Does Sauron have any dialogue in any of the books?

Question

In The Lord of the Rings film adaptions, you can hear Sauron's voice at some points but it's often hard to hear it very well. You can also hear him quite clearly in The Lego Batman Movie, although I doubt that's canon...

But as far as I can remember none of his dialogue is ever in any of the books. It might say that he said something, but I don't think it ever had what he said verbatim in quotes like an actual piece of dialogue. For example, I'm not looking for

Sauron said to do it.

but an actual piece of dialogue like

"Do it," said Sauron.

Are there any such examples?

Answer 1

When Pippin... um... 'borrows' the Palantir taken from Orthanc, he hears (for lack of a better word) Sauron say the following in his head:

“Tell Saruman that this dainty is not for him. I will send for it at once. Do you understand? Say just that!”

And when Pippin is shaken out of the trance-like stupor caused by the Palantir, he says:

“It is not for you, Saruman! I will send for it at once. Do you understand? Say just that!”

Answer 2

Sauron speaks in The Silmarillion

Thus Gorlim was ensnared; and taking him to their camp they tormented, seeking to learn the hidings of Barahir and all his ways. But nothing would Gorlim tell. Then they promised him that he should be released and restored to Eilinel, if he would yield; and being at last worn with pain, and yearning for his wife, he faltered. Then straightaway they brought him into the dreadful presence of Sauron; and Sauron said: 'I hear now that thou wouldst barter with me. What is thy price?'

And Gorlim answered that he should find Eilinel again, and with her be set free; for he thought Eilinel also had been made captive.

Then Sauron smiled, saying: 'That is a small price for so great a treachery. So shall it surely be. Say on!'

Now Gorlim would have drawn back, but daunted by the eyes of Sauron he told at last all that he would know. Then Sauron laughed; and he mocked Gorlim, and revealed to him that he had only seen a phantom devised by wizardry to entrap him; for Eilinel was dead. 'Nonetheless I will grant thy prayer,' said Sauron; 'and thou shalt go to Eilinel, and be set free of my service.' Then he put him cruelly to death.

and in the Akallabêth

And Ar-Pharazôn said: 'Who is the Lord of the Darkness?'

Then behind locked doors Sauron spoke to the King, and he lied, saying: 'It is he whose name is not now spoken; for the Valar have deceived you concerning him, putting forward the name of Eru, a phantom devised in the folly of their hearts, seeking to enchain Men in servitude to themselves. For they are the oracle of this Eru, which speaks only what they will. But he that is their master shall yet prevail, and he will deliver you from this phantom; and his name is Melkor, Lord of All, Giver of Freedom, and he shall make you stronger than they.'

Another things that we know Sauron said, verbatim, according to The Lords of the Rings (although it does not appear as direct dialogue in the novel) is:

Ash nazg durbatulûk, ash nazg gimbatul, ash nazg thrakatulûk, agh burzum-ishi krimpatul.

At the Council of Elrond, Gandalf states that those were the very words that Sauron spoke into minds of the other wearers of the great rings at the moment when he donned the Ring of Doom.

Out of the Black Years come the words that the Smiths of Eregion heard, and knew that they had been betrayed:

One Ring to rule them all, One Ring to find them, One Ring to bring them all and in the Darkness bind them.

Presumably, Gandalf learned this at best third-hand, having heard it from Cirdan, Elrond, or Galadriel, who would, in turn, have learned it from Celebrimbor or the other smiths of Hollin, at the time when the three rings were hidden away. However, despite the story being hearsay, there is no reason to doubt the accuracy of Gandalf's account.
