This study aims to elucidate the key concept of “holding fast to God” (iʿtiṣām bi-llāh) and its role as a practical strategy within the paradigms of Islamic governance. Despite the Qur’an’s repeated emphasis on this principle, its position within contemporary governance discourses has remained relatively overlooked. Employing a descriptive–analytical method and drawing on authentic Qur’anic, exegetical, and narrative sources, this research explores the dimensions and implications of this concept. The findings indicate a profound convergence between the two Islamic schools (Sunni and Shia) regarding both the necessity and the proper manner of adhering to God. Moreover, neglect of this divine strategy stems from factors such as lack of faith and knowledge of God, mistrust toward Him, obstinacy, excessive sensualism and rationalism, and reliance upon others. The most significant fruits of iʿtiṣām in the sphere of governance include the encompassing mercy of God, realization of beneficence (iḥsān), enjoyment of God’s constant companionship, protection from apostasy and deviation, and assurance of guidance toward the straight path. These outcomes elevate iʿtiṣām to a foundational principle ensuring stability and effectiveness within the Islamic political system.
