This book examines whether the Islamic hadith tradition acts as a practical rival to the Qur’an, potentially overriding its legal and theological authority. The author argues that a "Great Inversion" occurred where later narrated reports began to govern the interpretation of revelation, rather than being judged by it. By distinguishing between direct contradiction, legal override, and theological distortion, the text challenges the traditional reliance on chain-of-transmission authenticity alone. It asserts that the Qur’anexplicitly defines itself as a complete and sufficient criterion for truth, making any co-binding secondary archive a structural threat to its supremacy. Ultimately, the work calls for a Qur’an-centered reordering of authority to protect divine transcendence and the integrity of the Messenger.
