No, they use a changed version of the Quran and Hadith. And even the stuff where the Quran gets violent, you have to realise that it's also recording history, just like the Bible, therefore those violent parts are generally referencing the time when Muslims were being hunted down and killed by Arabs. What people do is take these parts of the Quran, where Muslims were fighting for their lives, and quote the violent parts without the context. In fact I'm pretty sure they are using an edited version of the Quran. That's what the fucking terrorists do and that's what Muslim bashers do, literally the same fucking thing.
The Quran even talks about Jihad and it's unlike any of this bullshit you read. A military Jihad can only be called by the highest of scholars, and must be avoided at all costs, if it is required, absolutely no innocent people can be harmed, as stated above that's like killing all of mankind. Any terms of peaceful solutions must be sought out and accepted. War has to be avoided at all costs. Even stoning people is not in the Quran, it's from the Hadith that just added shit in later on and these assholes used it to brainwash and radicalise people. The Quran is about preserving life not taking it away. Do they follow that? Nope. They aren't Muslims, they aren't following the Quran and God is not with them. They walk alone.
Hell even the Quran references other religions and calls them, "People of the Book" and says that they must be protected, even Christians and Jews. Where's the violence and hate in that?
Also the Hadiths, why the hell do they all seem contradict the Quran? Doesn't that seem fishy to you? The majority of them were also written almost 200 years later.
The Quran doesn't advocate violence at all, it states, "Killing one person is like killing the whole of mankind". I'm not a Muslim, but I used to be one and abandoned it because I don't believe in God. However, I can show you Muslims who are some of the greatest people I've ever met, I've grown up with Muslims in London for my whole life. We've fought and stood together along with Christians and atheists, protected each other, played together and when a "Muslim" decides to bomb us or stab someone, we band together.
Hell, even when it comes to homosexuality, sure it's called a great "sin", which I don't believe it to be and the part I disagree with most, but the Quran does not say to kill these people! It doesn't even say how they should be punished, AT ALL! That was added in the Hadiths centuries later, with the killing. Most scholars adopt a "don't ask, don't tell policy" and the Quran states that if you repent, then you are forgiven. I know gay Muslims and their family accepts them for who they are.
Yet these fucking clowns think that they can change that? No they can't, that "You Ain't No Muslim Bruv" thing which united most of Britain is exactly the kind of thing I expected. We have grown up with Muslims, we know what Muslims are and they are not attacking or killing us and hate these twats. I'm not a Muslim anymore, but I will still defend their religion and what these people have done with the Quran, how they've warped people into killing for them, that's not Muslim.
These people are not Muslims, despite what you say, call it the "No true Scotsman" crap, but they are not Muslims. They have changed the teachings, brainwashed people with statements that are taken out of context and turn to the extremes through the Hadiths, which all contradict what's taught in the Quran.
Given I'm no Muslim scholar and only go by what I was taught and read, I may be completely wrong for all I know. But, the fact that a huge majority of the Muslim population despise ISIS tells me everything I need to know.
