Arabic language instruction in *madrasahs* (Islamic schools) continues to face various challenges, most notably low student engagement, which negatively impacts learning outcomes. This study aims to analyze the effect of implementing the *Kullu Insan Huna Mudarrisun* method on the Arabic language learning outcomes of eleventh-grade students at MAN 2 Jambi City, specifically regarding the topics of *Jumlah Ismiyah* (nominal sentences) and *Jumlah Fi'liyah* (verbal sentences). The study employs a quantitative approach with a one-group pretest-posttest design. The sample consists of 36 students, selected using a purposive sampling technique. Data were collected through learning achievement tests administered before and after the intervention. Data analysis was conducted using the Shapiro-Wilk normality test and the Wilcoxon Signed-Rank Test. The results indicate a significance value of 0.026 (p < 0.05) in the Wilcoxon test, demonstrating a significant effect of the *Kullu Insan Huna Mudarrisun* method on students' Arabic language learning outcomes. Twenty-nine students showed an improvement in their scores following the intervention, while seven students experienced a decline. These findings suggest that the *Kullu Insan Huna Mudarrisun* method is effective in enhancing students' understanding, engagement, and participation in Arabic language learning. Consequently, this method can serve as an alternative instructional strategy that supports active, learner-centered education.
