This book is a brief summary to re-introduce people to the roots of their faith (the belief in one God and unifying Him in worship) through relevant verses from the Qur’an and other religious scriptures. It is an attempt to demonstrate to all open-minded people and truth-seekers that what was sent by God to all people through all messengers throughout history is one unique message (i.e. Pure Monotheism). All God’s pious messengers endeavored to guide their people to the truth. But many people chose to follow their own understandings and interpretations, and thus went far from the prophetic teachings.
