This document is the introduction to a booklet titled "Just One Message!" that seeks to convey the singular message delivered by all prophets - that God is one and should be worshipped alone. It provides an overview of the booklet's contents and objectives to critically examine verses from the Bible and Quran regarding tawheed (monotheism). The author aims to demonstrate that both scriptures uphold the oneness of God and refute notions of a trinity. The document invites readers to thoughtfully consider this message and contact the author if interested in learning more about Islam.
