According to search-discovered classical Islamic scholarship, the concept of Al-Mizan (الميزان, The Balance) is a profound and multi-faceted principle of divine justice that permeates the Quran. Classical commentators like Ibn Kathir and Al-Qurtubi explain that Al-Mizan manifests in three distinct yet interconnected domains. Firstly, it is the cosmic equilibrium and perfect order established by Allah in the heavens and the earth (Quran 55:7), a universal system built on justice. Secondly, it represents the ethical and moral balance that humanity is commanded to uphold, particularly through fairness and equity (qist) in all social and economic dealings (Quran 57:25). Finally, and most centrally in Islamic eschatology, Al-Mizan is the real, tangible Scale of Justice that will be established on the Day of Judgment to weigh the deeds of every soul with absolute precision (Quran 21:47). The linguistic analysis by scholars like Al-Tabari confirms the root meaning of 'weighing', which the Quran applies consistently to this life's responsibilities and the Hereafter's accountability, thus establishing a unified framework where worldly justice is a direct preparation for the ultimate divine reckoning.
