This paper attempts to provide an ideological approach within a critical discourse analysis (CDA) in order to investigate the Islamic discourse and to trace the ideological devices in Amr Khalid's sermons. In so doing, this paper tries to show how language, employed in Khalid's sermons, reflects the common conceptual structures and interrelationships between him and his audience. The study is also concerned with uncovering certain forms of ideological disguises and demystifying power relations in discourse within specific context. This approach makes it possible to explore the tension between idealism and pragmatism, the conflict between "us" and "them", and the other aspects of ideologies existing in the Khalid's sermon.
