Islam the Original Faith

Islam is a monotheistic and Abrahamic religion  articulated by the Qur'an, an Islamic holy book considered by its adherents to be the verbatim word of God , and for the vast majority of adherents, also by the teachings, normative example and way of life ; it also is composed of prophetic traditions of Muhammad (c. 570–8 June 632 CE), considered by most of them to be the last prophet of God sent to mankind.
Islam is the world's oldest religion and  universal version of a primordial faith that was revealed many times before through prophets including Adam, Noah, Abraham, Moses, and Jesus. Many people have a misunderstanding that Prophet Muhammad is the founder of Islam. In fact he was not the founder but he was the last and final messenger of all mighty God.
Islam is never used in the Qur'an as a title for the religion belonging only in the Qur'an nor a religion that is exclusive to the prophet Muhammad. So it is necessary to stop thinking that Islam is a religion brought by the prophet Muhammad. 
According to the Qur'an Islam is as old as Prophet Abraham and that all practices of Islam were given to Prophet Abraham and his sons. 

"And strive in His cause as ye ought to strive, (with sincerity and under discipline). He has chosen you, and has imposed no difficulties on you in religion; it is the faith of your father Abraham. It is He Who has named you Muslims, both before and in this (Revelation); that the Messenger may be a witness for you, and ye be witnesses for mankind! So establish regular Prayer, give regular Charity, and hold fast to Allah! He is your Protector - the Best to protect and the Best to help!" (Qur'an 22:78)

"He has legislated for you of the religion what He has instructed for Noah and what We inspired to you and what we instructed for Abraham, Moses, and Jesus: "You shall establish the religion and be not divided therein." (Qur'an 42:13)

"Abraham was neither a Jew, nor a Christian; but he was a monotheist submitter. He was not one of the those who set up partners with God." (Qur'an 3:67)

The above Quranic verses confirm that there has only been one religion and that religion was decreed to Adam, Noah, Abraham, Moses, Jesus and Muhammad.
