The current study explores the devastating aftershocks and identity crises caused by 9/11. It furthermore, presents the upheavals through two different forms of literature: The Reluctant Fundamentalist by Mohsin Hamid and the cinematic film Khuda Kay Liye by Shoaib Mansoor. The study employs a post-colonial lens, utilizing the concept of marginality to examine identity crises and the traumatic aftermath of 9/11. In addition, the study highlights the main characters of both the literary forms: novel and film, demonstrating how they face marginalization at various levels—cultural, religious, and international. The background of the study encompasses the Afghan-Russian war in 1979 and the 9/11 attacks, which profoundly affected Afghanistan and northern Pakistan, fueling terrorism and raising questions about identity. Religious figures, as the research uncovers through the character of Changez in The Reluctant Fundamentalist, were often labeled as terrorists. On the other hand, Mansoor, Maryam, and Sarmad are marginalized in Khuda Kay Liye. Mansoor faces racial prejudice in the USA, while Sarmad and Maryam encounter religious extremism in Pakistan. While weaving together the theme of identity crises, the study adopts the framework of marginality, a significant aspect of post-colonial literature. With a clear understanding of the issues, the study utilizes post-colonial theory, using Edward Said's seminal work, Orientalism. Additionally, the researcher recognizes the significance of marginality, which is central to both the genre fiction and the films The Reluctant Fundamentalist and Khuda Kay Liye.
