The core of Arabic grammar is introduced: words are classified into three categories: Ism, Fi'l, and Harf. Harf is defined as a word that makes no sense on its own. Fi'l (verb) is defined as a word stuck in time (past, present, or future tense). Ism is then defined as a person, place, thing, idea, adjective, adverb, and more.

The instructor addresses confusion regarding 'ing' words in English, explaining how they can function as a Fi'l (verb) in certain contexts (e.g., 'he is cooking') and as an Ism (idea) in others (e.g., 'he loves cooking'). He provides a test: adding 'the act of' to determine if an 'ing' word is functioning as an Ism.

The instructor introduces the two test subjects for the course and explains the interactive teaching methodology. He emphasizes the importance of focus, energy, and a positive attitude for learning the language of the Quran. He also introduces the teacher's assistant, Jawad, who will moderate comments and questions.

The instructor outlines the expectations for the 10-day course, stressing complete focus on the material and avoiding distractions from other resources. He advises against taking notes until instructed, promoting active listening and participation. He introduces the online study packet and encourages students to read two pages of Quran daily to improve reading fluency.

The lesson begins by explaining the three types of Arabic: street Arabic (colloquial), Fusha (modern standard Arabic), and the language of the ancient Arabs (Lisan al-Arab), which is the language of the Quran. He differentiates between them using English examples like the evolving meaning of 'cool' and 'hot', and contrasts the modern Arabic meaning of 'ist'amara' (colonization) with its Quranic meaning (to build or develop).

The lesson transitions to the three grammatical states of an Ism: Rafa, Nasb, and Jarr. Rafa is introduced as the 'doer' of an action (Fi'l), Nasb as the 'details about the Fi'l' answering questions like 'what, where, when, how,' and Jarr as any Ism that comes after a preposition or an implicit possessive 'of'.

The class learns a crucial shortcut for identifying the state of an Ism in Arabic by its vowel sound endings: 'oo' or 'oon' for Rafa, 'a' or 'an' for Nasb, and 'e' or 'in' for Jarr. The instructor guides students through practice with Arabic words from the Quran, reinforcing these phonetic rules despite initial struggles.

The instructor concludes the first day, emphasizing the progress made and the importance of continued effort. He reminds students to download the study packet for the next session and re-affirms his commitment to patiently guide them through the learning process, fostering a positive and encouraging environment.
