Prophet Muhammad(Peace be upon him) was NOT the founder of islam

MISCONCEPTION: Prophet Muhammad (Peace be upon him) was the founder of Islam. We read it even in text books.
REALITY: Prophet Muhammad (Peace be upon him) was NOT founder of any religion. He was just last and final messenger of Almighty God. Someone who is last in series can not be founder of it. Never ever does Quran claim that Prophet Muhammad (Peace be upon him) brought or established any new religion. All the prophets of God gave same fundamental teachings of God. Right from first prophet i.e. Prophet Adam (Peace be upon him) to Prophet Muhammad (Peace be upon him) there have been thousands of prophet. They all gave same fundamentals.
The same religion has He established for you as that which He enjoined on Noah - the which We have sent by inspiration to thee - and that which We enjoined on Abraham, Moses, and Jesus: Namely, that ye should remain steadfast in religion, and make no divisions therein:….. Quran 42:13
We have sent thee inspiration, as we sent it to Noah and the Messengers after him: we sent inspiration to Abraham, Isma'il, Isaac, Jacob and the Tribes, to Jesus, Job, Jonah, Aaron, and Solomon, and to David We gave the Psalms. Quran 4:163
Muhammad is not the father of any of your men, but (he is) the Messenger of Allah, and the Seal of the Prophets: and Allah has full knowledge of all things. Quran 33:40
Conclusion: Religion is established by GOD and not by men. hence no man can be founder of releigion. Men can start a sect,ideology,cult etc but Only GOD will be the founder of religion.
