This study explores the sociolinguistic evolution of the English language within the contemporary global Muslim community, focusing on the emergence of "Islamic English." As globalization de-centers English from its native Western origins, non-Arab Muslim populations increasingly adopt it as a vital medium for religious expression and identity construction. Utilizing Critical Discourse Analysis (CDA) and a qualitative case-study approach, this research examines how speakers in Indonesia, Pakistan, Turkey, and Western Muslim diasporas navigate the inherent tensions between Anglo-centric linguistic norms and Islamic values. The analysis focuses on lexical borrowing, semantic transformations of Arabic roots, and pragmatic code-mixing within digital and academic discourses. The findings suggest that Islamic English functions not merely as a passive translation tool, but as an active, translingual instrument that validates localized religious identities. Ultimately, this study contributes to the fields of World Englishes and the sociolinguistics of religion by challenging traditional "Standard English" biases and documenting the legitimacy of religious linguistic variations.
