At least according to one Al Qaeda imam:
So who is this guy?
WASHINGTON — One of Al Qaeda's senior theologians is calling on his followers to end their military jihad and saying the attacks of September 11, 2001, were a "catastrophe for all Muslims."
In a serialized manifesto written from prison in Egypt, Sayyed Imam al-Sharif is blasting Osama bin Laden for deceiving the Taliban leader, Mullah Omar, and for insulting the Prophet Muhammad by comparing the September 11 attacks to the early raids of the Ansar warriors. The lapsed jihadist even calls for the formation of a special Islamic court to try Osama bin Laden and his old comrade Ayman al-Zawahri.
The disclosures from Mr. Sharif, also known as Dr. Fadl and Abd al-Qadir ibn Abd al-Aziz, have already opened a rift at the highest levels of Al Qaeda. The group's deputy, Ayman al-Zawahri, a former associate of the defecting theologian in Egypt, personally mocked him last month in a video, remarking that he was unaware Egyptian prisons had fax machines. Meanwhile, leading Western analysts are saying the defection of Mr. Sharif indicates the beginning of the end for Al Qaeda.
Oh, Senator Reid... do you still think the war is lost? Senator Edwards, is the war on terror still a bumper sticker?
Mr. Sharif, currently serving a life sentence in an undisclosed Egyptian prison, wrote in the 1980s two of the modern seminal texts for Sunni jihadism and in particular Al Qaeda, in "Fundamental Concepts Regarding Jihad" and "The Five Ground Rules for the Achieving of Victory or Its Absence." Those books are scholarly justifications, citing the Koran and Hadiths, for joining a war against Muslim apostates such as the Egyptian ruling class and for a broader jihad against the far enemy of America.
