The Quran does not begin its final Juz with a declaration. It begins with a question. "What are they asking one another about?" 78:1. The Arabic amma yatasa'alun carries the texture of hushed, anxious inquiry — people interrogating each other in undertones, seeking reassurance that the thing they have been told is not real. And then the answer, delivered in two tight verses that function like a prosecutor naming the charge: "About the Great Event. About which they disagree" 78:2-3.
The Great Event — an-naba' al-azim — is the resurrection. The Day of Judgment. The accounting. The return. This is the subject the Meccans could not stop circling and could not bring themselves to accept. Their entire civilisational architecture was built on the assumption that death was final. Their poetry mourned the dead as gone. Their economics assumed a single lifetime of accumulation. Their morality, such as it was, operated within the boundaries of earthly consequence. And now a man stood among them — Muhammad, peace be upon him — telling them that every buried body would rise, every hidden deed would be displayed, and every soul would stand before a Judge who had been watching all along.
They disagreed. Not casually — the Arabic mukhtalifun suggests genuine, unresolved disputation. Some denied it outright. Some were unsure. Some suspected it might be true but found the implications unbearable. The disagreement itself was the problem. On a matter of this magnitude — whether death is the end or merely the intermission — uncertainty is not a neutral position. If the resurrection is real, then every decision you make in this life carries eternal weight. If it is not, then nothing ultimately matters beyond the grave. There is no middle ground. The Meccans were trying to occupy a middle ground that did not exist, and the Quran's opening question exposes the absurdity of that position.
Then comes the doubled warning, delivered with the force of a judge who has heard enough evasion: "Surely, they will find out. Most certainly, they will find out" 78:4-5. The repetition is not rhetorical decoration. It is intensification. The first kalla — surely — is a correction, a rebuke to the disagreement itself. You think this is debatable? It is not. The second thumma kalla — most certainly — elevates the rebuke to the level of absolute divine guarantee. The Great Event is not a hypothesis to be argued in Meccan salons. It is an appointment. And when it arrives, the disagreement will be settled — not by argument, but by experience.
What makes this opening remarkable is what it reveals about God's rhetorical strategy at the threshold of the Quran's final section. The thirtieth Juz — Juz Amma — is the section most Muslims memorise first, the section children learn before any other, the section recited most frequently in daily prayers. And God chose to open it not with a statement of power or a description of paradise, but with a question about the one thing humanity finds hardest to believe. The entire final act of the Quran is framed as an answer to the anxiety that death might not be the end. Everything that follows in Surahs 78 through 114 — every description of heaven and hell, every cosmic upheaval, every angel and trumpet — is an elaboration of the Great Event that the Meccans whispered about and could not resolve. The Quran resolves it for them. In forty verses. Starting now.
