This paper investigates the representation of voice and the concept of Islamic feminism in Brick Lane (2003) by Monica Ali is a British-Pakistani writer of Bangladeshi and English descent. It examines how the protagonist, Nazneen, navigates across the cultural expected new cultural conditions imposed on her as a Bangladeshi immigrant living in London. By focusing exclusively on Nazneen's journey, the present research highlights the features and stages of development that occur in the personality of Nazneen within the frame of Islamic feminism. This certainly determines the course of her experience with alternative identity, freedom and oppression in the new homeland. As an intellectual critical reference, Islamic feminism is applied here to criticize and reevaluate the cultural misinterpretations of Islam that are often used to limit and control women's roles, both in domestic and public spheres. The analysis employs Stuart Hall's Representation Theory to investigate Monica Ali's portrayal of the intersection between religion and culture. The paper argues that the oppression experienced by Muslim women does not stem from Islam itself but rather from patriarchal and cultural practices within their communities. Through a detailed examination of the novel, this study contributes to feminist discourse, literature can be a platform for serious critical discussion and can, by necessity, reshape the transformation of Nazneen's character highlights the potential for self-empowerment and demand for female rights within the framework of Islamic feminism.
