The article analyzes the reflection of aesthetic and spiritual values in Islamic art and architecture based on the Islamic worldview, the ideas expressed in the Holy Quran and religious-aesthetic thought. The study shows that Islamic art is not based solely on external beauty; rather, it is grounded in the principles of tawhid (oneness), unity, harmony, balance, geometry and symbolic meaning. The artistic principles formed by Islamic aesthetic thought are explained through examples such as the expressive power of Quranic verses, calligraphy, ornamentation, geometric compositions and mosque architecture. At the same time, the main criteria influencing the formation of Islamic identity in architecture, including beauty, unity in multiplicity, harmony and geometric order, are examined. As a result, it is concluded that Islamic art and architecture represent a unique artistic system that combines spiritual content with aesthetic form and reflects the religious and cultural values of society in the material environment.
