This chapter attempts to accurately investigate the conception to take a benefit as an ethical foundation of character education, known as the concept of istifādah. This refers to the insightful value of al-Zarnūjī's Ta'lim al-Muta'allim, containing fundamental principles in the context of education, which has been used by the Islamic boarding school Pesantren in Indonesia. This research is employed through literature study using descriptive analysis. The findings reveal that there four core stages to examine istifādah for personal development in Islamic education context. Those are integrating Hikmah (wisdom) based moral quality for personal development, sustaining continuous discipline, nurturing effective time management, and empowering strategic effort with experiential foundations. Moreover, this study is supposed to give the contribution mainly in supplementing the theoretical basis on personality development in Islamic education context.
