It was Dr. Fadl's that first led EIJ into the Takfiri theology that allows Muslims to excommunicate other Muslims for any petty offense against Sharia and lawfully kill them in Jihad.His thesis is definitely the cause celebre of the 'Global Inc.' nature of terror. It is the concept of 'Tafkir' that tied Egyptian, Saudis, Pakhtoons and Nejadis.Using the broad definition of 'Tafkir' this book actually cemented the ideological underpinning of terror infested Alqaeda; it was this massive ideological groundwork that saw 'Asir boys' trapped in the tentacles of the organisation. He was a revisionist even in 1990 he thought that Dr. Zawahiri was rushing to take up arms against the Egyptian state before the ground was ready. So even in the midst of his involvement with EIJ he was seen as less bloodthirsty than Zawahiri and the other hotheads.
According to Fadl, Zawahiri was delighted with the result, saying, "This book is a victory from Almighty God." 'Among those who were not only sinners but apostates of Islam and deserving of death, according to Fadl, are the rulers of Egypt and other Arab countries, those who obey them, and those who participate in elections. "The infidel's rule, his prayers, and the prayers of those who pray behind him are invalid," Fadl decrees. His blood may be shed legally by true Muslims. "I say to Muslims in all candor that secular, nationalist democracy opposes your religion and your doctrine, and in submitting to it you leave God's book behind." Other Muslims who are actually infidels include anyone employed by the government, the police, and the courts, and anyone who works for peaceful change instead of violent jihad. In addition, those who disagree with these ideas are also heretics and deserve to be killed.'
The equation is simple, Alqaeda terror = Islam+ wanton killing.
