Frank Herbert’s 1965 novel Dune and its sequels tackled a lot of big themes. The books are about ecology. They’re about journeys of self-realization through mind-altering substances. But religion is at the core of the series, since the main character Paul Atreides transforms from a teenage aristocrat into a messianic revolutionary leader of a nomadic desert tribe. And the real world religion that Frank Herbert borrows from the most is Islam. Khalid Baheyeldin, Salman Sayyid, and Sami Shah discuss why the book resonated deeply with them, despite the fact that Frank Herbert wasn’t Muslim. And Liel Liebowitz explains why the novel even spoke to him as an Israeli.
