Arabic language learning is one of the main focuses in Islamic education in Indonesia, especially in religious institutions such as the West Java Islamic Da'wah Center (Pusdai). This is due to the difficulty in understanding the contents of the Qur'an, which is still experienced by many people as a result of their limited command of Arabic. This study aims to analyze the role of Arabic language learning at the West Java Islamic Da'wah Center (Pusdai) as a means of understanding the Qur'an. The research uses a descriptive method with a qualitative approach and field research. Data was collected through observation, interviews, and documentation, involving teachers (ustadz/halaqoh mentors) and program managers as the main sources of data. Based on the results of the study, the learning process includes the delivery of theory (nadzoriyah), practical application (tathbiq), and the development of language skills (maharat), namely listening, speaking, reading, and writing. Arabic language learning activities at Pusdai West Java play an important role in improving participants' ability to read, write, and understand Arabic. These activities not only deepen participants' understanding of Arabic language structure but also help them accurately comprehend the meaning of Quranic verses, avoid misreadings, and appreciate the beauty of the revealed language. Thus, Arabic language learning in halaqah at Pusdai West Java has proven to be an effective means of strengthening religious understanding, fostering spiritual awareness, and building a closer connection with the Quran.
