Dr. Mustafa Mahmoud takes us on a journey through the pages of his book “My Journey from Doubt to Faith”. This journey begins in that “gray zone” where people often feel lost and confused. He tells us about the Creator, discusses the various conflicting ideas that surround us, then moves on to the concept of the body and its unique characteristics. He explores the concept of the soul, its complexity and mystery. He also discusses the concept of eternal justice and explains his perspective on the idea of punishment. At every stage of this journey, we see how Mustafa Mahmoud reaches the pinnacle of his spiritual development. This inspires us all. Even though “human beings are born alone, die alone, and reach the truth alone”, this book can still illuminate our thoughts, as it was written by a thinker who went through many stages and transformations during his life.
