Critics argue Imam Rauf supports suicide bombers, Iranian repression, radical clerics and adoption of sharia law by the west

Almost as controversial as the proposed Park51 Islamic community center two blocks north of Ground Zero is the man behind the project, Imam Feisal Abdul Rauf. Opponents of the "Ground Zero mosque" are building a case that Rauf is a "cynically brilliant" Islamic extremist in sheep's clothing, while supporters call him and fellow Park51 organizers "the kind of Muslim leaders right-wing commentators fantasize about: modernists and moderates who openly condemn the death cult of al Qaeda and its adherents." Who is the real Rauf? (Listen to some of Imam Rauf's controversial comments)

What's his background?

Born in Kuwait in 1948, Rauf has lived in New York since 1965, and has a physics degree from Columbia. He's been imam of Masjid al-Farah, a Sufi mosque in New York City's TriBeCa neighborhood, since 1983. Rauf has written three books on Islam and how it fits into Western society. He's married to his second wife, Daisy Khan.

Was he raised Sufi?

No. His father, Muhammad Abdul Rauf, was a more conservative Sunni Muslim who, with the support of Egypt, taught and studied at universities and mosques outside the Middle East. The elder Rauf moved his family around to England, Malaysia, and then the U.S. The exposure to different religions and Islamic traditions led Feisal to shift to the more moderate and mystical Sufi Islam.

What was Rauf best known for before the Park51 controversy?

Since the 1990s he has been heavily involved in interfaith dialogue with Christian and Jewish leaders, and has founded two nonprofits focused on building bridges between American Muslims, U.S. society, and the Muslim world: The American Society for Muslim Advancement (1997) and the Cordoba Initiative (2003). After 9/11, Rauf did sensitivity training for the FBI and has gone on four U.S.-sponsored speaking tours to the Mideast since 2007 to discuss how Islam meshes with American religious pluralism.

What's the case for him being a "stealth" extremist?

Critics say his peace-and-brotherhood talk covers up support for Palestinian suicide bombers, Iran's repressive Islamic government, radical Muslim clerics, and the imposition of Sharia law in the West. To support these charges, his detractors cite Rauf's refusal to call Hamas a terrorist group and his equating of certain U.S. actions with Islamic terrorism. The Cordoba Initiative and its Park51 project aren't about dialogue, critics say, but rather about proselytizing and spreading Islam.

Is the case persuasive?

Though a few of Rauf's speeches contain some jarring notes (see quotes below), those who have known him for a long time are surprised by the allegations. "To stereotype him as an extremist is just nuts," says the Very Rev. James P. Morton, longtime dean of the Church of St. John the Divine.
