In this study, the concept of Islam and the "Other" have closely been examined in the postcolonial context after September 11 in the novels The Reluctant Fundamentalist by Mohsin Hamid and The Terrorist by John Updike. As protagonists in the chosen works are postcolonial characters and their being exposed to otherization due to their religious and ethnic identities in American society has made it possible to examine the concept of Islam and the "Other" profoundly in these works. In a postcolonial or Neo-Colonial World, owing to the effects of migrations to Europe and the U.S.A, multicultural societies have occurred and Muslim immigrant families living there have had cultural, religious, and social integration problems and especially after September 11 attacks, with the help of the visual and written media, Fundamentalism and Islam phobia have risen, and Muslims have been subjected to a sort of racism and otherization in the society. In today's world, racism events have still happened in Europe and the U.S.A. and Islamic values and places have been targeted in spite of the Muslims' position in society.
