Islam was the first religion in the world. The first prophet and human being created: Prophet Adam (A.S.) was a Muslim and a prophet.
All the 124,000 prophets and messengers that Almighty Allah sent, starting with Prophet Adam and ending with Prophet Muhammed, were Muslims and were teaching one thing and were guiding people toward the path of Allah.
The Jews that were at the time of Moses and were following him were actually Muslims and they were believing in the same beliefs that Islam had.
The Christians that were at the time of Jesus and were following him were actually Muslims and they were believing in the same beliefs that Islam had.
The Holy prophet Muhammed said: "I was sent to perfect the best of Morals." So the prophet came to complete the religion of Allah and add the final laws and rules that were sent and perfected the religion of Allah.
"Say, 'Anyone who opposes Gabriel should know that he has brought down this (the Qur'an) into your heart, in accordance with God's will, confirming previous scriptures, and providing guidance and good news for the believers'" (Sura Al-Baqarah (#2:97)).
So we can simply say that Islam began when the first human being was created and he was Prophet Adam and was perfected and the religion was complete with Prophet Muhammed (P.)
