The epistles and testaments of the combatants during the Sacred Defense era are highly significant as authentic documents that convey their ideals and messages to future generations and depict the political, social, cultural situations of both frontlines and hinterlands. They constitute a part of the written cultural legacy of the Sacred Defense. These epistles, which reflect the beliefs and aspirations of the combatants, not only influence various segments of society and provide spiritual gratification for the reader, but also contribute to advancing historical and sociological studies. They also contain creative and innovative elements that have been overlooked and neglected in most examinations of the written heritage of the Sacred Defense. Therefore, this research aims to explore the artistic and innovative aspects of the epistles and testaments of the combatants from Qom province between 1980-1988 - which have not been printed yet - using a descriptive-analytical method. These epistles and especially testaments have a specific structure at a general level, consisting of introduction, contextualization, testament text, conclusion, name and signature. From a literary perspective, various literary devices have been employed in their text. The culture of Ashura, velayat-e faqih (guardianship of jurist), and safeguarding the achievements of the revolution are among the most prominent themes that dominate their content. One of the outcomes of this research is to introduce epistles whose authors have written them in a distinctive way from others by spending time and taste and often in their leisure time. Some examples of artistic and innovative works in this section are occasional correspondence, use of foreign or second languages, versification, multicolor writing, application of literary devices, calligraphy, painting, appropriation of trivialities, and various forms of name writing.
