This appears to be something that may be debated for a long time, depending upon whether people who were there can (or will) ever produce an actual audiotape - and to what extent we would even be able to trust the authenticity of such an audiotape.
The original article is reprinted at the Ha'aretz web site dated Tue., November 30, 2004 Kislev 17, 5765, but if you format it for printing it says "Last update - 02:45 24/06/2003":

The quote is repeated many more places, easily found on a google.com search
...
"Abbas said that at Aqaba, Bush promised to speak with Sharon about the siege on Arafat. He said nobody can speak to or pressure Sharon except the Americans.
According to Abbas, immediately thereafter Bush said: "God told me to strike at al Qaida and I struck them, and then he instructed me to strike at Saddam, which I did, and now I am determined to solve the problem in the Middle East. If you help me I will act, and if not, the elections will come and I will have to focus on them.""

Press Briefing by Ari Fleischer
The James S. Brady Briefing Room
12: 50 P.M. EDT
(at the end of the briefing)...
Q: Ari, staying on the Middle East. Prime Minister Abbas today, according to Ha'aretz, told a meeting with Hamas -- he quoted the President and at that point, during that meeting, he suggested that the President conveyed that now is the time to move forward or else I'm going to focus on the election, or the election is coming up shortly. Can you tell me whether or not --
MR. FLEISCHER: Yes, somebody else asked me about that quote. I never heard the President say it. He certainly didn't say it in the trilateral meeting that I attended, and I'm not aware of any other conversation in which he said it.
Q: So there is no deadline attached --
MR. FLEISCHER: You're seen the President on this issue. He's focused on it all the time. And he will be focused on it now, he'll be focused on it a year from now, he'll be focused on it two years from now.
Q: Part of the same quote, Prime Minister Abbas suggested the President said that God spoke to him about al Qaeda and spoke to him about Saddam. Is that a stretch? Is there anything to that? How would you characterize that part of the --
MR. FLEISCHER: It's beyond a stretch. It's an invention. It was not said.
Q: I was going to ask on that very same point. Just to be clear, to quote, as reported by Ha'aretz, is not true, didn't come up in the meeting?
MR. FLEISCHER: Hasn't become true since I just told Ken it wasn't. (Laughter.)
Q: Well, a few seconds passed there.
