The Borders of the Islamic State in the Noble Quran: An Analysis of Geographical and Doctrinal Duality in the Political System of Islam

Explaining the Quranic foundations of the borders of the Islamic state, as a fundamental question in Islamic political thought, holds significant theoretical and practical importance. This issue becomes doubly necessary when confronting the dominant paradigm of the international system based on nation-states with territorial sovereignty, as well as in response to extremist intellectual currents that either completely disregard borders or absolutize nationalism. Focusing on the Noble Quran as the foundational text of Islam, this research seeks—through an inferential method—to present a comprehensive model for analyzing the nature of these borders. The main question is: Do the borders of the Islamic state in the Quran have a geographical nature (arising from human agreements and social contracts) or a doctrinal nature (arising from the division between faith and disbelief)? And how do these two levels interact with one another? To answer this question, the theoretical framework of distinguishing between the “institution of the state” and the “office of leadership” is employed. This distinction serves as the key to resolving the apparent paradox between the universalism of the religion of Islam and the necessity of administering societies within specific political units. The research proceeds using the method of thematic interpretation of the Quran, relying on inferential reasoning and the method of implication—particularly the signification by correspondence (dilālat al-muṭābaqa) and the signification by implication (dilālat al-iltizām) of verses. The analysis centers on verses that directly or indirectly address governmental relations, migration, jihad, defense, and interactions with other societies (such as those in Surahs al-Tawbah,
al-Mumtaḥanah, al-Ḥujurāt, and Āl ʿImrān). To complete the analysis, evidence is also drawn from the Prophetic practice and jurisprudential-theological perspectives. The Noble Quran recognizes the existence of distinct socio-political units. Verses that command reconciliation between “two groups of believers” (al-Ḥujurāt: 9) or establish distinctions in external relations between belligerent and non-belligerent disbelievers (al-Mumtaḥanah:
8–9) confirm this political realism. The establishment of the Prophet’s government in Medina with a defined territory, along with his correspondence with rulers of other regions, provides a concrete example of this level of border delineation, which ensures order, security, and the implementation of rulings within a territory under authority. At a deeper and more foundational level, the Quran draws the primary boundary on the basis of “faith” and “disbelief.” Islam rejects any superiority based on race, ethnicity, or language
(al-Ḥujurāt: 13) and addresses all of humanity (al-Aʿrāf: 158), presenting a global and trans-border invitation. The noble verse “Say, ‘If your fathers… are dearer to you than Allah and His Messenger…’” (al-Tawbah: 24) clearly prioritizes doctrinal and jihad-related values over any spatial or kinship attachments. This level shapes identity and provides overarching direction for the Islamic Ummah. To resolve the apparent conflict between the above findings, the present research proposes a heuristic model: the intrinsic distinction between the “Islamic state” and “Islamic leadership.” The Islamic state is a terrestrial political institution bound by geographical borders, formed on the basis of allegiance (bayʿa), social contract, and practical extension of authority (basṭ al-yad), and it pursues executive, defensive, judicial, and economic functions within a defined territory. In contrast, Islamic leadership is a religious and guiding office with a trans-border and doctrinal nature. The leader (Prophet, Imam, or qualified jurist) is considered the leader of all believers in every part of the world and bears responsibility for the overall religious and political guidance of the entire Ummah, without being confined to specific borders. In this model, the Islamic state is responsible for providing internal order and security, preserving territorial integrity, and engaging in legal interactions with other states based on agreements. Islamic leadership, on the other hand, is responsible for the unity of the Ummah’s overarching orientation, intellectual guidance, and providing policy direction on comprehensive issues. This separation enables the coexistence of multiple independent Islamic states while preserving doctrinal connection and adherence to a shared intellectual system under unified leadership. Jurisprudential concepts such as Dār al-Islām, Dār
al-ʿAhd, and Dār al-Ḥarb, as well as rulings related to defensive jihad, presuppose the existence of geographical borders in practice. At the same time, the continued authority and leadership of the infallible Imams (peace be upon them) and jurists for Shiites outside the scope of political sovereignty testifies to the trans-border nature of the office of leadership. The Prophetic practice also continued the global invitation even while establishing the state in Medina. The research concludes that, from the Quranic perspective, the borders of the Islamic state possess two interconnected yet distinct levels: an operational-geographical level pertaining to the institution of the state and the necessities of governance in a plural world, and an identity-forming-doctrinal level pertaining to the Ummah and Islamic leadership, which operates beyond geography. Islam rejects ethnic or racial nationalism but accepts the formation of a state within geographical borders as a rational and practical reality. By presenting a two-level model and conceptually distinguishing between “state” and “leadership,” this research takes a step toward formulating an Islamic theory of borders that draws on political realism while upholding the universalist ideal of Islam. This framework not only addresses the current challenges facing the Muslim world in interacting with the international system but can also serve as a basis for unified action and   
convergence among Islamic states while respecting their national sovereignty. The full realization of a single global Islamic state remains the ultimate ideal on the horizon of
the appearance of the Universal Reformer, the Twelfth Imam (may God hasten his reappearance), but the present model elucidates a practical strategy for managing the period of occultation.
