The current study is an attempt to investigate Russian Islamic discourse as a specific type of religious discourse and the way of using code switching to manipulate communicators. In Russian Federation the Islamic community is polyethnic. RF moslems of different nationalities use in their communication two or more languages simultaneously: Arabic, Russian and native languages. The use of a particular language depends on the type of communication in the religious discourse. Communication with God through five daily prayers and reading sacred texts is possible only in Arabic; personal and group communication is usually carried out in native language; mass communication on the institutional level is carried out in Russian. Since Members of the Islamic community use different languages in different functional areas, it is possible to characterise Russian Islamic discourse as diglossic (according to J.Fishman [1]). Typical for diglossia code switching becomes one of the means of persuading and manipulation in religious discourse.
