almulhida,
Classical Arabic (CA), also known as Qur'anic or Koranic Arabic, is the form of the Arabic language used in literary texts from Umayyad and Abbasid times (7th to 9th centuries). It is based on the Medieval dialects of Arab tribes. Modern Standard Arabic (MSA) is the direct descendant used today throughout the Arab World in writing and in formal speaking, for example, prepared speeches, some radio broadcasts, and non-entertaining content.[1] While the lexis and stylistics of Modern Standard Arabic are different from Classical Arabic, the morphology and syntax have remained basically unchanged (though MSA uses a subset of the syntactic structures available in CA).[2] The vernacular dialects, however, have changed more dramatically.[3] In the Arab world, little distinction is made between CA and MSA, and both are normally called al-Fuṣ-ḥā (الفصحى) in Arabic, meaning 'the clearly spoken one' or the 'language of eloquence'.
No, I'm trying to learn some QA
You can't just learn "some" QA, especially if you want to read the Quran in its own language. Habibi, you'll have to learn a
lot of fucking QA. Also,
No, I'm trying to learn some QA not because of some interest in culture. It's because I keep hearing Muslims giving the excuse since I don't understand the Quran, then I shouldn't be commenting about. And there is probably some truth to that.
No, there is no truth to that whatsoever. It's a red herring. You have dozens of translations available to you, you have Lane's Lexicon available to you, you actually understand the Quran better than almost ANY Arab who just picks it up and reads it without any external texts. You should only learn Arabic if you want to study the Quran in-depth, as in, actually become a scholar of the Quran. It's like learning Hebrew and Greek to read the Bible -- entirely pointless, unless you're a biblical scholar. And you really don't need to do that to see how stupid it is, and to show others how stupid it is.
If you want to learn Quranic Arabic regardless, your best bet is probably to enroll in a course at your local university.
