Al-Hassan Ibn Ahmad Ibn Abd Al-Ghaffar Al-Farsi Al-Fasawi Abu Abu Ali is a scholar of Arabic and Persian, and he is prominent in the rules of the Arabic and Persian languages, However, until you do not study the high place among the scholars of the Arab sciences in the form that it deserves. This is while senior scholars emphasized Abu Ali’s high position, and even “Sapphire Hamwi” in the dictionary of literature considered him one of the elites of his time, and “Abu Ali Abdi” considered him more capable in grammar than Sibawayh. The purpose of this article is to present Abu Ali Al-Farsi as one of the main geniuses and theorists in Arabic grammar and to learn more about his distinctive grammatical views by relying on the descriptive-analytical method. The results showed that Abu Ali al-Farsi had a different style than other scholars of grammar, and one of his most prominent features is citing the Qur’an and Qur’anic readings in this regard. In any case, we see that some described him as a follower of the Baghdad madhhab in grammar, while others described him as a follower of the Basra madhhab. The basis of Abi Ali's grammatical views are the seven readings, and he does not depart from this religion.
