This paper introduces the exchange of letters in early Sufism, analyses the significance of these exchanges, and examines these documents not for their general literary qualities or for theoretical discussion of appropriate conduct but, rather, for actual data relating to personal and interpersonal relationships. Furthermore, this paper emphasizes the crucial need for creating a corpus of Sufi letters and pieces of correspondence. The discussion is divided into methodological and conceptual-historical perspectives. The methodological perspective includes a survey of sources, the question of transmission, letter fragment usage by later authors, and a reconstruction attempt of the actual circumstances of these documents. The conceptual-historical perspective analyses content, rhetoric, argumentation forms, and self-representation.
