The Patriarch invited him to pray in the Church of the Holy Sepulchre, but he preferred to pray outside its gates, saying that if he accepted, later generations of Muslims might use his action as an excuse to turn it into a mosque. Above is the mosque built on the spot where Omar did pray. According to Islam, man is not born in 'onginal sin'. He is God's vicegerent on earth.
Every child is born with the fitra, an innate disposition towards virtue, knowledge, and beauty.
Islam considers itself to be the 'primordial religion', din al-hanif, it seeks to return man to his original, true nature in which he is in harmony with creation, inspired to do good, and confirming the Oneness of God. Christians and Jews are called People of the Book. Muslims are asked to call upon the People of the Book for common terms, namely, to worship One God, and to work together for the solutions of the many problems in the society. Christians and Jews lived peacefully with Muslims throughout centuries in the Middle East and other Asian and African countries. The second Caliph Umar, did not pray in the church in Jerusalem so as not to give the Muslims an excuse to take it over.
