What is the ruling on investing in an American company that operates in the trade and manufacture of electronic devices, where the investor pays a certain amount and the company commits to paying specified profits periodically throughout the year, with capital insurance guaranteeing its recovery in case of the company's bankruptcy, knowing that the profits may be unspecified if the amount paid is less than $10,000?

This transaction involves several Sharia-prohibited aspects: placing money in usurious banks, the company insuring shareholders' money with a usurious insurance company, guaranteeing the capital and a fixed profit which invalidates the contract of Mudarabah, and the reality of this transaction being a loan with an increment. Furthermore, the determination of the profit share in Mudarabah must be known. Based on this, it is not permissible to invest money in this company due to these Sharia-prohibited aspects.
