From JihadWatch:
Four separate studies since 1999 all found that 80% of U.S. mosques were teaching jihad, Islamic supremacism, and hatred and contempt for Jews and Christians. There are no countervailing studies that challenge these results. In 1998, Sheikh Muhammad Hisham Kabbani, a Sufi leader, visited 114 mosques in the United States. Then he gave testimony before a State Department Open Forum in January 1999, and asserted that 80% of American mosques taught the “extremist ideology.†Then there was the Center for Religious Freedom’s 2005 study, and the Mapping Sharia Project’s 2008 study. Each independently showed that upwards of 80% of mosques in America were preaching hatred of Jews and Christians and the necessity ultimately to impose Islamic rule.
Saudi Arabia was funding Muslim radicalism in mosques and charities at the time the Sept. 11, 2001, hijackers were gathering in the United States and making contacts with Saudi nationals, according to a declassified intelligence document.
To jihad watchers, the paper confirms their charges that the Saudi government and its wealthy citizens fund extremist teachings in America. To this day, the kingdom is pressing its harsh Wahhabi Sunni Islam on American Muslims as it seeks to spread Islam around the world, they say.
