Three is Not One: The Search for God's Truth is a famous book written by Md. Ahasan Habib Rifat. In this book, he, as a researcher and author, takes readers on a brave and fresh journey. He is a Muslim researcher who studies religion by comparing different beliefs. In this book, he talks about one of the most important but hard-to-understand Christian beliefs — the Trinity. In simple words, with logic and respect for Jesus (peace be upon him), he explains that God is one, not three. Using the Bible and the Quran, he shows that all the prophets believed in one God. This book is not just for argument; it wants to make people think and awaken. Rifat speaks in a way that is often simple, sometimes funny, and sometimes emotional. He asks everyone to think for themselves and search for the truth. Whether you are Christian, Muslim, or just curious, this book will give you a chance to question what you have learned and show you a simple truth: There is only One God, and He has no equal.
