What is the ruling on medical insurance, what is the ruling on cooperative insurance, and what is the ruling on treatment at the company's expense?

Question:
May Allah reward you, Your Eminence, father. The questioner asks: What is the ruling on medical insurance? What is the ruling on cooperative insurance? And what is the ruling on treatment at the company's expense?

Answer:
All commercial insurance, in all its forms, whether medical or otherwise, is commercial, not cooperative as they call it. They call it cooperative, and that is a lie. It is commercial, not cooperative. Cooperative means donation: if a group donates and sets up a fund from which they treat the sick for free.
This is what cooperation is. But if they collect money and say it will be returned to us with profit and investment, that is commercial, not cooperative, and it is forbidden because it is consuming wealth unjustly.
You pay a small amount, and perhaps you are treated for one hundred thousand or more. Some operations are at the expense of the people, at the expense of the partners. What makes it permissible for you to take all the people's wealth unjustly? Yes. It is obligatory for the Muslim to treat himself at his own expense.
From his own money, and praise be to Allah, and he should have good opinion of Allah the Exalted. And if someone donates to his treatment, there is nothing wrong with that. Yes. I ask Allah for you, Your Eminence, father. This is not a donation; this is commercial. Yes.
