The phenomenon of disintegration in Indonesia has been occurring since the political reforms that started in 1998 through the advent of radicalism and terrorism, eroding the national sense of identity and unity. This paper explores the national safeguarding concepts by emphasizing two research questions: (1) How do the social conflicts in Indonesia rooted in the religious perceptions threat the safety national buildings?, and (2) How are insights of national safeguarding nation approach from Haramain al-Juwayni's View of "Maqa?id Shari'ah" offer the way to resolve the national disintegration? This study takes the form of library research employing the content analysis from which various texts on Islamic nation buildings were examined. As a qualitative approach, this study focused on the analysis of themes of the purstanding Islamic influencers on "Usul Fiqih." Thematic analysis regarding misleading perceptions on Islamic rules on the nation buildings and approach to resolve nation disintegration were presented. Through this study, we discovered that Islam offers a concept for safeguarding the sovereignty and unity of a nation, one that has not yet been extensively explored by previous scholars, namely "maqa?id shari'ah" in the form of "?if? al-dawlah" (safeguarding a nation). There will hopefully be other comprehensive studies in future to bring forth other leading concepts for preserving national unity and integrity.
