According to search-discovered classical Islamic scholarship, the Day of Judgement, known in Arabic as Yawm al-Qiyamah (The Day of Resurrection), is a fundamental and non-negotiable pillar of Islamic faith. It represents the absolute end of temporal existence, whereupon Allah will resurrect all of humanity for a final, perfect reckoning. Classical exegetes like Ibn Kathir, synthesizing over 120 Quranic verses and numerous authentic hadith, explain this as a literal day of cataclysmic events, including the leveling of mountains and splitting of the sky, followed by a bodily resurrection. Al-Qurtubi further clarifies that this day, also called Yawm ad-Din (The Day of Judgement), is when every soul will be held accountable for its deeds, weighed upon the Mizan (the Scales), and face the consequences of its life on earth. Imam al-Ghazali emphasizes that the certainty of this Day is meant to shape a believer's consciousness, instilling a profound sense of purpose, morality, and urgency in spiritual preparation. This synthesis across scripture and scholarship establishes Judgement Day not merely as a future event, but as the ultimate validation of divine justice and the defining reality that gives meaning to human existence.
