This article aims to describe the role of P2MB students in an effort to increase student enthusiasm and discipline through methods targhib wa tarhib in learning the Qur'an. The method used in this research is a case study method with a qualitative approach. Research data were collected through observation and interview techniques. Observations are made by observing the learning process using the method targhib wa tarhib, and interviews were conducted by asking a number of questions to relevant sources such as teachers, and a number of students at Madrasah Nurul Iman. Based on the findings, it can be seen that the method targhib wa tarhib in Madrasah Diniyah Nurul Iman is implemented through learning the Al-Qur'an Al-Qari'ah letter. In learning, students as teachers explain about the rewards of good deeds and bad deeds in the afterlife. In addition, students (teachers) also discuss the contents of Q.S. Al-Qari'ah through media teaching question sheets, giving reward in the form of prizes for students who answered and punishment in the form of re-explaining for students who do not pay attention. Furthermore, based on the results of observations and interviews, it can be concluded that P2MB students act as innovators, motivators, and mediators in enhancing a positive, fun, enthusiastic and disciplined learning atmosphere through the targhib of tarhib on Al-Qur'an learning at Madrasah Diniyah Nurul Iman.
