There have been two conquests of Jerusalem; one in the time of the Rightly Guided Caliph, by Omar bin Al-Khattab, and the other by Saladin Al-Ayyoubi. The first conquest is the Omari Conquest that was accomplished through following the plan and will of prophet Mohammed, PBUH The second conquest was at the hands of Saladin Al-Ayyoubi, implementing the plan of Imad Al-Din Zinki, where the later died before carrying it out entirely, so his son Noor Al-Din Zinki continued with his plans, and then Saladin Al-Ayyoubi followed their steps and liberated the city.
