Musjidul-Aqsaa (Jerusalem), the environs of which We had blessed....."

Almighty Allah says in the Quran:
"Glory be to That Being Who transported his servant (Muhammad) by night from the Musjidul-Haraam (Makka) to the Musjidul-Aqsaa (Jerusalem), the environs of which We had blessed....."
(Surah Bani Israel, verse 1)

Rasoolullah (sallallahu alaihi wasallam) said:
"Do not tie your luggage (i.e. do not travel) except to three mosques: the Musjidul-Haraam, this mosque of mine (in Madinah), and Musjidul-Aqsaa."
(Bukhari and Muslim)
