Remember: The Quran is written in Arabic, though most extremist actors are only capable of reading Farsi (if that). While the Quran has been translated into Western languages the clerics (for a catch all term) limit the availability of translations in some countries... Why? Because much like churchmen of the middle ages, they understand that reading the gospel/words of the prophet provide power over those who cannot read and interpret for themselves.
