What are the alternatives to compound interest for a Muslim?
I am not sure if these are available today in your country:  but supposedly, back when Catholic countries similarly forbade usury, sinecures were invented to circumvent religious restrictions on finance. Meaning literally 'without care', sinecures were formally prestigious salary-paying jobs with few responsibilities. They were bought by the wealthy from the Church or State. The salaries for sinecures, accumulated over time, exceeded the initial purchase price. As such, some moderns consider sinecures usury in all but name.
