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. kataba line 7



The curves of letters such as rāʾ, dāl, and wāw have been flattened.
e.g. Madr wa Rizm line 2

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.
