Almighty God (Allah in Arabic) created Hazrat Adam (AS) and sent him to the earth. He was the First Human being, first Prophet of Almighty God and the first Muslim. Later on Almighty God sent about 1,25,000 Prophets in all parts of the world and to every nation of the world for the guidance of humans. They include Hazrat Noah, Hazrat, Abraham, Hazrat Moses, Hazrat John, Hazrat Jesus Christ (May blessings of God be upon them all). Their message was One and the Same: belief in the ONENESS of Almighty God. All of them preached Islam and worship of One God.
