Quranic Oaths: Structure and Meaning

Quranic Oaths: Structure and Meaning

Allah swears oaths throughout the Quran by various aspects of His creation and, in some instances, by Himself. These oaths (qasam, plural: aqsam) are a distinct literary and rhetorical feature of Quranic discourse, and understanding their structure and significance reveals deep dimensions of Quranic meaning that simple reading might overlook.

Types of Oaths in the Quran

Oaths by Creation

The majority of Quranic oaths are sworn by created entities: the sun (wa al-shamsi), the moon, the dawn, the night, the day, the wind, the fig, the olive, the city of Makkah, and the human soul itself. Allah swearing by His creation is not analogous to human oaths, because the Quran itself establishes that only Allah has the right to swear by Allah or by His creation. For humans to swear by creation is prohibited (the Prophet said: "Whoever swears, let him swear by Allah or remain silent"). When Allah swears by creation, He is honoring that creation and directing attention to it as a sign (aya) pointing to His power and wisdom.

Oaths by Time

Several surahs open with an oath by time or a portion of it. The most famous is wa al-asr (By time — Surah al-Asr: 1), and others include wa al-layl (By the night), wa al-fajr (By the dawn), and wa al-duha (By the morning light). These oaths by time direct the listener to reflect on how time is used, wasted, or invested — reinforcing the content of the surah that follows.

Structure of the Oath

An Arabic oath consists of two essential parts: the oath itself (al-qasam) and its response (jawab al-qasam). The oath introduces the object of the oath with the particle waw (و), qaf (ق-), or ta (ت-). The response to the oath is the claim being affirmed.

In Surah al-Asr, the oath is wa al-asr (By time) and the response is inna al-insaana la-fee khusr (Indeed, mankind is in loss). The oath lends weight and gravity to the response — it is as if Allah is saying: time itself bears witness to this truth. In Surah al-Shams, eleven consecutive oaths culminate in the response: "He has succeeded who purifies it [the soul], and he has failed who corrupts it." The accumulation of oaths emphasizes the profundity and certainty of this conclusion.

Examples: Surah al-Fajr

Surah al-Fajr opens with four oaths: by the dawn, by ten nights, by the even and the odd, and by the night as it passes. Scholars have discussed the precise references of these oaths at length. The ten nights are identified by many mufassirun as the first ten nights of Dhul Hijjah — the holiest days of the year. The even and the odd encompass all that Allah created, since everything is either paired or singular. The response to these oaths comes later in the surah: a reminder of Allah's punishment of nations that transgressed — 'Ad, Thamud, and Pharaoh — followed by the comfort given to the righteous soul (al-nafs al-mutma'innah) to return to its Lord in peace.

Examples: Surah al-Shams

Surah al-Shams contains the most oaths in a single surah: eleven. By the sun, by the moon, by the day, by the night, by the sky, by the earth, by the soul — each oath builds upon the last. The response affirms that the soul has been endowed with both its sinfulness and its righteousness, and that success belongs to the one who purifies it. This extended oath sequence communicates the enormous gravity of the human choice between purification and corruption.

Rhetorical Significance

The aqsam al-Quran (Quranic oaths) serve multiple rhetorical purposes: they arrest the listener's attention, they establish the gravity of the following statement, they point to the magnificence of creation as evidence of the Creator, and they demonstrate the Quran's unique literary register. Ibn al-Qayyim al-Jawziyya dedicated an entire work to this topic — al-Tibyan fi Aqsam al-Quran — analyzing each oath in detail, showing how the object sworn by always relates meaningfully to the response that follows.
