Plot, as a chain of organized and causally related events, plays a key role in understanding a story. Among the classifications proposed by narratologists, Norman Friedman's model—which categorizes plot into three main types (plot of fortune, plot of character, and plot of thought) along with their subgenres—stands as one of the most comprehensive approaches. Adopting a descriptive-analytical method, this study aims to analyze the role and function of plot in Najib Mahfouz's narrative style, using his short story collection "Duniya Allah" as a case study. The central hypothesis posits that applying Friedman's tripartite model to non-Western texts, including Arabic fiction, can contribute to the development of intercultural narratological frameworks and reveal new dimensions of the model's flexibility. Data analysis indicates that Friedman's model is effectively capable of explaining the narrative complexities and thematic diversity within this collection. All three types of plot presented in Friedman's model are employed with comparable frequency in this story collection, demonstrating a significant causal relationship between Friedman's plot classification and Mahfouz's recurring themes, such as the conflict between tradition and modernity and social determinism. This correlation stems from Mahfouz's orientation towards psychological analysis of characters and his use of plot as a tool for critically reflecting upon the issues of Egyptian society.
