A mosque located on the Haram Al-Sharif (The Noble Sanctuary) in the Old City of Jerusalem and adjacent to the Al-Aqsa Mosque and Western (or Wailing) Wall. Its significance stems from the Prophet Muhammad’s night journey and ascension into heaven from the rock over which the Dome of Rock now lies, commemorated in Surah 17 verse 1 of the Qur’an. A mosque was first built on that site by Umar Bin Al Khattab, the second caliph of Islam, in the year 638 CE, and another was built in its place in 691 CE.
