''Rasm'' ( ar, 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 ''

are indistinguishable because all the dots are omitted. ''Rasm'' is also known as Arabic skeleton script.
History

In the early Arabic manuscripts that survive today (physical manuscripts dated 7th and 8th centuries AD), one finds dots but "putting dots was in no case compulsory".
["What Are Those Few Dots for? Thoughts on the Orthography of the Qurra Papyri (709–710), the Khurasan Parchments (755–777) and the Inscription of the Jerusalem Dome of the Rock (692)"](_blank)
by Andreas Kaplony, year 2008 in journal ''Arabica'' volume 55 pages 91–101. The very earliest manuscripts have some consonantal diacritics, though use them only sparingly. Signs indicating short vowels and the hamzah are largely absent from Arabic orthography until the second/eighth century. One might assume that scribes would write these few diacritics in the most textually ambiguous places of the rasm, so as to make the Arabic text easier to read. However, many scholars have noticed that this is not the case. By focusing on the few diacritics that do appear in early manuscripts, Adam Bursi "situates early Qurʾān manuscripts within the context of other Arabic documents of the first/seventh century that exhibit similarly infrequent diacritics. Shared patterns in the usages of diacritics indicate that early Qurʾān manuscripts were produced by scribes relying upon very similar orthographic traditions to those that produced Arabic papyri and inscriptions of the first/seventh century." He concludes that Quranic scribes "neither
'left out' diacritics to leave the text open, nor 'added' more to clarify it, but in most cases simply wrote diacritics where they were accustomed to writing them by habit or convention."
''Rasm'' means 'drawing', 'outline', or 'pattern' in Arabic. When speaking of the
