Die sieben kufischen Koranfragmente, die im 18. Jh. in die Königlische Bibliothek gelangten (Cod. Arab. 36, Cod. Arab. 37, Cod. Arab. 38, Cod. Arab. 39, Cod. Arab. 40, Cod. Arab. 41, Cod. Arab. 42) bilden den Gegenstand der ersten paläographischen Untersuchung zur arabischen Schrift im Abendland: Getragen vom Interesse an der biblischen Textkritik verfasste der Theologe und Orientalist Jakob Georg Christian Adler (1756-1834) zu den kufischen Fragmenten in der Königlichen Bibliothek seine Descriptio codicum quorundam cuficorum partes corani exhibentium in bibliotheca regia hafniensi et ex iisdem de scriptura cufica arabum (Altona 1780) mit Angaben zur Geschichte der arabischen Schrift, Reproduktionen der Handschriften und Vergleichen zwischen dem arabischen Korantext der Fragmente und der arabischen Druckausgabe des Korans des Abraham Hinckelmann (Hamburg 1694).
