François Déroche schreibt zu dem Fragment (vgl. The Abbasid Tradition, London 1992, p. 69): " 21 / Single folio / 9th century AD / 20.8x27.8 cm, with 6 lines to the page / Material Parchment; the recto is the hair side / Text area 12.9x22.5 cm / Script Style D.I / Accession no. KFQ68 / This folio is a beautiful example of one of the most impressive calligraphic styles of the Abbasid period. Perfect mastery of the pen is suggested by the horizontal lines, which are subtly underlined by the use of mashq, and by the precision of the crescent-shaped lower return of independent alif. This mastery explains the fascination exercised by the D.I style in its time, a fascination that is shown by the numerous variations upon it. Only a limited number of manuscripts attain this sober beauty, and many of these were bequeathed to mosques, as in the cases of the Qurʾans of Amjur and ʿAbd al-Munʿim (Rice 1955, p. 2; Arberry 1967, no. 16; James 1980, p. 20; Déroche 1983, pp. 147-9; and Déroche, forthcoming). / The distinctive letters of D.I are the independent form of alif and the final form of nūn, whose head is somewhat fatter than the vertical part of the body and whose lower return curves slightly upward. The medial form of ʿayn, independent lām-alif and final qāf should also be noted. / This folio contains Sūrat al isrāʾ (XVII), verses 53-5. The text is written in black ink, with diacritical strokes which are also in ink. The vocalization is indicated by red dots; the green dots seem to correspond to sukūn. The end of every vers is marked by a gold 3.1.2 device."
