Following the 1981 assassination of the President of Egypt, Anwar Sadat – who had signed a peace treaty with Israel two years earlier – thousands of Egyptian Islamists were rounded up. These included Zawahiri, who was charged with smuggling weapons, but not Al-Sharif who fled the country, In Pakistan Sharif worked with
Ayman al-Zawahiri to rebuild Egyptian Islamic Jihad in exile. In the mid-eighties, Sharif is thought to have become
Egyptian Islamic Jihad’s emir, or chief. Al-Sharif denies this, saying that his role was merely one of offering "Sharia guidance." Zawahiri, "whose reputation had been stained by his prison confessions", handled "tactical operations." Al-Sharif impressed other jihadis with his encyclopedic knowledge of the Koran and the Hadith. Sometime in the early 1990, Al-Zawahiri and Al-Sharif fell out over questions of strategy and tactics. Al-Sharif opposed Islamic Jihad's joining another Islamist group,
al-Gama'a al-Islamiyya, in its
terror campaign against Egyptian government and foreign tourists in Egypt saying, "this is senseless activity that will bring no benefit." "Al-Sharif believed that violent attacks were futile, and instead advocated slow and steady infiltration into the structure of the state, but the group as a whole decided otherwise." After two unsuccessful bombing attempts "members of Al Jihad demanded that their leader resign. Many were surprised to discover that the emir was Fadl." Al-Sharif "willingly gave up the post", and Zawahiri became the official leader as well as leader of tactical operations. Before he left Sudan, however, Al-Sharif gave a copy of his finished manuscript to Zawahiri, saying that it could be used to raise money.
The Compendium of the Pursuit of Divine Knowledge Al-Sharif's second book was more than a thousand pages long and its author used the pseudonym Abdul Qader bin Abdul Aziz. It opens with the assertion that: "A man may enter the faith in many ways, yet be expelled from it by just one deed." Despite Al-Sharif's complaints about the al-Gama'a al-Islamiyya bombing campaign, his book defined Islam narrowly and
takfir very broadly. 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. According to Fadl, Zawahiri was delighted with the result, saying, “this book is a victory from Almighty God." But Zawahiri also edited the book before publishing it, removing "a barbed critique of the jihadi movement" and specific organizations and individuals – including
al-Gama'a al-Islamiyya (the Islamic Group) with whom Zawahiri was attempting to engineer a merger – and changing the title to
Guide to the Path of Righteousness for Jihad and Belief. Al-Sharif became furious with Zawahiri when he found this out, refusing to accept his apology and telling
Al Hayat, "I do not know anyone in the history of Islam prior to Ayman al-Zawahiri who engaged in such lying, cheating, forgery, and betrayal of trust by transgressing against someone else's book." ==Leaving Islamic Jihad==
