Since the said insurance is optional and you want it for fear of something expected, then it is not permissible to subscribe to it if it is the commercial type, which is based on risk and chance as stated in Fatwa 81425.
It does not become permissible for you to purchase this insurance based on what you have mentioned. So, you should place your trust in Allaah and depend on Him to keep you from harm and protect you from what you fear.
You should know that what Allaah has is only obtained by obeying Him and not by disobeying Him. Allaah says (what means): {And whoever fears Allaah – He will make for him a way out, and will provide for him from where he does not expect. And whoever relies upon Allaah – then He is sufficient for him. Indeed, Allaah will accomplish His purpose. Allaah has already set for everything a [decreed] extent.} [Quran 65:2-3]
Allaah Knows best.
