“Do they now have fax machines in Egyptian jail cells?” he asked. “I wonder if they’re connected to the same line as the electric-shock machines.” This sarcastic dismissal was perhaps intended to dampen anxiety about Fadl’s manifesto—which was to be published serially, in newspapers in Egypt and Kuwait—among Al Qaeda insiders. Fadl’s previous work, after all, had laid the intellectual foundation for Al Qaeda’s murderous acts. On a recent trip to Cairo, I met with Gamal Sultan, an Islamist writer and a publisher there. He said of Fadl, “Nobody can challenge the legitimacy of this person. His writings could have far-reaching effects not only in Egypt but on leaders outside it.” Usama Ayub, a former member of Egypt’s Islamist community, who is now the director of the Islamic Center in Münster, Germany, told me, “A lot of people base their work on Fadl’s writings, so he’s very important. When Dr. Fadl speaks, everyone should listen.”
