This document features a chancery script. The script is highly cursive. Letters are highly compressed and often written with a notable diagonal slant which contradicts the baseline, which is perfectly flat and straight.

Words are crowded across the line, occasionally alleviated using madd (letter lengthening).
e.g. kitāb line 2


The curves of letters such as rāʾ, nūn, and lām have been flattened.
e.g. Billawr line 10

 

Some of these features, particularly flattened curves and diagonal strokes, are also found in contemporary Pahlavi documents. It is possible that bilingual Arabic-Pahlavi administrators imported elements of the ductus of Pahlavi script into their Arabic writing.
