Classical Arabic

Classical Arabic is the specific seventh-century Central Arabian literary register in which the Quran was revealed and recorded, belonging to the Central Semitic branch of the Afroasiatic language family alongside Hebrew and Aramaic, and its grammar was formally codified shortly after Islam's spread by early Arab grammarians, most influentially Sibawayh in the eighth century, partly to preserve correct Quranic recitation as Islam expanded rapidly among non-Arabic-speaking converts across a vast new empire.

Classical Arabic differs meaningfully from Modern Standard Arabic, its direct descendant used today for formal writing and broadcast media, chiefly in certain grammatical constructions and a smaller, more archaic vocabulary set, though the two remain close enough that educated modern Arabic speakers can read the Quran directly rather than requiring a separate translation, a continuity most world religions' scriptures in their original languages do not offer contemporary readers. Pre-Islamic Classical Arabic poetry, transmitted orally before Islam and later collected in writing, provided some of the linguistic and literary foundation against which the Quran's own distinctive prose style was received and judged by its earliest audience.

The Quran's text was compiled into a single authoritative written recension under the third caliph Uthman around 650 CE, an effort traditionally understood as standardizing the text against several earlier variant collections and distributing authoritative copies to major cities of the expanding Islamic empire, with a small number of manuscripts, including one preserved in Tashkent and fragments elsewhere, traditionally associated with this early standardization effort, though their precise dating remains a subject of ongoing manuscript scholarship. Early Quranic manuscripts were written in a simple consonantal Arabic script without the vowel markings and dotting later added to distinguish otherwise identical consonant letters, and the gradual introduction of diacritical marks and vowel signs from the seventh century onward, driven partly by the practical need to guide correct recitation, tajwid, remains central to Quranic recitation training today, treated as inseparable from the text's proper transmission rather than a mere pronunciation guide, and Quranic recitation competitions and formal certification in tajwid remain a significant feature of contemporary Islamic religious education worldwide.
