The Quran and the Silence Between Oaths: How 'Lā Uqsimu' Reveals the Rhetoric of Divine Negation

The Oath That Denies Itself

There is a phrase in the Quran that has perplexed, fascinated, and humbled Arabic linguists for over fourteen centuries. It appears at the opening of some of the most powerful passages in the entire scripture, and yet it seems, at first glance, to contradict itself. The phrase is lā uqsimu — literally, "I do not swear."

And yet, every time this phrase appears, what follows is unmistakably an oath. God invokes the Day of Resurrection, the self-reproaching soul, the twilight sky, the stars in their positions — and prefaces these invocations with what appears to be a denial of the very act of swearing. Consider Surah al-Qiyamah: "Lā uqsimu bi-yawm al-qiyāmah, wa lā uqsimu bi-l-nafs al-lawwāmah" — "I do not swear by the Day of Resurrection, nor do I swear by the self-reproaching soul" (75:1-2). And yet the entire surah proceeds as if the oath has been made, as if the negation was itself the most emphatic form of affirmation.

This is not a scribal error. It is not a grammatical accident. It is one of the most remarkable rhetorical strategies in the Arabic language, and understanding it takes us deep into the Quran's unique relationship with speech, meaning, and the inadequacy of human categories to contain the divine voice.

The Grammarians' Dilemma

Classical Arabic grammarians were sharply divided over lā uqsimu. The great Basran and Kufan schools of grammar — the two major traditions that shaped Arabic linguistic thought — offered competing interpretations, and their disagreements reveal just how much the Quran pushed the boundaries of the language it chose to inhabit.

One school held that the lā here is what grammarians call lā zā'idah — an "extra" or "expletive" particle. In this reading, the lā carries no semantic weight of negation. It is ornamental, emphatic, a kind of rhetorical throat-clearing before the solemnity of what follows. The meaning would simply be: "I swear by the Day of Resurrection." This interpretation, favored by scholars like al-Akhfash and later by al-Zamakhshari in certain passages of al-Kashshāf, treats the particle as a feature of elevated Arabic style — a mark of grandeur, not denial.

But another tradition, championed by scholars like Abu Ubayda and explored with subtlety by al-Razi in his Mafātīh al-Ghayb, insisted that the lā is genuinely negative — and that this is precisely the point. In this reading, God is saying: "I need not swear by these things. The truth I am about to declare is so self-evident, so overwhelming, that even swearing by the most magnificent phenomena in creation would be beneath the statement I am making." The negation of the oath becomes an assertion more forceful than the oath itself.

This second reading is extraordinary. It suggests that the Quran is doing something that no human poet or orator would dare: it is transcending its own rhetorical apparatus. It sets up the structure of an oath — the most solemn and binding form of speech in pre-Islamic Arabian culture — and then declares the structure insufficient for the weight of what it carries.

Where It Appears — and Why It Matters

The phrase lā uqsimu appears in several surahs, and in every case, the subject matter is of the utmost gravity. In Surah al-Qiyamah (75:1-2), it precedes a meditation on resurrection and the soul's inner accountability. In Surah al-Wāqi'ah (56:75-76), it is followed by: "Fa lā uqsimu bi-mawāqi' al-nujūm, wa innahu la-qasamun law ta'lamūna 'aẓīm" — "I do swear by the positions of the stars — and indeed it is an oath, if you only knew, most great." Here the Quran does something breathtaking: it negates the oath, makes the oath, and then comments on the magnitude of the oath, all in the span of two verses. The reader — the listener — is pulled through three layers of rhetorical awareness simultaneously.

In Surah al-Balad (90:1), "Lā uqsimu bi-hādhā al-balad" — "I do not swear by this city" — the subject is Makkah, and the Prophet's sacred bond with it. The negation here has been read by some scholars as a lament: I will not swear by this city, because its people have violated its sanctity by persecuting the one who was born in it. The grammar becomes theology. The particle becomes elegy.

In Surah al-Takwīr (81:15-18), the phrase introduces a sequence of cosmic oaths — the retreating stars, the falling night, the breathing dawn — before arriving at the declaration that the Quran is indeed the word of a noble messenger. The negation at the start pulls the listener into attentiveness, the way a sudden silence in a crowded room commands more attention than a shout.

The Rhetoric of the Unsayable

What lā uqsimu reveals is something fundamental about the Quran's philosophy of language. The Quran does not merely use Arabic; it interrogates Arabic. It takes the tools of human expression — oaths, narratives, parables, imperatives — and bends them toward a meaning that always exceeds the container. The divine voice, as it enters human language, leaves traces of its own untranslatability. The lā in lā uqsimu is one such trace.

This is why translation is so fraught here. English renderings oscillate between "I swear" and "I do not swear" and "Nay, I swear" — each one capturing a fragment and losing the rest. The Arabic holds all three meanings in suspension, and the reader is meant to feel that suspension, to dwell in the productive discomfort of a phrase that says yes and no at the same time, not because it is confused, but because it is pointing beyond the binary of affirmation and denial toward a mode of speech that belongs to God alone.

The medieval rhetorician al-Jurjānī, in his landmark Dalā'il al-I'jāz, argued that the miracle of the Quran lies not in its individual words but in the naẓm — the arrangement, the syntax, the way meaning arises from the spaces between words as much as from the words themselves. Lā uqsimu is perhaps the purest illustration of this principle. The meaning is not in lā alone, nor in uqsimu alone, but in the electric space between a negation and an oath, a silence and a declaration, a refusal to speak and an act of speech so powerful it anchors entire surahs.

What the Silence Teaches

For the reader of the Quran — whether a student of Arabic, a seeker of faith, or a scholar of rhetoric — lā uqsimu offers a lasting lesson. It teaches that the most powerful statements are sometimes those that begin by questioning their own capacity to say what needs to be said. It teaches that humility before meaning is not weakness but the highest form of eloquence. And it teaches that the Quran's Arabic is not simply a vehicle for a message delivered from above; it is itself a field of meaning, a landscape where every particle, every negation, every breath between syllables is doing theological work.

When God says lā uqsimu, He is not confused about whether He is swearing. He is showing us that human language, even at its most exalted, shivers when asked to carry the weight of the divine. And the shiver — the lā that should not be there and yet must be there — is itself a sign, for those who listen not just with their ears but with the silence that comes before understanding.
