Verse 42:23 and how to interpret it, disciplines of interpreting Quran.

[CapnAwesome]

The Qur'an is a long super boring book with such loose structure and over emphasis on metaphor and poetry that it can mean whatever you want it to.

That being said, I do think you can glean some of how Muhammad (piss be upon him) interpreted it based on his own actions in his life, in which case ISIS seems like the closest to how he lived his life.
