About a month ago, I wrote about an ideology called Qutubism, which is named for its founding thinker, the Egyptian radical Syed Qutb. Qutubism is the primary ideology of Ayman Zawahiri, Bin Laden's "number two", and was a major influence on Abdullah Azzam, who served as Bin Laden's teacher and mentor (Zawahiri is Egyptian and Azzam was Palestinian).
I argued that Qutubism is an ideology that is distinct from Wahhabism and has goals that are different from, and in fact often directly opposed to, those of the Wahhabi establishment in Saudi Arabia. This is set out in more detail in the other blog entry.
As a follow-up to this, you may wish to take a look at The Wahhabi Myth - Salafism, Wahhabism, Qutbism. This is the website for a recently-published book which is sponsored by organizations that are closely linked to the Wahhabi establishment. If you're interested in this question, I encourage you to check out the site, read the materials excerpted there, and make your own judgment on the matter.
As I wrote in the comments of the other blog entry:
My purpose in posting this entry was not to promote either Wahhabism or Qutubism. My purpose was simply this: very often the two groups are treated as the same. They are not. They are two different groups with different, and sometimes opposing, aims. A policy based on the assumption that they are the same or that they share the same aims is a policy based on an error. In order to determine the best course of action and the best policy we need to have an accurate understanding of the situation.
