This study revolves around the jihad ideas of 'Abd Allah 'Azzam - an iconic figure in the study of militant jihad in the 20th century, history of Afghan jihad against the Soviet Union, Al-Qaeda and current threat of terrorism.This study has several objectives: to render an in-depth description of his ideas by way of a review of his writing, hitherto little referenced in the literature, to identify how these ideas have inspired so many to participate in militant jihad in the Soviet-Afghan war, and indeed elsewhere, to highlight the internal contradictions and inconsistencies in 'Azzam's ideas, and to juxtapose these ideas with contemporary jihadism, to identify specific aspects of 'Azzam's ideas in order to extract key lessons for counter-ideology work within the framework of counter-terrorism. some of 'Azzam's jihad ideas diverge from dominant ideas held by current jihadist groups like Al-Qaeda and these could potentially be used to counter contemporary jihad ideas and practices of jihadists.
