ISIS / Daesh - The Rules of War in Islam

Those tree cutting bastards!

I'd love to see an actual source on these supposed Quranic teachings.
They all sound like something that was taken far out of context and simplified into a manner which makes them seem different from what they actually mean ("don't cut down trees", what?).

That last one about "do not enforce Islam" is especially bullshit, because there are plenty of easy-to-find Koran quotes on subjugating and/or killing non-believers, infidels, etc.
Islam is an expansionist religion, make no mistake. By and large it has no interest in co-existence.
