François Déroche schreibt zum Fragment KFQ 21 (Déroche,  The Abbasid Tradition, London 1992, S. 103): "50 / Two folios / End of the 9th century AD or first half of the 10th / 12.2 x 18.3 cm (folio I) and 12 x 19 cm, (folio 2), with 7 lines to the page / Material Parchment / Text area 5.7 x 12.3 cm / Script Perhaps style D.Va / Accession no. KFQ 21 / The text on these two folios, Sūrat al-anbiyāʾ (XXI), verses 6-16, runs consecutively, and the two folios must have been part of the first half of a quire, as the recto is the hair side in both cases. The text is written in black ink, with diacritical strokes; some of these are later additions, probably made when a later hand wrote over the letters. Red dots indicate the vocalization. The verses are not punctuated. A gold Kufic hāʾ marks the end of every fifth verse, while the end of every tenth verse is marked by an ornament, now damaged, which may have been of type 2.A.II.”
