The Qur'an holds a central place in Islamic thought as the final revealed scripture linked to the prophethood of Muhammad (SAW). In the Islamic tradition, the belief that prophethood has ended also means that the Qur'an is understood as the final and lasting source of guidance. This study focuses on one key way the Qur'an describes itself in classical Islamic scholarship: the idea of iʿjāz al-Qur'an, or the Qur'an's inimitability or uniqueness. Using Qur'anic verses and classical interpretations, the article explores how the Qur'an presents itself as a text that challenges its audience to produce something similar in language, style, and meaning. Instead of treating this claim as a matter of belief alone, the study looks at it within its historical, literary, and theological background. It examines how Muslim scholars understood this challenge and how they used it to explain the Qur'an's unique status. Special attention is given to how the ideas of finality and inimitability are connected and how they work together in Islamic intellectual thought. By taking a careful and text-focused approach, the article explains how the concept of Qur'anic inimitability developed and how it has been discussed and defended by scholars over time. The study also adds to wider academic discussions about how the Qur'an refers to itself, how sacred texts establish authority, and how language and rhetoric are used in the study of religious scriptures.
