Is it permissible to benefit from the medical insurance service provided by the German insurance company (Allianz) as an incentive from the company, given that the company pays the full annual premium without any deduction from the salary, and what is the ruling for one who seeks treatment at his own expense and then demands reimbursement from the insurance company?

Insurance is of two types: Prohibited (Commercial) Insurance: It is not permissible to benefit from it beyond the amount paid into it, because it is based on Gharar (excessive uncertainty), gambling, and consuming people's wealth unlawfully. Permissible (Cooperative) Insurance: This is based on volunteering and cooperation in righteousness, and it is permissible to benefit from it according to the terms of the agreement, even if the benefit exceeds the amount paid.

This detailed explanation applies to claims for reimbursement of treatment costs from insurance companies.
