What is the ruling on profits earned from shares in car insurance companies?

All current forms of commercial insurance are haram (forbidden) because they involve riba (usury/interest) and gharar (excessive uncertainty), and this includes car insurance. The company may not need to repair anything for some policyholders and yet collect money from them every year. Conversely, it may collect a small amount of money from some and incur significant losses on their behalf. This type of insurance may also lead some policyholders to drive recklessly, causing accidents, fatalities, and damages, simply because they know the company will bear the consequences. Therefore, participating in commercial insurance companies and profiting from them is haram, and these profits must be disposed of by spending them on charitable causes.
