The idea of realizing the ideal society in the light of the global sovereignty of the righteous constitutes one of the fundamental pillars of the political system of the Holy Quran. The present study aims to elucidate the Quranic foundations of the inheritance of the earth and to examine the role of the righteous servants (ʿibād ṣāliḥūn) and the oppressed (mustaḍʿafūn) in the realization of monotheistic civilization. Adopting a descriptive-analytical method, the research draws upon the exegesis of key verses, namely verse 33 of Sūrat al-Tawbah, verse 9 of Sūrat al-Ṣaff, verse 55 of Sūrat al-Nūr, verse 5 of Sūrat al-Qaṣaṣ, and particularly verse 105 of Sūrat al-Anbiyāʾ. The main research question is: What are the Quranic foundations of the tradition of inheriting the earth and the victory of the righteous, and how is the role of the righteous servants and the oppressed in realizing the ideal society and monotheistic civilization under the global sovereignty of the righteous to be explained? The findings indicate that the Holy Quran regards the inheritance of the earth not as an accidental or limited occurrence, but as a definitive tradition (sunnah) and an irrevocable divine promise that guarantees the righteous the good end of existence. According to these verses, the inheritance of the earth by the “righteous servants” is a general law within the order of creation, which will be actualized in this very material world and on a global scale. The word al-arḍ (“the earth”), bearing the definite article of generic denomination (lām al-jins), signifies the comprehensive sovereignty of the righteous over all political, social, economic, and cultural dimensions of the earth. The complete fulfillment of this divine promise marks the terminus of the struggle between truth and falsehood, reaching its culmination in the era of the appearance (ẓuhūr) of Imam al-Mahdi (may God hasten his blessed reappearance) and within the context of the return (rajʿah) of the divine saints. In this era, the righteous will be not merely the heirs of power, but the leaders and architects of monotheistic civilization, universal justice, and human felicity
