Following Bosnia , Dean was invited to Kandahar to swear allegiance to Osama bin Laden and join al-Qaeda . In Afghanistan he trained al-Qaeda recruits in the basics of Islamic theology , history and the essentials of religious practice . He was worried by the 1998 United States embassy bombings and asked Abdullah al-Mohaja for the religious justification . He was pointed to a 13th Century Fatwa by Ibn Taymiyyah . He researched the Fatwa which was about the Mongol invasion and their use of human shields when besieging cities , it was clear to him that this was no justification for killing civilian bystanders . He believes the concept of Jihad is changed by al-Qaeda . The target of Jihad in al-Qaeda is starting world war opposed to the West
