Does Islam permit euthanasia?

> **Definition:** Euthanasia, also known as assisted suicide, physician-assisted suicide (dying) , doctor-assisted dying (suicide) , and more loosely termed mercy killing, basically means to take a deliberate action with the express intention of ending a life to relieve intractable (persistent, unstoppable) suffering. Some interpret euthanasia as the practice of ending a life in a painless manner. If a patient is suffering great pain from a disease, and there is no hope left for him/her with today's technology, can he/she have euthanasia? I know that Islam prohibits suicide in general. What about his special kind of suicide? Is it permissible? Is there any example application in Sunnah?
