The Force of the Kāf in Qur’an 42:11
A faithful, forceful rendering is:
The wording does not mean that Allah possesses a “likeness” and that nothing resembles that likeness. The major commentators agree on the theological meaning; they differ mainly over how the Arabic achieves its unusual emphasis.
The Grammatical Structure
| Element | Transliteration | Function | Basic sense |
|---|---|---|---|
| لَيْسَ | laysa | Negative copular verb | “is not/there is not” |
| كَـ | ka- | Preposition of comparison | “like/as” |
| مِثْلِ | mithli | Noun of comparison | “equal, counterpart, one like…” |
| ـهِ | -hi | Pronoun referring to Allah | “Him” |
| شَيْءٌ | shayʾun | Delayed noun of لَيْسَ (laysa), or ism laysa | “anything” |
كَمِثْلِهِ (ka-mithlihi) is a prepositional phrase—جَارٌّ وَمَجْرُورٌ (jārrun wa-majrūrun)—occupying the syntactic position of the fronted predicate of لَيْسَ (laysa). شَيْءٌ (shayʾun) is its delayed noun: اسْمُ لَيْسَ الْمُؤَخَّرُ (ismu laysa al-muʾakhkharu). Within the phrase, مِثْلِ is formally genitive after the kāf and begins an iḍāfah; the attached pronoun ـهِ completes it. Because شَيْءٌ is indefinite under negation, it means anything whatsoever, without exception.
A wooden rendering would be, “There is no thing like His like,” but that produces misleading implications in English. In Arabic, مِثْلُهُ (mithluhu) can mean “His equal” or “one comparable to Him” without asserting that such an equal actually exists.
Why Both Kāf and Mithl?
Both ordinarily express comparison:
| Arabic | Transliteration | Meaning |
|---|---|---|
| كَزَيْدٍ | ka-Zaydin | like Zayd |
| مِثْلُ زَيْدٍ | mithlu Zaydin | one like Zayd |
| كَمِثْلِ زَيْدٍ | ka-mithli Zaydin | literally, “like one like Zayd” |
The tafsīr tradition offers three principal analyses. The dispute is grammatical and rhetorical, not a disagreement about Allah’s incomparability.
| Analysis | Underlying paraphrase | What the kāf contributes | Major representatives |
|---|---|---|---|
| The kāf is augmentative or emphatic | لَيْسَ مِثْلَهُ شَيْءٌLaysa mithlahu shayʾun. | It repeats and reinforces comparison inside the negation. | Al-Ṭabarī as one view, al-Māturīdī, Ibn ʿAṭiyyah, many grammarians, and Ibn ʿĀshūr |
| مِثْل (mithl) is the reinforcing element | لَيْسَ هُوَ كَشَيْءٍLaysa huwa ka-shayʾin. | The kāf retains its ordinary “like” meaning. | Recorded by al-Ṭabarī, al-Baghawī, and al-Qurṭubī |
| Neither is additional: the construction is an Arabic kināyah | “Nothing is like one such as Him” | The entire construction functions as an emphatic kināyah. | Al-Zamakhsharī, al-Rāzī, al-Bayḍāwī, Abū Ḥayyān, and al-Ālūsī |
The Emphatic-Kāf Analysis
On the first reading, grammarians call the kāf زَائِدَةً (zāʾidah) or صِلَةً (ṣilah). “Additional” is a technical syntactic term; it does not mean “meaningless.”
Without the kāf, the bare proposition remains complete:
The Qur’anic expression is more forceful. It places two expressions of comparison—one particle and one noun—within the scope of لَيْسَ (laysa):
Ibn ʿĀshūr describes the result precisely:
The kāf does not first create a stronger kind of resemblance so that only this stronger resemblance can then be denied. Both comparison markers are already governed by لَيْسَ. The result is approximately: “Nothing is like Him—nothing at all.”
Al-Māturīdī likewise explains the construction as follows:
He then summarizes Allah as:
Old Arabic usage supports this doubling. Commentators cite the following poetic phrase:
The Kināyah Explanation
Al-Zamakhsharī’s preferred explanation begins with an Arabic idiom:
The speaker intends, “You are not miserly,” but says it more emphatically. Generosity is presented as so characteristic of the person that even anyone answering to his description would necessarily possess it.
Likewise, مِثْلِهِ (mithlihi) in the verse does not posit an actual second God. It is a hypothetical or idiomatic expression. The construction denies even the possibility of placing anything in a class or category with Allah. See al-Zamakhsharī and al-Rāzī on Qur’an 42:11.
Al-Bayḍāwī largely reconciles this with the emphatic-kāf analysis. Someone who calls the kāf “additional” means that the basic proposition is لَيْسَ مِثْلَهُ شَيْءٌ (laysa mithlahu shayʾun), while acknowledging that the Qur’anic circumlocution is more emphatic. See al-Bayḍāwī’s commentary.
Two Secondary Explanations
Al-Rāzī adds an ingenious logical argument. Suppose Allah had a counterpart. Since resemblance is reciprocal, Allah Himself would be something like that counterpart. Yet the verse says that no “thing” is like His supposed counterpart. The assumption therefore contradicts the sentence itself. This preserves every word literally, although Ibn ʿĀshūr regards this type of explanation as strained and obscure.
Al-Bayḍāwī also records the interpretation:
That is true as an implication, but it is less comprehensive if treated as the entire meaning. The verse denies comparability in Allah’s being, attributes, acts, and perfection—not merely in one category. See al-Bayḍāwī on Qur’an 42:11.
What the Kāf Does—and Does Not—Add
A popular explanation assigns two fixed degrees:
- مِثْل (mithl) supposedly means an exact duplicate;
- كَـ (ka-) supposedly means merely partial resemblance;
- therefore, exact and partial resemblance are separately denied.
That can function as a devotional paraphrase, but it is not the principal classical grammatical account. The major grammarians generally treat كَـ and مِثْل here as overlapping expressions of comparison. Their force comes from their combination under negation, not from a rigid taxonomy of “exact” and “partial” likeness.
The safest conclusion is that the kāf is syntactically augmentative but rhetorically powerful: it seals and reinforces the exclusion of comparison. Its universal scope comes principally from the indefinite شَيْءٌ (shayʾun) under negation.
The Immediate Context: Pairs and the Unpaired Creator
The preceding words speak of created pairs:
Allah created human and animal pairs and causes created life to multiply through pairing. Then comes:
The contrast is significant:
- The humans and livestock named here belong to created kinds and pairs.
- Their multiplication occurs through counterparts.
- The Creator of that entire order is not one member of it.
- He has no mate, counterpart, parent, child, genus, or equal.
Ibn Kathīr therefore paraphrases:
Ibn ʿĀshūr connects the verse specifically with refuting the pagan attribution of daughters to Allah. More broadly, its Creator–creation distinction excludes a consort or any supposed membership in a divine species. See Ibn ʿĀshūr on Qur’an 42:11.
Incomparability Without Emptying Revelation of Meaning
The verse continues:
The two halves govern one another:
| Qur’anic wording | Function |
|---|---|
| لَيْسَ كَمِثْلِهِ شَيْءٌLaysa ka-mithlihi shayʾun. | Excludes assimilation. |
| وَهُوَ السَّمِيعُ الْبَصِيرُWa-huwa al-Samīʿu al-Baṣīru. | Affirms the attributes named in revelation. |
Allah truly hears and sees, but His hearing and seeing are not creaturely sensory processes dependent on organs, sound waves, light, distance, concentration, or acquired information.
The Qur’an can also describe a human being as:
Sharing a word does not imply equality of reality or manner. Created hearing is originated, limited, and dependent; divine hearing is perfect, unacquired, and unlimited.
For Sunni theology, this balance is often summarized:
Atharī, Ashʿarī, and Māturīdī authors differ over the treatment of certain attribute texts, but they agree that nothing in revelation authorizes imagining a creaturely how for Allah. Other exegetical traditions formulate the attributes differently, yet commentators as doctrinally diverse as al-Māturīdī, al-Zamakhsharī, al-Rāzī, Ibn Kathīr, al-Ālūsī, and al-Ṭabāṭabāʾī converge on the verse’s absolute denial of a divine peer.
Kāf and Mithl in Hadith Transmission
A Close Linguistic Parallel
A particularly close parallel occurs in the hadith of al-Mustawrid concerning this world in comparison with the Hereafter. A sound route preserved by Aḥmad reads:
Ṣaḥīḥ Muslim transmits the same comparison with مِثْل (mithl) alone:
The hadith corpus therefore preserves the same comparison through:
- كَمِثْلِ (ka-mithli),
- مِثْلُ (mithlu), and
- in another authenticated transmission, كَمَا (ka-mā).
For a كَمَا wording, see the route in Ṣaḥīḥ Ibn Ḥibbān, no. 4330 in the cited numbering.
These variants provide a close linguistic parallel: in this ordinary comparison, كَمِثْلِ does not posit a second ontological “likeness of what the finger does.” The variants do not by themselves settle the syntax of Qur’an 42:11, but they show that kāf plus mithl can function as an idiomatically reinforced comparison.
Does the Exact Qur’anic Phrase Occur in a Hadith?
The wording appears in explanatory material transmitted by al-Tirmidhī:
It should not, however, be cited confidently as an independently authenticated Prophetic statement. The connected report through Ubayy appears as al-Tirmidhī 3364. In the following report, 3365, al-Tirmidhī presents the route from Abū al-ʿĀliyah without Ubayy and calls it more correct. The cited Darussalam presentation grades 3364 weak, although published gradings differ. It is safest to describe the wording as explanatory material within a tafsīr report preserved by al-Tirmidhī.
The Underlying Idea in Sound Hadith
The underlying idea is firmly represented in sound hadith. In a sound hadith qudsī, Allah says:
In the prophetic supplication:
Another sound hadith states:
Here the comparison concerns the clarity of the two acts of seeing, not a resemblance between Allah’s essence and the moon. It demonstrates that a kāf-comparison is limited to the respect established by its context.
Final Synthesis
Regarding the additional كَـ (ka-) specifically, the cleanest grammatical explanation is that it repeats the idea of comparison inside the scope of لَيْسَ (laysa), thereby reinforcing its negation. The strongest rhetorical alternative treats the whole phrase as an Arabic kināyah. Both yield the same conclusion: the kāf does not posit a second likeness; it makes the impossibility of comparison more emphatic.
