It is often said that "a book is known by its title." When reading the title of Sultan Al-Mousas book "Aqwam Qila," you might immediately think of God's words in Surah Al-Muzzammil: "Indeed, the rising of the night is more intense for walking and more suitable for speech." "Aqwam Qila" means the most upright of statements, and this is what I have focused on in this bookrelying on the most upright statement, which is "the word of God." This is part of a mental journey that will take you into a world of contemplation and reflection on many matters and mysteries of the Holy Quran. We will also set sail together through 11 different chapters on the most prominent atheistic and existential theories, uncovering the religious veil over certain extraordinary phenomena. We will pause to examine the most significant other religions to unveil their secrets in a youthful and different style. Furthermore, I have also made it a point in this book to answer the philosophical questions that a Muslim might secretly ask himself about the Creator, the devil, and the Quran. The chapters of the book are arranged as follows: Chapter One: The Reality of God's Existence, Chapter Two: An Insight into the Character of Iblis, Chapter Three: My Christian Colleague, Chapter Four: Why God is the Truth among Deities, Chapter Five: The Marvels and Wonders of the Quran, Chapter Six: My Journey to the Vatican, Chapter Seven: A Day with Saleh, Chapter Eight: Umm Muhjan, Chapter Nine: And a Soul and What It Is, Chapter Ten: Natural Facts and Other Extraordinary Phenomena, Chapter Eleven: The Cow, Al-Aziz, and the Ark. "Aqwam Qila" is considered one of the most important books discussing issues of atheism and existence, addressing key religious issues in various religions while also answering philosophical questions and discussing them in a simplified and understandable manner. Sultan Al-Mousa aims to close the gaps that atheists and followers of other religions exploit.
