Azzam is thought to have had influence on jihadists such as al-Qaeda with the third stage of his "four-stage process of jihad". This third stage was "ribat," defined as "placing oneself at the frontlines where Islam was under siege". This idea is thought to reinforce militants' "perception of a civilizational war between Islam and the West". His son Huthaifa Azzam, who assumes his father's legacy, on the other hand, says that al-Qaeda's methods of targeting civilians in the West or elsewhere would have been rebuked by Azzam, as would have been the use of kidnappings and beheadings.
