In the Pahlavi documents we find a sequence of characters that are commonly transliterated as 〈nc〉, representing Middle Persian namāz `reverence’. The vocalisation as namāz, a word most commonly found in the greeting formulae of letters, is not disputed. The question is rather whether these characters stand for a phonetic, albeit abbreviated, spelling of namāz or whether they constitute an abbreviation that developed out of the heterogram 〈ʿSGDH〉.
In light of recent developments in the field and the rather sizeable evidence, I will revisit the arguments brought forward thus far and propose a new interpretation.
This very interesting volume has an article by Jairus Banaji On the Identity of Shahrālānyōzān in the Greek and Middle Persian Papyri from Egypt:

Historians have long lamented the lack of contemporary documentary sources for the Islamic middle ages and the inhibiting effect this has had on our understanding of this critically important period. Although the field is richly served by surviving evidence, much of it is hard to locate, difficult to access, and philologically intractable. Presenting a mixture of historical studies and new editions of Greek, Arabic and Coptic material from the seventh to the fifteenth century C.E. from Egypt and Palestine, Documents and the History of the Early Islamic World explores the untapped wealth of documentary sources available in collections around the world and shows how this exciting material can be used for historical analysis.
