Ingrid Mattson has established a powerful reputation in the academic and North American Muslim communities. In a 2010 New York Times article, she was described as “perhaps the most noticed figure among American Muslim women.” She, for example, served as the President of ISNA (an admitted Muslim Brotherhood front-group) from 2006-2010, after serving as its Vice President since 2001. ISNA was named an unindicted co-conspirator in the prosecution of the Holy Land Foundation, a U.S. government-designated terrorist organization that was charged with providing material support to Hamas through local ‘zakat’ (Muslim charities).
Despite these facts, she was invited to offer a prayer during Barack Obama’s first inauguration. On a broader level, Mattson has denied the existence of terrorist cells operating in America, defended Wahhabism as a reform movement analogous to the Protestant reformation, whose Saudi clerics denounce terrorism, and has lamented the end of the Islamic Caliphate and extolled the legitimacy of Shariah law.
Similarly, when asked to recommend a work of Qur’anic commentary for Muslim youth, she cited Abul A’la Maududi. Among other things, Maududi was an Islamist academic and journalist who founded Jamaat-e-Islami, the largest Islamic organization in Asia (and designated terrorist organization by the U.S. State Department), and sister-group of the Muslim Brotherhood. He is also credited with the idea of the Shariah Islamic state governed only by the Qur’an and Sunna.
Recently, Dr. Mattson’s libel lawsuit against Canadian lawyer and terrorism expert David Harris collapsed following over a year of legal action. This is significant since Dr. Mattson launched her proceeding after Harris refused to withdraw his characterization of her as “radical” and “pro-Islamist” during an interview. Mattson ultimately agreed to have the Superior Court of Ontario dismiss her own suit, despite her claim of grave reputational damage.
