Khalid from the Baheyeldin Dynasty blog has put together a great resource of Arabic and Islamic themes found in the science fiction novel and movie "Dune" by Frank Herbert. Please check out the link below; it is worthwhile if you have interest in science fiction and/or Arabic language.
'What is not well known are the various Islamic undertones, and Arabic etymologies that Frank Herbert put in Dune. The purpose of this article is to try to list these themes, and trace them back to whatever Islamic concept there is (if any). The following list is derived from the above linked Lexicon, with some of my own addition. I try to explain what the term means in Herbert's novel, and what possible Arabic or Islamic terms it was derived from, and their original meaning.'
