Arabic is the source language of the Qur'an and hadith which is the main reference in Islamic da'wah activities. The mastery of Arabic by dai is an important factor in maintaining the accuracy of the meaning and quality of delivering religious messages to the community. However, the reality on the ground shows that not all dai have adequate Arabic language skills. This study aims to describe the urgency of mastery of Arabic for dai in the delivery of the Qur'an and hadith in Purwoasri Village, Pacitan. The research uses a qualitative descriptive approach with data collection techniques through observation, in-depth interviews, and documentation. The research subjects consist of dai and religious education figures. The results of the study show that the limited mastery of Arabic causes dependence on translation, the potential for misinterpretation, changes in meaning due to reading errors, and low understanding of the congregation. Therefore, mastery of the Arabic language, at least passively, is an urgent need for the dai to improve the quality of da'wah and maintain the purity of the meaning of the Qur'an and hadith in society.
