Arabic letters, mostly without diacritical points

Evidence

"The fact that the text written in Arabic letters is found on a “recycled” chancery document may be due to pure coincidence, but may also reflect the activities of a scribe whose proficiency in writing Arabic was related to the access he had to such used pieces of official documents."

Remarks

Sample T-S NS. 322.19 contains Arabic text in Arabic letters but lacks diacritical points (p. 28). The reuse of official chancery paper for magical recipes suggests a high degree of scribal access to official waste materials in medieval Cairo.
