Arabic Script Writing System

Timeline

1. c. 500–600Northern Arabian Peninsula · Syrian DesertThe Nabataean alphabet gradually evolved into the early Arabic script in northern Arabia and the Hejaz, with letter forms shifting from isolated to ligatured writing, laying the graphic foundation for large-scale written transmission in the Islamic era.
2. c. 610–632Mecca and Medina · HejazThe Quran was revealed orally in Arabic and early recorded in Arabic script on palm leaves, leather, and bone slips; the practice of written copying promoted the formation of letter joining, word separation, and basic spelling rules.
3. c. 650–656Medina · HejazThe third caliph Uthman oversaw the compilation of a unified Quranic codex and distributed copies to the regions; the standardized manuscript became an important model for Arabic script writing, promoting consistency in glyph forms and spelling.
4. c. 660–700Basra and Kufa · IraqTo eliminate reading ambiguity caused by homomorphic letters, scholars in Iraq introduced systems of vowel points and consonant diacritics, making Arabic writing more precise and legible, and spread with the Islamic conquests to newly conquered regions.
