Long live the fighters of Muad'Dib! I could swear that there was a line in the movie "Dune" (the David Lynch one) that said, "Long live jihad! Long live the fighters of Muad'Dib!" and a friend of mine who's a fan of that film swears so up and down, but she claims it's been deleted out of broadcast showings of the movie since 9/11. I don't know about that, to be honest. But would anyone here know if that line was from the movie, or from the book? Or am I transposing one of the innumerable uses of the word 'jihad' used throughout "Dune"?

RESPONSE OF TWENTY THOUSAND VOICES
	Bi-la kaifa.

		REVEREND MOTHER RAMALLO
	And now the prophecy...

Silence...then a powerful low organ NOTE resounding
in the cavernous space.

      REVEREND MOTHER RAMALLO (CONT'D)
	He will come...the voice from the outer
	world, bringing the holy war, the Jihad,
	which will cleanse the Universe and bring
	us out of darkness. He will have been born
	of a Bene Gesserit mother.

The Reverend Mother continues speaking of the
Prophecy, but we do not hear it. The huge wind organ
BLOWS louder and louder, obscuring her voice.

The picture FADES.

Yes, the religion in DUNE was a quasi-Islamist religion, but it was not really based in Mohammed just as the Orange Catholic Bible was not strictly Christian.

The Butlerian jihad against the robots that enslaved humanity eventually freed the humans.

The Fremen weren’t supposed to be muslims per se, but every group of people in the Dune books were modeled on existing or historical groups. The planet Arakis and the Fremen are based upon Saudi Arabia, fighting to get control of their own oil (spice) from the British.
