The Quran contains approximately forty passages in which God swears an oath. In some, He swears by the sun. In others, by the stars, the wind, the fig, the olive, the pen. Each oath is calibrated to the subject that follows -- a cosmic exhibit presented before the verdict is read. But nowhere in the Quran is the oath more layered, more rhythmically compressed, or more philosophically demanding than in the opening five verses of Surah Al-Fajr.
"By the daybreak" 89:1. The Arabic is wal-fajr -- a single word that carries the weight of the entire surah's thesis. The dawn is not merely a time. It is a transition. It is the exact moment when darkness concedes to light, when the night's dominion ends and visibility returns. God begins by pointing at the hinge between blindness and sight, between ignorance and clarity. Everything that follows in this surah -- the collapsed empires, the exposed psychology, the final judgment, the invitation to paradise -- is framed as a dawn. A revelation. A moment when what was hidden becomes visible.
"And ten nights" 89:2. The scholars have debated which ten nights these are for fourteen centuries. The majority opinion, grounded in the commentary of Ibn Abbas, holds that these are the first ten nights of Dhul Hijjah -- the most sacred days in the Islamic calendar, the days of pilgrimage, the days in which, according to prophetic tradition, no righteous deed is more beloved to God. Others argue they are the last ten nights of Ramadan, which contain Laylat al-Qadr, the Night of Power. What is not debated is their function in the oath: they are not ordinary nights. They are nights charged with spiritual density, nights when the boundary between heaven and earth is thinner than usual, nights when history's most consequential acts of worship take place.
"And the even and the odd" 89:3. Here the oath moves from the specific to the mathematical. The even and the odd -- ash-shaf'i wal-watr -- encompass all of creation. Every number is either even or odd. Every pair has a counterpart; every singular thing stands alone. The scholars read this as a reference to the fundamental duality and unity woven into existence: creation comes in pairs, but God is One. The watr -- the Odd, the Singular, the Unique -- is one of God's own names. He swears by the structure of mathematics itself, the binary architecture that undergirds every atom and every galaxy, and buries within that oath a reminder: at the bottom of all duality, there is a unity. At the foundation of every pair, there is a One.
"And the night as it recedes" 89:4. The final element of the oath is motion. Not the night itself, but the night in the act of departing. The Arabic yas-ri carries the sense of travelling, journeying, moving through. The night does not simply end -- it travels away, yielding the stage to the dawn that opened the oath. The structure is circular: dawn, sacred nights, the fabric of existence, and then the night pulling back like a curtain. The oath begins with light arriving and ends with darkness departing. Between them, all of time and all of number are summoned as witnesses.
And then the question -- the only question that matters: "Is there in this an oath for a rational person?" 89:5. The Arabic dhi hijr means one who possesses intellect, discernment, the faculty of reason. God is not asking whether the oath is impressive. He is asking whether a thinking person can witness the dawn, contemplate the sacred nights, observe the even and the odd, and watch the night recede -- and still fail to recognise that these phenomena are testimony. That the universe is not accidental. That the patterns encoded in time and number are evidence of a Designer who, having arranged the cosmos with this degree of precision, might also have arranged human history with purpose, and might also have arranged a final reckoning with justice.
The question is rhetorical, but its implications are not. The rational person -- dhi hijr -- is exactly the person the rest of the surah will address. The empires that fell were not led by irrational madmen. They were led by engineers, architects, military strategists, builders of pillared cities and rock-carved civilisations. They had intellect. What they lacked was the willingness to let that intellect lead them to its logical conclusion: that the God who built the dawn also built the reckoning.
