentage of the company's total profits. If the profit is gained by inviting friends to register with usurious companies, then this is forbidden due to its involvement in cooperation in sin and aggression, and Allah Almighty said: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression."
