This study conducts a comparative examination of the role of intertextuality in the story of Abraham and Lot in the Qur’an and the Old Testament. The main research question concerns how, despite narrative and thematic overlaps, the two texts differ in their approach to intertextuality, and how these differences affect the theological and structural objectives of each text. The significance of the study lies in revealing the stylistic and semantic connections of religious texts and providing a new basis for interfaith dialogue and understanding the re-creation of sacred texts. The research employs a qualitative, descriptive-analytical method based on the theoretical framework of intertextuality (Julia Kristeva and Gérard Genette). Data were collected and interpreted through the analysis of Qur’anic verses in the order of revelation and relevant chapters of the Book of Genesis. The findings indicate that both texts utilize internal and external intertextuality to achieve narrative coherence: the Qur’an with dispersed narratives emphasizing faith, obedience, and divine punishment, and the Old Testament with a historical structure focusing on genealogy and divine covenants. The Qur’an re-creates or revises certain narratives, such as Abraham’s sacrifice and Lot’s prophethood. The results suggest that the Qur’an employs intertextuality with a universal and ethical guidance perspective, while the Old Testament uses it to reinforce ethnic identity, both aiming to ensure coherence and convey their messages. The originality of this study lies in analyzing the story according to the order of revelation and paying particular attention to the stylistic and musical dimensions of intertextuality.
