Personally, I believe the Jedi Order of the PT was hopelessly corrupt and immoral, and that Qui-Gon was working consciously or unconsciously (guided by the Force) towards the destruction of the Order. There is some small amount of evidence in the films that this was Lucas's intention at some point, but was dropped late in the process. The evidence is not entirely convincing, however, and I don't think Lucas has addressed this specific point. But the Jedi of the PT do have some notable features in common with the worldwide Islamist movement (i.e. Wahhabism, Salafism), so I think looking for Arabic language influences is worthwhile.
