Classical Arabic and the Language of the Hijaz Before the Mission

Question:
Honorable Shaykh, he says: Is Classical Arabic the language of the Arabs in the Hijaz before the Mission? And is there a colloquial language in the Hijaz, Egypt, and the Levant?

Answer:
Classical Arabic was with the people of the Hijaz and the Tamim, and therefore the grammarians speak of the language of Tamim and the language of the people of the Hijaz. The language in which the Qur'an was revealed is mostly the language of the people of the Hijaz, the language of Quraysh, though it may have been revealed in some of the language of the Tamim. The Qur'an was revealed in Classical Arabic, which is found among the Arab tribes, whose dialects differ in it. The colloquial language did not emerge until after the blessed centuries, when the non-Arabs mixed with the Muslims in the Abbasid state, and errors occurred in the language. This is why the grammarians do not cite as evidence except poetry from the pre-Islamic age of ignorance or from the early period of Islam and the era of the Umayyads; this is what they use as proof.
As for what was from the era of the Abbasids, they do not use it as proof, because in that era the colloquial language and errors entered the language of the Arabs.
