That is what I posted on the Muslims and Christians thread:
Why is the Church of the Holy Sepulchre important to Muslims?
When the prayer time came, the Archbishop of Jerusalem, Sophronius, invited the Caliph Umar, to pray at the Church of the Holy Sepulchre, Christianity's holiest site. ... The Mosque of Umar still stands next to the Church of the Holy Sepulchre as a reminder of the strong Muslim-Christian bond in the Holy Land.
While Al Husseini's family holds the key, the Nuseibeh family is charged with the physical work of opening and closing the church's door, a duty they trace back to 637 when the caliph Omar first brought Islam to Jerusalem, explained Wajeeh Y Nuseibeh, 67, who was sitting on the bench next to Al Huseini.28 Nov 2016
