What is the ruling on dealing with the Shifa card and health insurance in pharmacies, knowing that it allows for the purchase of medicine without payment or with a payment of 20% depending on the subscription?

The ruling on dealing with these cards depends on the type of insurance: if it is cooperative, there is no objection, but if it is commercial, it is prohibited. This does not affect your studies, and if you graduate and become a pharmacist and sell medicine to the holders of these cards, there is no impediment to receiving your due from them through this system.
