If you can read the Quran fluently, learning Arabic for comprehension depends on factors like dedication, study methods, and prior exposure. Since Quranic Arabic has a classical structure, mastering Modern Standard Arabic (MSA) or conversational Arabic may take 6 months to 2 years with consistent effort. Understanding grammar (Nahw), vocabulary, and sentence structure is essential. Immersing in Arabic through books, courses, and conversations accelerates learning. With daily practice, guided lessons, and exposure to native speakers, achieving fluency in Arabic and Quranic knowledge becomes faster and more effective.
