When Umar signed Jerusalem Treaty considered as the first charter of religious freedomUmar was given a tour of Jerusalem, including the Church of the Holy Sepulchre. That would change during the caliphate of Umar ibn al-Khattab, the second caliph of Islam. Having heard of such a condition, Umar ibn al-Khattab left Madinah, travelling alone on a camel and one servant. The Treaty of Umar allowed the Christians of Jerusalem religious freedom, as is dictated in the Quran and the sayings of Muhammad ﷺ. Throughout the remainder of Umar’s caliphate and into the Umayyad Empire’s reign over the city, Jerusalem became a major center of religious pilgrimage and trade.
