Yawm al-Fasl, the “Day of Decision” of Sūrah An-Naba (78:17), is the appointed time of judgement when truth is separated from falsehood and every dispute is settled — the climax toward which the sūrah’s signs of creation point.

Overview

After rehearsing its signs of creation, Sūrah An-Naba names the appointed reckoning: “Indeed, the Day of Decision is an appointed time” (78:17). This يَوْمَ الْفَصْلِ (yawm al-fasl) is the day God has fixed to separate truth from falsehood and to judge between people in everything they disputed. It is announced by the Trumpet — “the Day the Trumpet is blown and you will come forth in crowds” (78:18) — and it sorts humanity toward the Gardens or toward the recompense of the transgressors.

Etymology and meaning

The word فَصْل (fasl) carries the sense of separating, distinguishing, and deciding — drawing a clear line between two things. The same root gives fāsil, a divider or partition, and the idea of a decisive, clarifying judgement (qawl fasl, a decisive word). So yawm al-fasl is at once the Day of Separation, when the truthful are set apart from the deniers, and the Day of Decision, when every contested matter is finally settled.

Significance

In Sūrah An-Naba the Day of Decision is the answer to the “great news” the deniers argue over. The sūrah first lays out ordered signs — the earth as a resting place, the mountains as pegs, the alternation of night and day, the seven heavens, and the blazing lamp — then declares that the God who set all this in order has fixed a day to set accounts right.

That it is “an appointed time” (mīqāt) underlines that judgement is neither random nor avoidable but scheduled. The repeated questioning of 77:14, “what can make you know what is the Day of Decision?”, marks it as a reality beyond full grasp, while 37:21 frames it as the very day the deniers refused to believe in — now arrived. Its outcome is decisive separation: the God-conscious to a place of triumph, the rejectors to the recompense of the transgressors.
