Rasm

Rasm (Arabic: رَسْم) is an Arabic writing script often used in the early centuries of Classical Arabic literature (7th century – early 11th century AD). Essentially it is the same as today's Arabic script except for the big difference that the Arabic diacritics are omitted. These diacritics include i'jam (إِعْجَام, ʾIʿjām), consonant pointing, and tashkil (تَشْكِيل, tashkīl), supplementary diacritics. The latter include the ḥarakāt (حَرَكَات) short vowel marks—singular: ḥarakah (حَرَكَة). As an example, in rasm, the five distinct letters ـبـ ـتـ ـثـ ـنـ ـيـ are indistinguishable because all the dots are omitted. Rasm is also known as Arabic skeleton script.

This article needs attention from an expert in Islam. The specific problem is: alleged uncited uncontextual claims about Classical Arabic on ornamental diacritics and the forms of the letter yāʾ. (October 2020)
