Jerusalem in the Qur'an?

I read that the Qur'an does not mention Jerusalem. Israel's former Prime Minister Menachem Begin said, "While Jerusalem and Zion are mentioned over 800 times in the Jewish Bible, the holy city is not mentioned even once in the [Qur'an]." I am curious if this his claim is accurate. Does the Qur'an mention Jerusalem at least once? If so, what are the major passages in the Qur'an that do mention the city? I am not trying to offend anyone or make a point, I am simple trying to learn the facts.
