What is fundamentally unique about Islam?

What, if anything, is _fundamentally_ unique about Islam? Obviously there are different stories, texts, and traditions associated with Islam than with other religions. But if we cut away all the fluff from all the world religions... Is there anything that stands out as unique about the core of Islam? To clarify what I'm asking: * Many religions have prophets that claim to speak on behalf of god(s). * Many religions have scriptures, often claimed to be inspired by their god(s). * Many religions report miracles, or other supernatural phenomena. * Many religions claim to be the only "true" religion. * Many religions claim to offer forgiveness of sin. * Many religions claim to be historically based and accurate. * Many religions claim to improve society. If Islam just has a "better version" of all of these points, it sounds like Islam is fundamentally the same as most/all other religions, it's just "more completely evolved," so to speak. So what I'm asking for is any characteristics of Islam that are **fundamentally unique and important**, and not just improvements on existing ideas.
