What is the legitimate Islamic alternative to investing in global stock markets, to encourage Muslims to abandon these forbidden dealings?

Global stock markets are often not free from the aforementioned Sharia (definition) prohibitions, and dealing with them requires vigilance and firmness to avoid falling into the forbidden. It is important to beware of the forbidden, especially usury (riba), as it is among the gravest sins. The Islamic alternative is to invest money in permissible matters such as buying and selling (bay' and shirkah), or in the financial market with Sharia compliance. There are many books and research papers that explain the Islamic alternatives to forbidden transactions, and Muslims must apply Islamic theories and adhere to Sharia regulations in their financial dealings.
