Studi ini mengajukan kesimpulan bahwa sebagaimana pesantren NU lain, Pesantren Musthafawiyah mengembangkan prinsip-prinsip <em>al-mu<span style="text-decoration: underline;">h</span>âfazhah ‘ala qadîm al-shâli<span style="text-decoration: underline;">h</span> wa al-akhzu bi al-jadîd al-ashlâ<span style="text-decoration: underline;">h</span>, tawâzun, ta‘âdul, </em>dan <em>tasâmu<span style="text-decoration: underline;">h</span> </em>dimana seluruh prinsip tersebut menjadi nilai-nilai dasar yang diterapkan dalam pembelajaran. Tentu saja, studi ini memperkuat kesimpulan sejumlah peneliti bahwa pesantren mengusung paham Islam moderat dan menolak radikalisme dalam beragama dan bernegara.<br /><br /><strong>Abstract: </strong><strong>Reaffirming <em>Nusantara Islam</em>: Nahdlatul Ulama and the Educational Philosophy of Pesantren<em> </em>Musthafawiyah.</strong> This study analyzes the educational philosophy of Pesantren Musthafawiyah, a theme that has not been properly studies by former researchers.
