François Déroche schreibt zum Fragment KFQ 33 (F. Déroche, The Abbasid Tradition, London 1992, S. 60): "13 / Single folio / Late 8th century AD or early 9th / Fragmentary (largest dimensions now 21x18.5cm), with more than 14 lines to the page / Material Parchment; the verso is the hair side / Text area Reduced to 18.1x18.5cm / Script Close to style C.Ib / Accession no. KFQ33 / Although the hand of this fragment lacks one feature of style C.Ib – the triangular endings of final nūn and lām – it resembles this style in other respects: the tripartite final nūn, the almost triangular initial and medial hāʾ (verso, line 5), and the peculiar form of final qāf, with its tail on the line below (verso, line 8). / The text - Sūrat Yūsuf (XII), verses 39-56, with a lacuna between verses 45 and 47 – is written in dark brown ink, with some diacritical strokes. Red dots indicate the vocalization. Clusters of three strokes (I.I.I) mark the end of every verse, and a red circle (I.A.I) indicates the end of a group of ten verses."
