The question has haunted the UCLA Islamic law professor since April, when he says a bullet whizzed past his ear and lodged in a book as he was standing near his living room bookshelf in front of his open front door. His fears intensified this month, after a news report in the Anaheim-based Al Watan newspaper and other Arabic-language media carried what Abou el Fadl calls a "solicitation of murder" against him... {He is} one of the nation's most prominent critics of Saudi Arabia's puritanical practice of Islam known as Wahhabism...members of the FBI's joint terrorism task force, which independently picked up the news report, were so concerned that they visited Abou el Fadl recently to warn him to take security precautions, the scholar said in an interview last week. He added that he has also met with FBI agents and University of California police, who have begun implementing heightened security measures..."I've received so many death threats, and I've never had an impending sense of doom," he said. "This time, we're taking it more seriously."..."If they scare me into silence, they will have succeeded," he said. "I'm not going to give them that victory."
