What do you say about someone who claimed that "Taha," "Alif, Lam, Mim," and "Nun" are Aramaic words, and that interpreting the Qur'an requires knowledge of the Aramaic language, citing Al-Tabari's interpretation of "Taha" as "O man" and what is mentioned in Sahih Al-Bukhari?

The statement that learning Aramaic is obligatory to understand the Quran is incorrect, for the Quran was revealed in a clear Arabic tongue. Whoever denies this has disbelieved in Allah Almighty. As for the words found therein that are said to be foreign, they are either words upon which languages converged, or they are a few foreign words that do not render the Quran anything other than clear Arabic, and they do not necessitate learning another language. Scholars have explained the meaning of these words said to be foreign in Arabic, so there is no need to learn other languages to understand them.
