Frank Herbert's 1965 sci-fi novel "Dune" contains quite a few Islamic themes, most notably that of "jihad," from the Butlarian Jihad against thinking machines to Muad'Dib's own interplanetary jihad.
But as pointed out in the excellent CBC "Ideas with Paul Kennedy" episode "The Struggle Over Jihad," this is a muddied concept in our modern age. The Arabic word itself means "struggle," and does not inherently imply violence. Certainly, notions of both defensive and (rarely) offensive jihad exist in Islamic tradition, but extremist groups such as ISIS -- and Western coverage of their exploits -- have ushered a narrow, radicalized notion of jihad into the global mindset.
As the Ideas episode explores, the jihad issue illustrates an ongoing disconnect in the Islamic world -- an Internet-age conflict between learned, institutional clerics and self-appointed religious leaders. At the time of Herbert's writing, however, "jihad" had yet to become so twisted. This was the 1960s, before Guerrilla jihadism sprouted from the Soviet War in Afghanistan, so Herbert's usage of the term would seem to imply a more genuine struggle for human improvement and, in its more combative elements, an armed resistance against oppression.
Khalid Baheyeldin assembled a wonderful dictionary of Islamic terms in Frank Herbert's "Dune," which you can find right here. Specifically, however, he shares the following about jihad:
Consider it just another rich layer of meaning in one of science fiction's most tantalizing tomes. The struggle against thinking machines, for instance, was surely meant to be as much a spiritual movement as it was an act of armed rebellion -- and likewise with the galactic rise of Muad'Dib.
