A Huffington Post article, the full title being 'A Saudi Psychologist on Jihadism, Clerical Elite and Education Reform':http://www.huffingtonpost.com/joseph...d&ir=WorldPost

This is a clue:
Clinical psychologist Abdullah al-Garni serves a niche clientele: recovering jihadists. He heads the mental health division at the Mohammed bin Naif Center for Counseling and Advice, a halfway house for members of Al-Qaeda and other groups who have served prison time in Saudi Arabia or at the U.S. Government-run Guantanamo Bay detention facility.


The most interesting Q&A is:
Q: How did Islam come to be used as a justification for terrorism among Saudis?
A: It is a matter of how a group of so-called clerics interpret, or misinterpret, Islam. In Surat Al 'Imran of our Holy Book, it says, "No one knows [the Qur'an's] true interpretation except God, and those who are well-grounded in knowledge say, 'We believe in it. All of it is from our Lord.'" But some clerics stop in the middle of the verse, and just say, "No one knows [the Qur'an's] true interpretation except God and those who are well-grounded in knowledge." Then they put it to you that they alone are well-grounded in knowledge, and go on to use the half-sentence as a divine mandate for their own authority. If we claim that our religion is a peaceful religion, calling for peace between nations and between religions, then these false foundations need to be addressed.
