Swearing by Other than Allah: What Do Authentic Sources Say?

Oaths and truthful speech · Authentic hadith, Qur’anic discipline and careful correction without judging people

Authentic hadith prohibit swearing an oath by anyone or anything other than اللّٰه (ALLAH). If an oath is genuinely needed, a Muslim should swear by اللّٰه (ALLAH) truthfully or remain silent. The warning is serious because an oath carries deliberate weight and veneration. Yet an oath is not the same as an ordinary promise, a passing idiom, a quotation or the evidence a witness gives. Those differences must be understood before anyone discusses a real person.

An oath is not just another emphatic sentence

People often use “swear,” “promise,” “vow” and “testify” as though they mean the same thing. They do not. A religious oath invokes the object of the oath to strengthen a claim or bind a future action. That is why the object matters. A promise commits the speaker to another person. A vow may commit an act of devotion. Testimony reports what a witness knows. Everyday English can blur these categories, but a careful learner should not.

The Qur’an treats oaths as meaningful speech while recognising that not every expression has the same deliberateness.

Qur’an 5:89 distinguishes thoughtless or unintentional oath language from deliberately contracted oaths. It also gives the expiation for a broken deliberate oath. This is important evidence, but it must not be turned into an automatic online calculator. Whether a specific sentence was a binding oath, and whether its expiation applies, is a fiqh question for someone who can hear the complete words and intention.

The verse also ends by telling believers to guard their oaths. This encourages restraint. A person who swears over every small detail makes solemn language cheap and creates repeated opportunities for error. Truth does not become stronger because it is surrounded by dramatic phrases.

Qur’an 16:91 joins covenants and confirmed oaths in a command to fulfil them. The context is responsibility, not performance. The speaker has made اللّٰه (ALLAH) a guarantor and must not treat that language as disposable. This is why a deliberate oath should never be used to manipulate trust.

Verse 94 makes deception explicit. A person may choose the correct object of an oath and still sin by lying, misleading or using solemn words to make another person lower their guard. The topic therefore has two questions, not one: “By whom did I swear?” and “Was what I said truthful and just?”

The warning against trading covenants and oaths for a small gain shows that oath language is accountable. It should not be used to win a sale, escape responsibility, dominate a family argument or make an unsupported story sound convincing. The right response is fewer oaths and more reliable character.

A deliberate oath also does not turn a wrong action into a duty. Someone might say, “I swore I would never speak to that relative again,” or use an oath to avoid making peace. The Qur’an later corrects that way of thinking: solemn wording must not become a barrier to goodness. The learner therefore needs more than a rule about the object of an oath. They need honesty about its content, a willingness to correct what is wrong and qualified help when breaking a binding oath may require expiation.

The hadith are severe—and must be read accurately

The clearest instruction appears in Sahih al-Bukhari’s Book of Witnesses. It is brief enough to remember and broad enough to guide both private speech and formal settings.

“Whoever has to take an oath should swear by اللّٰه (ALLAH) or remain silent.”

Sahih al-Bukhari 2679

Sahih al-Bukhari 6646 gives the living context. Ibn Umar reports that Umar was travelling with riders and swore by his father. The Messenger prohibited swearing by fathers and repeated the instruction to swear by اللّٰه (ALLAH) or keep quiet. Honour for one’s parents is not being condemned. The prohibited act is making a created parent the object of the oath.

Jami` at-Tirmidhi 1535 records another incident. Ibn Umar heard a man swear by the Ka’bah and corrected him with a report from the Messenger:

“Whoever swears by other than اللّٰه (ALLAH), he has committed disbelief or shirk.”

Jami` at-Tirmidhi 1535

The authentication record must be transparent. Al-Tirmidhi’s own closing note calls the hadith hasan. The same page on Sunnah.com displays the later Darussalam grade Sahih. Its Arabic commentary also records that some people of knowledge understood “disbelief or shirk” here as wording of intensification. Sunan Abi Dawud 3249 independently carries the prohibition and is displayed as Sahih according to Al-Albani.

These details protect the learner from two opposite errors. The first says, “It is only a figure of speech, so the hadith does not matter.” That dismisses an authenticated warning. The second points at any speaker and declares them outside Islam from one phrase. That ignores scholarly explanation, intention, veneration and the difference between a general classification and a verdict on a person.

How scholars explain the classification

A widely recorded explanation treats swearing by a created thing as lesser shirk when the speaker has not given it the same veneration that belongs to اللّٰه (ALLAH). If a person were genuinely to treat the created object as equal in Divine veneration or independent unseen power, the matter would be far more serious. That major classification cannot be inferred safely from an accent, family habit or short recording.

Reviewed scholarly summaries do not use identical labels for every habitual slip. Dorar’s English Aqidah Encyclopedia uses the lesser-shirk classification when equal Divine veneration is absent. Jordan’s General Iftaa Department describes a thoughtless customary expression as a vain oath and presents non-Divine swearing as disliked unless equal veneration is intended. The authentic prohibition remains the shared practical conclusion; the difference is recorded rather than hidden.

This article therefore does not issue a personal creed verdict. It says what the hadith says, gives the commonly stated classification, acknowledges the reviewed terminology difference and sends an actual case for qualified assessment.

Five situations that should never be collapsed into one

“Swearing on the Qur’an” also needs a separate answer. Scholars examine what the speaker intends by the expression and discuss the Divine attribute of speech. A short article about non-Divine oaths should not silently resolve that theology and fiqh question.

Correct a slip with tawheed, truth and a better habit

Sahih al-Bukhari 6107 records a direct correction for someone who mistakenly used the names of pre-Islamic deities in an oath: affirm that none has the right to be worshipped except اللّٰه (ALLAH). Sunan an-Nasa’i 3777, graded Sahih by Darussalam on the cited page, contains a fuller report that also includes seeking refuge and not returning to the expression.

We should keep the reports distinct rather than manufacturing one blended quotation. Their shared direction is clear: restore tawheed on the tongue, reject the old formula and do not repeat it. The response is correction, not a public spectacle.

1. Stop the phrase. Do not defend it merely because it is common.
2. Affirm tawheed and seek forgiveness. Let the correction point back to worship of اللّٰه (ALLAH) alone.
3. Tell the truth plainly. Most conversations need no oath at all.
4. Repair any deception. If the phrase helped secure money, trust or an advantage dishonestly, correct the human harm as well.
5. Ask about a real binding oath. Do not guess at expiation or legal effect from a search result.

Teaching the same lesson at different ages

Ages 5–7: say, “Tell the truth without making big oaths. If an oath is really needed, it belongs to اللّٰه (ALLAH) alone.” Do not frighten a child with disbelief labels or ask them to repeat prohibited examples.

Ages 8–11: make three neutral cards: oath, promise and quotation. Read a simple description and let the child choose the correct card. Practise replacing dramatic phrases with “Yes, that is true” or “I do not know.”

Ages 12–15: compare Qur’an 5:89 with Sahih al-Bukhari 2679. Ask three separate questions: Was an oath intended? What was invoked? Was the statement truthful? This prevents one clue from answering every question.

Ages 16+ and adults: inspect Jami` at-Tirmidhi 1535 in full, including al-Tirmidhi’s grade and intensification note. Compare two reviewed scholarly classifications of habitual speech and explain why disagreement over terminology does not cancel the prohibition.

The exercise works without images. A learner can hear five spoken scenarios and name the category aloud. The educational goal is a truthful tongue, reverence for اللّٰه (ALLAH) and calm correction—not a collection of phrases for accusing other people.
