All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
Commercial insurance is forbidden as already clarified in Fatwa 81425 but whoever is obliged to do it is not sinful and the sin falls on the one who obliged him to do it or whoever deals with it deliberately.
However, this does not mean that you can work as an agent and the like in a commercial insurance company. That is because it (the commercial insurance) is permissible for the person who is forced to do it, while you are not forced to do this job.
Allaah Knows best.
