Just as isaac was born of lack of faith, of abraham doubting God and trying to have a son outside his miracle, so does islam come from man's attempt to reach god on his own, of denying Christ as the son of God and through jewish laws and false prophecies form their on failed religion

And i say failed, because re-ligion means to re-link, to reconnect with God. And islam fails at linking man woth God, instead driving him further away
