In this booming era of the Industrial Revolution 4.0, the issue of teachers willingness to use information technology in teaching Arabic is often debated. The emergence of new technologies, such as augmented reality technology applied in the education system, has had a positive effect on teaching. However, there is still a lack of research in the context of teaching a foreign language. Therefore, this study discusses the readiness of teachers from the aspect of their knowledge towards the use of augmented reality technology in teaching Arabic in primary schools. In addition, this study uses a quantitative study in the form of a survey method involving a total of 36 Arabic language teachers who were used as respondents in this study. The use of a set of questionnaires as a research instrument is the basis for data collection to identify their level of knowledge readiness. The data from this study were processed using the Statistical Package for the Social Science version 26 (SPSS). The results of the study show that the level of readiness of teachers from the aspect of knowledge towards the use of augmented reality technology in the teaching of Arabic in Malaysia is at a moderate level. Therefore, it is hoped that this study will be used as a guide and benefit those responsible for ensuring that the process of teaching and learning Arabic based on augmented reality technology can be implemented in a meaningful way, thereby improving the performance of students in mastering the Arabic language.
