Dr. Monzer Kahf, a prominent economist and counselor, states that: “If one pays a higher price at the time of purchase for an object (e.g., a car) in order to include a maintenance warranty like what is practiced under the name of extended warranty to five or seven years, this is permissible almost unanimously to the best of my knowledge.

On the other hand, buying an independent maintenance agreement that gives this kind of warranty is not so much agreed upon. It is, in fact, a kind of insurance. Those Muslim scholars who argue that insurance is permissible see this contract as permissible, too. While those who prohibit insurance on the basis of ambiguity with regard to the exchangeable obligations of the two parties consider this contract prohibited, too, on the ground that you don’t know what service the object may need and at what time.”
