François Déroche schreibt zum Fragment KFQ 51 (Déroche, The Abbasid Tradition, London 1992, S. 109): "56 / Six folios / First half oft he 10th century AD / 17.4 x 13.5 cm, with 5 lines to the page / Material Parchment; the verso is the hair side in all six cases / Text area 9 x 7.7 cm / Script Style D.Vb / Accession no. KFQ 51 / As is often the case, style D.Vb is associated here with the vertical format. This slender script retains the basic letter forms of group D, but the play on the varying thickness of the line, which is such a strong feature of the D.I manuscripts, has been deliberately abandoned: final nūn provides a particularly good illustration of this. Mashq was not used, perhaps because of the vertical elongation of the letters, and the upper strokes of ṭāʾ, ẓāʾ, kāf sometimes slant to the right before turning to the left. This can be seen on folio 5, verso, line 2, but its occurrence there may be explained by the lack of space. In a related example, cat.61, whose script is somewhat coarser, this practice was used regularly (see lines 2 and 4 of the verso). These elements, together with the format, suggest that the influence of NS.I was quite strong, and it is probable that the two scripts were in use at the same time. / The illumination of D.Vb manuscripts, and , more particularly, the frequent use of ornaments 4.A.I and 4.A.II to separate groups of five verses, which can be seen , for example, in cat.60 and 89, Istanbul, Topkapı Palace Library, MS.EH 34 (Karatay 1962, no 51), and Paris, Bibliothèque Nationale, MSS arab.368 and 373d (Déroche 1983, nos 174 and 176), suggests that there was , if not a proper school or scriptorium, at least a strong tradition among the calligraphers who used D.Vb. / These six folios formed part of three different quires. The text they contain – Sūrat al-qaṣaṣ (XXVIII), verses 33-35 (folio I), 72-77 (folios 2-5) and 79-80 (folio 6) – is written in dark brown ink. Red dots indicate the vocalization. The verses are punctuated by a 3.1.1 or 3.1.2 marker. Groups of five verses are marked by a 4.A.II illumination with the word khams (‘five’) written in gold on a green ground. A vignette in the margin of folio 1a indicates a subdivision of the text, while a short note on folio 6 recto shows that the manuscript was an endowment.”
