The important thing is for the reader to know the truth and to consider and understand the personal story, I do not appeal to some readers. What is contained in this book is the common denominator between Islam and Christianity, both of which are the most influential religions in the world, and there are a large number of adherents from all over the world and all peoples, as well as religions with very close religious affiliations. In terms of religious rehearsals, I will be recounting two of my own personal experiences. I sincerely hope that, by God's will, this book will truly help you who are searching for the true religion.
