The Qur’anic Root A TH M

1. Early usage: slowness and delay

Ibn Fāris writes that this root points to one basic meaning, slowness and delay, and cites ناقة آثمة (nāqah āthimah) for a she-camel that falls behind. He then explains ithm in the same direction because its bearer is slow and falls behind in goodness. Other sources also record āthimah for a camel that is slow or weary in its movement.

The verse of al-Aʿshā that lexicographers quote for this use is also recorded in his collected poetry:

جُمالِيَّةٍ تَغْتَلي بِالرِّدافِ
إِذا كَذَّبَ الآثِماتُ الهَجيرا

Jumāliyyatin taghtalī bi-r-ridāfi / Idhā kadhdhaba l-āthimātu l-hajīrā.

Here al-āthimāt refers to she-camels that fall short of the expected movement or slow down in the midday heat. The verse itself can be traced in al-Aʿshā’s collected poetry.

A chronological caution nevertheless remains. Al-Aʿshā also lived near the emergence of Islam, and the precise date of this verse cannot be established merely from its attribution within his collected poetry. This witness therefore establishes the use of “slowness” in early Arabic, but independent chronological evidence is needed to call this particular verse definitively pre-Qur’anic.

This evidence allows us to say that “slowness and delay” was an actual branch of the root. The analysis that “sin holds a person back from goodness” also has a lexical history. But we should not add a new image such as “ithm is a load weighing upon a person’s shoulders and slowing their movement.” The available witnesses speak of slowing down and falling behind, not the weight of a burden.

2. إِثْم (ithm) in the Qur’an: sin attributed to a person

One of the clearest constructions occurs in An-Nisa 4:111:

وَمَنْ يَكْسِبْ إِثْمًا فَإِنَّمَا يَكْسِبُهُ عَلَىٰ نَفْسِهِ

Wa-man yaksib ithman fa-innamā yaksibuhu ʿalā nafsih.

“Whoever acquires a sin acquires it only against themselves.”

Ithm in this verse is something acquired, whose responsibility returns to the person themselves.

Al-Anam 6:120 repeats this language of acquisition:

إِنَّ الَّذِينَ يَكْسِبُونَ الْإِثْمَ سَيُجْزَوْنَ بِمَا كَانُوا يَقْتَرِفُونَ

Inna lladhīna yaksibūna l-ithma sa-yujzawna bi-mā kānū yaqtarifūn.

“Those who acquire sin will be recompensed for what they used to commit.”

An-Nur 24:11 also states, concerning the incident of ifk, the false accusation:

لِكُلِّ امْرِئٍ مِنْهُمْ مَا اكْتَسَبَ مِنَ الْإِثْمِ

Li-kulli mriʾin minhum mā ktasaba mina l-ithm.

“For each of them is the share of sin that they acquired.”

Ithm in the Qur’an is therefore not merely the name of an outward act; it is moral responsibility generated for a person by an act or condition attributable to them. Across the root’s occurrences, acquisition, recompense, bearing responsibility, and the direct attribution of ithm to people repeatedly accompany the word.

Ithm can be inward

Al-Baqarah 2:283 says:

وَلَا تَكْتُمُوا الشَّهَادَةَ وَمَنْ يَكْتُمْهَا فَإِنَّهُ آثِمٌ قَلْبُهُ

Wa-lā taktumū sh-shahādata wa-man yaktumhā fa-innahu āthimun qalbuh.

“Do not conceal testimony; whoever conceals it has a sinful heart.”

Here the description āthim is attributed directly to the heart.

Al-Anam 6:120 also speaks of:

ظَاهِرَ الْإِثْمِ وَبَاطِنَهُ

Ẓāhira l-ithmi wa-bāṭinah.

“The outward and inward of sin.”

And Al-Hujurat 49:12 says:

إِنَّ بَعْضَ الظَّنِّ إِثْمٌ

Inna baʿḍa ẓ-ẓanni ithm.

“Indeed, some suspicion is sin.”

The field of ithm therefore cannot be restricted to an outward crime, bodily harm, or observable conduct. The Qur’an also uses it for the inward realm.

The severity of ithm is not uniform

The word itself does not establish a fixed degree of sin. The Qur’an speaks of:

إِثْمًا عَظِيمًا

Ithman ʿaẓīmā.

A tremendous sin.

An-Nisa 4:48

And:

إِثْمًا مُبِينًا

Ithman mubīnā.

A manifest sin.

An-Nisa 4:20; An-Nisa 4:50; An-Nisa 4:112

And:

كَبَائِرَ الْإِثْمِ

Kabāʾira l-ithm.

Major sins.

Ash-Shura 42:37; An-Najm 53:32

These are among its expressions.

The enormity, manifest character, or magnitude of ithm thus comes from the qualification and context. Ithm itself is a moral category that can have different degrees.

3. The construction “ithm + ʿalā”: who bears responsibility?

A recurring Qur’anic construction deserves separate attention.

Al-Baqarah 2:181 states:

فَإِنَّمَا إِثْمُهُ عَلَى الَّذِينَ يُبَدِّلُونَهُ

Fa-innamā ithmuhu ʿalā lladhīna yubaddilūnah.

“Its sin rests only upon those who alter it.”

In Al-Baqarah 2:173:

فَلَا إِثْمَ عَلَيْهِ

Fa-lā ithma ʿalayh.

There is no sin upon that person.

The same construction occurs twice in Al-Baqarah 2:203:

فَلَا إِثْمَ عَلَيْهِ

Fa-lā ithma ʿalayh.

There is no sin upon that person.

In Al-Baqarah 2:182, too, after setting matters right between the parties, it says:

فَلَا إِثْمَ عَلَيْهِ

Fa-lā ithma ʿalayh.

There is no sin upon that person.

In this group of verses, the preposition ʿalā, upon, connects ithm with the person who bears responsibility; in the negative construction, it expresses the absence of that responsibility. The clearest example is Al-Baqarah 2:181, which attributes altering a bequest to a group and explicitly places the resulting ithm “upon” those same people who altered it.

This is an important Qur’anic construction, not a rule that “ithm always occurs with ʿalā.” In many instances the Qur’an uses ithm without ʿalā: يَكْسِبْ إِثْمًا (yaksib ithman), “acquires a sin”; فِيهِمَا إِثْمٌ (fīhimā ithm), “in them both is sin”; بِالْإِثْمِ وَالْعُدْوَانِ (bi-l-ithmi wa-l-ʿudwān), “in sin and aggression”; and بَعْضَ الظَّنِّ إِثْمٌ (baʿḍu al-ẓanni ithm), “some suspicion is sin.”

What can be said with confidence is that the construction “ithm + ʿalā” occurs several times in the Qur’an when responsibility for ithm is explicitly placed upon or removed from a person.

4. Differences from nearby roots and concepts

A TH M (أَثَم, atham) compared with AYN D W (عَدَو, ʿadaw): ithm and ʿudwān

The Qur’an places ithm and ʿudwān beside one another several times:

وَلَا تَعَاوَنُوا عَلَى الْإِثْمِ وَالْعُدْوَانِ

Wa-lā taʿāwanū ʿalā l-ithmi wa-l-ʿudwān.

Do not cooperate in sin and aggression.

Al-Maidah 5:2

يُسَارِعُونَ فِي الْإِثْمِ وَالْعُدْوَانِ

Yusāriʿūna fī l-ithmi wa-l-ʿudwān.

They hasten in sin and aggression.

Al-Maidah 5:62

يَتَنَاجَوْنَ بِالْإِثْمِ وَالْعُدْوَانِ

Yatanājawna bi-l-ithmi wa-l-ʿudwān.

They converse privately in sin and aggression.

Al-Mujadilah 58:8

ʿUdwān tends toward crossing a limit and transgression. Ithm is broader and does not necessarily require direct aggression against another person; for example, “some suspicions” can be ithm.

In this pairing, “sin and aggression” is therefore more precise than “sin and sin.” The two words’ appearance together indicates a distinction, although conjunction alone does not establish an absolute boundary between them.

A TH M (أَثَم, atham) compared with F H SH (فَحَش, faḥash): ithm and fāḥishah

Al-Araf 7:33 distinguishes among:

الْفَوَاحِشَ ... وَالْإِثْمَ وَالْبَغْيَ

Al-fawāḥisha … wa-l-ithma wa-l-baghy.

Indecencies … and sin and transgression.

Ash-Shura 42:37 and An-Najm 53:32 also speak of:

كَبَائِرَ الْإِثْمِ وَالْفَوَاحِشَ

Kabāʾira l-ithmi wa-l-fawāḥish.

Major sins and indecencies.

These are named together in those passages.

Fuḥsh concerns intense ugliness and exceeding bounds in reprehensibility, whereas ithm is a more general category for sin and moral responsibility. Not every ithm is therefore necessarily a fāḥishah, although fawāḥish can fall within the realm of ithm. Lexical sources themselves also explain fuḥsh through severe reprehensibility.

A TH M (أَثَم, atham) compared with KH T A (خَطَأ, khaṭaʾ): ithm and khaṭīʾah

An-Nisa 4:112 says:

وَمَنْ يَكْسِبْ خَطِيئَةً أَوْ إِثْمًا ثُمَّ يَرْمِ بِهِ بَرِيئًا

Wa-man yaksib khaṭīʾatan aw ithman thumma yarmi bihi barīʾā.

“Whoever acquires a fault or a sin, then casts it upon an innocent person…”

The presence of khaṭīʾah and ithm beside one another shows that the Qur’an retains the possibility of distinguishing them, but this verse alone does not define their precise boundary.

In Al-Baqarah 2:182, too, early commentators sometimes distinguished janaf and ithm in terms of error and deliberateness. This may show that conscious responsibility stands out in some uses of ithm, but must not become an absolute rule that “ithm is always intentional” and every nearby term always unintentional.

The full distinction concerning khaṭīʾah must be determined in an independent study of KH T A. The A TH M article can only show that the Qur’an treats these as two designations that can be joined by a conjunction, rather than reducing them to one word.

A TH M (أَثَم, atham) compared with DH N B (ذَنَب, dhanab): ithm and dhanb

Both dhanb and ithm are often translated as “sin” in English. But distinguishing them should not involve inventing an image that lexical sources have not established.

For DH N B, Ibn Fāris records three separate basic meanings: offense and sin, the rear of something, and a share or portion. He presents the branch dhanb, an offense, separately from dhanab, an animal’s tail or end. Their similarity in written form therefore does not authorize saying that sin was named dhanb because it trails behind a person like a tail.

Different tendencies also appear in Qur’anic usage. Dhanb repeatedly occurs in constructions of seeking forgiveness and granting pardon, while ithm prominently appears in constructions such as acquiring ithm, the absence of ithm upon a person, responsibility for ithm resting upon someone, cooperating in ithm, and attributing ithm to the heart.

This difference in usage can help compare the roots, but should not become an absolute formula. Both belong to the realm of sin, and their full boundary requires an independent study of DH N B.

A TH M (أَثَم, atham) compared with S W A (سَوَأ, sawaʾ): ithm and sayyiʾah

Sayyiʾah is also often translated as “sin,” but its range is broader than that of ithm.

Ibn Fāris places the root S W A in the field of “ugliness and badness,” and understands sayyiʾah within that field.

The Qur’an sometimes uses sayyiʾah for a morally bad act:

وَمَنْ جَاءَ بِالسَّيِّئَةِ فَلَا يُجْزَىٰ إِلَّا مِثْلَهَا

Wa-man jāʾa bi-s-sayyiʾati fa-lā yujzā illā mithlahā.

Whoever comes with a bad deed will be recompensed only with its like.

Al-Anam 6:160

The same word can also refer to an unwelcome event. An-Nisa 4:78 speaks of people who attribute a ḥasanah, something good that comes to them, to The God, but attribute a sayyiʾah that comes to them to the Prophet. In this context, sayyiʾah is not their sin, but something unwelcome that befalls them. Early commentaries explicitly recognize this difference in usage as well.

Sayyiʾah in the Qur’an can therefore be a bad act or a bad condition or event. Ithm, in its central Qur’anic usage, belongs specifically to sin and moral responsibility. The Qur’an does not say that drought or military defeat struck someone as ithm; ithm is connected with human action and moral responsibility.

5. آثِم (āthim) and أَثِيم (athīm): a person described by ithm

The Qur’an uses آثِم (āthim) three times and أَثِيم (athīm) seven times.

Āthim is the direct active participle. In Al-Baqarah 2:283:

فَإِنَّهُ آثِمٌ قَلْبُهُ

Fa-innahu āthimun qalbuh.

Indeed, that person’s heart is sinful.

And in Al-Insan 76:24:

وَلَا تُطِعْ مِنْهُمْ آثِمًا أَوْ كَفُورًا

Wa-lā tuṭiʿ minhum āthiman aw kafūrā.

Do not obey any sinful person or persistent practitioner of kufr among them.

These are instances of this form.

Athīm follows the faʿīl pattern, and lexical sources record a tendency toward greater intensity or persistence in ithm. Lane likewise identifies athīm as stronger in meaning than āthim. Qur’anic usage accords with this tendency, since athīm almost always appears beside severe descriptions:

كَفَّارٍ أَثِيمٍ

Kaffārin athīm.

Persistently committing kufr and sinful.

Al-Baqarah 2:276

خَوَّانًا أَثِيمًا

Khawwānan athīmā.

Deeply treacherous and sinful.

An-Nisa 4:107

أَفَّاكٍ أَثِيمٍ

Affākin athīm.

A fabricator of falsehood, sinful.

Ash-Shuara 26:222; Al-Jathiyah 45:7

مُعْتَدٍ أَثِيمٍ

Muʿtadin athīm.

A transgressor, sinful.

Al-Qalam 68:12; Al-Mutaffifin 83:12

This pattern allows us to say that athīm in Qur’anic usage tends toward a more severe and enduring description. But the faʿīl pattern alone does not authorize translating it as “very sinful” in every occurrence or assigning a mathematical degree to its intensity. Āthim and athīm overlap; context must determine the degree of intensity.

6. أَثَام (athām) in Al-Furqan 25:68

The Qur’an’s sole occurrence of أَثَام (athām) is:

وَمَنْ يَفْعَلْ ذَٰلِكَ يَلْقَ أَثَامًا

Wa-man yafʿal dhālika yalqa athāmā.

“Whoever does that will meet athām.”

The next verse immediately says:

يُضَاعَفْ لَهُ الْعَذَابُ يَوْمَ الْقِيَامَةِ

Yuḍāʿaf lahu l-ʿadhābu yawma l-qiyāmah.

“The punishment will be multiplied for that person on the Day of Resurrection.”

Lexical sources record both ithm itself and the recompense and punishment of ithm for athām. Ibn Fāris likewise relates al-athām to both ithm and punishment, and later linguistic analyses identify “the recompense of ithm” as one of this form’s main meanings. The Qur’anic morphological index itself also labels this occurrence as “punishment.”

The Qur’anic context strengthens the second direction: yalqa athāman, “will meet athām,” is then explained by yuḍāʿaf lahu al-ʿadhāb, “the punishment will be multiplied for him.” “Punishment for sin” or “recompense for sin” is therefore more appropriate for understanding this passage than “sin” alone.

Some exegetical reports identify Athām as the name of a valley in Hell. Such identifications belong to the history of interpretation, but are not required by the root itself or the verse’s construction. A basic translation should not turn athām into the proper name of a place unless there is independent, explicit evidence from the Qur’an itself.

7. تَأْثِيم (taʾthīm): inducing sin, making sinful, or attributing ithm

Taʾthīm occurs only twice in the Qur’an:

يَتَنَازَعُونَ فِيهَا كَأْسًا لَا لَغْوٌ فِيهَا وَلَا تَأْثِيمٌ

Yatanāzaʿūna fīhā kaʾsan lā laghwun fīhā wa-lā taʾthīm.

They pass a cup among themselves there, with neither idle talk nor taʾthīm in it.

At-Tur 52:23

And:

لَا يَسْمَعُونَ فِيهَا لَغْوًا وَلَا تَأْثِيمًا

Lā yasmaʿūna fīhā laghwan wa-lā taʾthīmā.

They hear neither idle talk nor taʾthīm there.

Al-Waqiah 56:25

Taʾthīm is the Form II verbal noun derived from ithm. Early exegetical sources explain it through several related expressions: something that makes a person āthim, an act that brings about ithm, lying, insulting speech, or people not attributing ithm to one another. In At-Tur, al-Ṭabarī understands it as the absence of an act that makes its doer sinful, and also quotes Mujāhid’s wa-lā yuʾthimūn. Al-Qurṭubī likewise says that the heavenly cup does not make them āthim.

This variety shows that “sin” alone does not fully convey the Form II construction, but “accusation of sin” is also too narrow for both verses.

In At-Tur 52:23, taʾthīm stands in one construction with the cup and laghw, idle talk; in Al-Waqiah 56:25, the verb يَسْمَعُونَ (yasmaʿūna), they hear, shows that what is denied under taʾthīm in that context is also something audible.

It is therefore better to keep the basic meaning open: what brings about ithm, makes a person āthim, or attributes ithm to them. The precise translation of each verse must be determined separately from its own construction.

8. Was ithm a name for wine?

Some lexical sources report that ithm was among the names of khamr, wine, and quote a verse of poetry for it:

شَرِبْتُ الإِثْمَ حَتَّى ضَلَّ عَقْلِي

Sharibtu l-ithma ḥattā ḍalla ʿaqlī.

I drank “ithm” until my reason went astray.

The early lexicographers themselves, however, do not agree on the reliability of this claim.

Ibn Fāris reports it from al-Akhfash and immediately says he does not know how sound the report is. Lisān al-ʿArab also quotes Abū Bakr as saying that ithm’s being a recognized name for khamr is not established. Ibn Sīdah suggests that if khamr was called ithm in poetry, it may have been because drinking it was ithm, not because ithm was wine’s primary name.

The Qur’an itself also distinguishes the two words in Al-Baqarah 2:219:

يَسْأَلُونَكَ عَنِ الْخَمْرِ وَالْمَيْسِرِ قُلْ فِيهِمَا إِثْمٌ كَبِيرٌ وَمَنَافِعُ لِلنَّاسِ وَإِثْمُهُمَا أَكْبَرُ مِنْ نَفْعِهِمَا

Yasʾalūnaka ʿani l-khamri wa-l-maysiri qul fīhimā ithmun kabīrun wa-manāfiʿu li-n-nāsi wa-ithmuhumā akbaru min nafʿihimā.

“They ask you about khamr and maysir. Say: in both is great sin and benefits for people, but their sin is greater than their benefit.”

In this verse, khamr is the subject under discussion, and ithm is something within it. At least in this passage, there is therefore no doubt that ithm does not mean wine itself.

The verse also makes another important point. The Qur’an does not deny the existence of benefits, yet regards ithm as greater than those benefits. Ithm therefore cannot be defined as “absence of benefit,” “material harm,” or “something with no use.” The word’s moral judgment is not identical to a simple calculation of material profit and loss.

Taken together, the witnesses provide no reason to translate ithm as “wine” in Qur’anic verses.

9. Translation guidance

In English, “sin” is the most natural basic equivalent of ithm. It is concise and preserves the word’s moral field. The root explanation should clarify that the Qur’an treats ithm as something a person acquires and for which they can bear responsibility.

In the construction:

فَلَا إِثْمَ عَلَيْهِ

Fa-lā ithma ʿalayh.

“There is no sin upon that person.”

This is a natural, precise translation, and the construction with ʿalā preserves the absence of responsibility resting upon the person.

آثِم (āthim) means “sinful.”

أثِيم (athīm) likewise basically means “sinful,” with a tendency toward a more intense or enduring description in Qur’anic usage. This tendency should be expressed in translation through wording such as “very sinful” only when the context also supports it.

أَثَام (athām) in Al-Furqan 25:68 is better understood, in light of what follows, as “punishment for sin” or “recompense for sin.”

تَأْثِيم (taʾthīm) has no simple, exactly matching one-word English equivalent. Its field lies among inducing sin, making someone āthim, and attributing ithm. The translations of At-Tur 52:23 and Al-Waqiah 56:25 should be determined separately.

Conclusion

The root أ ث م (A TH M) forms a clear Qur’anic family in sin and moral responsibility. Its central word, ithm, is something a person acquires and can bear responsibility for. The Qur’an speaks of outward and inward ithm, ithm of the heart, and even ithm in some suspicions. The word is therefore not confined to an outward crime or observable behavior.

The recurring construction ithm + ʿalā also highlights this aspect. When the Qur’an explicitly attributes responsibility for ithm to someone or denies it of them, it says ithmuhu ʿalā…, “its sin is upon…,” or lā ithma ʿalayhi, “there is no sin upon him.” This is only one of the word’s constructions, however; in many verses ithm occurs without ʿalā.

The same root is also recorded in early Arabic for slowness and falling behind. Ibn Fāris uses that occurrence to connect moral ithm with being held back from goodness. This explanation has an actual lexical basis, but should not be extended into images without evidence. Early sources do not define ithm as “a heavy burden that slows a person down.”

Comparison with nearby words clarifies its boundaries further. ʿUdwān tends toward transgression and crossing a limit; fāḥishah toward severe reprehensibility; sayyiʾah can denote either a bad act or an unwelcome event; khaṭīʾah is a separate designation that the Qur’an places alongside ithm; and dhanb has its own word family for sin whose historical connection with “a tail or the end of something” should not be invented without evidence. Ithm’s prominent Qur’anic feature is the attribution of moral responsibility to a person.

Āthim describes a person characterized by ithm, while athīm in Qur’anic usage tends toward a more intense, enduring description. Athām in Al-Furqan approaches the punishment of ithm. Taʾthīm, in two descriptions of Paradise, expresses the absence of what brings a person into ithm or attributes ithm to them.

The lexical report that ithm was a name for wine is also uncertain, and early lexicographers themselves questioned it. In Al-Baqarah 2:219, the Qur’an distinguishes khamr from ithm and says that ithm exists in khamr and maysir. In Qur’anic use, ithm is therefore sin and moral responsibility, not a name for wine.

A cautious synthesis of the root is:

A TH M: a family for sin and moral responsibility attributable to a human being. Ithm is connected with a person’s conduct, speech, or inward condition; it can be acquired, and responsibility for it can rest upon that person. Early Arabic also records this root for slowness and falling behind, and linking ithm with being held back from goodness is a recognized lexical explanation. But this connection should not be turned into a broader image or derivational history without evidence.
