Is the division of Arabs into "Aribah" (indigenous Arabs) and "Musta'ribah" (Arabized Arabs) correct? Does it contradict the Qur'an? And did it originate from the Jews?

Arab historians and chroniclers have divided Arabs into three categories:

1. The Extinct Arabs : Such as the peoples of 'Ad and Thamud. They were called so due to their antiquity and their demise before Islam. 2. The Pure Arabs: These are the Qahtanis, descendants of Qahtan ibn 'Abir. 3. The Arabized Arabs (the 'Adnanis): These are the descendants of Isma'il (peace be upon him). They learned Arabic from Jurhum, and thus their lineage became Arab.

This division is agreed upon in books of history and genealogy, and it does not contradict the Qur'an. Furthermore, it is unlikely to have been taken from the People of the Book, as ancient historical texts mention this division, and because the Torah does not mention the extinct Arabs; rather, Jews deny their existence. Dr. Jawad Ali affirms that this division is purely Arab, originating from the distinction between the Arabs who perished and the Arabs who remained.
