The Qur’anic Root Ṣ L Y
From taking warmth from a fire to entering it
The Qur’anic uses of ص ل ي concern fire and exposure to its heat. Sometimes people approach a fire to benefit from its warmth: this is the use of تَصْطَلُونَ in the story of Moses. In most other occurrences, a person is exposed to a burning fire and endures its heat. In the causative forms, someone else places that person in this condition.
The first use prevents us from defining the family simply as “punishment” or “Hell.” A person warming themselves beside a fire also falls within this semantic field.
The family occurs 25 times in the Qur’an: 13 Form I verbs, one Form II verb, four Form IV verbs, two Form VIII verbs, one صِلِيّ, three active participles in the forms صَالِ / صَالُو, and one verbal noun تَصْلِيَة. The two instances of taṣṭalūna concern warming oneself; the other 23 concern punitive fire. In these passages, ṣālū is the plural active participle in a construct phrase, not a plural past-tense verb.
An initial definition can be stated as follows:
Ṣ L Y: exposure to fire and its heat, whether to receive warmth or endure its burning; in causative forms, placing another person in that condition. Warming oneself beside a fire and burning in it are different uses within this field.
Qur’anic forms
Pre-Qur’anic Arabic: an inscription and a poem
The Safaitic inscription SIJ 293 contains the form ʾṣly. The scholarly reading recorded in OCIANA identifies it as a causative form of “burn/roast” and translates it in this sentence as “made a burnt offering.” This is evidence from a pre-Islamic linguistic setting, but the entry does not give a precise date for this particular inscription. Its distance from the Qur’an therefore cannot be expressed as a definite number of centuries.
The inscription supports a connection with fire. The particular meaning “burnt offering” belongs to the reading of this inscription and should not become the meaning of every Qur’anic occurrence.
The pre-Islamic poet al-Muraqqish al-Aṣghar says in “Li-bnati ʿAjlāna bi-l-jawwi rusūm,” transmitted in al-Mufaḍḍaliyyāt:
لَا تَصْطَلِي النَّارَ بِاللَّيْلِ وَلَا
تُوقَظُ لِلزَّادِ بَلْهَاءُ نَؤُومْ
“She does not warm herself at the fire by night, nor is she woken for food; carefree and given to sleep.” The poet describes a woman living in comfort. تصطلي النار concerns warming oneself at a fire and occurs here under negation; the subject is not punitive fire. The evidence is the word’s use in the pre-Islamic poem itself, rather than a later dictionary definition.
Yaṣlā: the person is exposed to the fire
The most frequent Qur’anic form is the Form I verb yaṣlā. In this construction, the person is in the fire and experiences its heat.
Al-Nisāʾ states:
إِنَّ الَّذِينَ يَأْكُلُونَ أَمْوَالَ الْيَتَامَىٰ ظُلْمًا إِنَّمَا يَأْكُلُونَ فِي بُطُونِهِمْ نَارًا ۖ وَسَيَصْلَوْنَ سَعِيرًا
“Those who consume orphans’ property unjustly consume only fire into their bellies, and they will enter a blazing fire.”
Al-Nisāʾ 4:10
“They will burn” is possible, but if burn is taken to mean complete consumption or the end of the object’s existence, it does not convey the full range of ṣaliya. The sentence centres on exposure to a blaze and its heat.
Al-Aʿlā makes this clearer:
سَيَذَّكَّرُ مَنْ يَخْشَىٰ وَيَتَجَنَّبُهَا الْأَشْقَى الَّذِي يَصْلَى النَّارَ الْكُبْرَىٰ ثُمَّ لَا يَمُوتُ فِيهَا وَلَا يَحْيَىٰ
“The one who fears will take heed, but the most wretched will avoid it: the one who enters the greater fire, then neither dies in it nor lives.”
Al-Aʿlā 87:10, 87:11, 87:12, 87:13
يَصْلَى النَّارَ does not result in the person’s immediate destruction here; the next verse itself states that they neither die in it nor live.
This continuation, however, comes from the context. It does not make “lasting a long time” an inherent meaning of Ṣ L Y in every occurrence.
Al-Ṭūr 52:16: enduring heat rather than immediate destruction
Al-Ṭūr offers another important example:
اصْلَوْهَا فَاصْبِرُوا أَوْ لَا تَصْبِرُوا سَوَاءٌ عَلَيْكُمْ ۖ إِنَّمَا تُجْزَوْنَ مَا كُنْتُمْ تَعْمَلُونَ
“Enter it and endure its heat; be patient or do not be patient—it is the same for you. You are recompensed only for what you used to do.”
Al-Ṭūr 52:16
فاصبروا أو لا تصبروا concerns a condition in which the person faces suffering. The sentence states that patience or impatience will not change the recompense.
Alongside al-Aʿlā 87:12, 87:13, this verse helps distinguish ṣaliya from the idea of immediate destruction in fire.
Al-Nisāʾ 4:56: continued suffering expressed by the context
Al-Nisāʾ states:
إِنَّ الَّذِينَ كَفَرُوا بِآيَاتِنَا سَوْفَ نُصْلِيهِمْ نَارًا كُلَّمَا نَضِجَتْ جُلُودُهُمْ بَدَّلْنَاهُمْ جُلُودًا غَيْرَهَا لِيَذُوقُوا الْعَذَابَ ۗ إِنَّ اللَّهَ كَانَ عَزِيزًا حَكِيمًا
“Those who disbelieve in Our signs—We will place them in a fire. Whenever their skins are cooked through, We will replace them with other skins so that they may taste the punishment. The God is mighty and wise.”
Al-Nisāʾ 4:56
Here نُصْلِيهِمْ نَارًا is followed by نَضِجَتْ جُلُودُهُمْ and then لِيَذُوقُوا الْعَذَابَ.
The verse depicts continued experience of punishment: the skins are cooked, replaced, and the punishment continues to be tasted.
This is important to the context, but the relationship should not be reversed by defining ṣaliya itself as “continuous and endless experience.” Continuation is established by the following clauses; the root expresses exposure to fire and its heat.
Causative forms: placing someone else in the fire
In Forms IV and II, an agent places someone else in the fire. This should not be labelled simply “intransitive versus transitive”: Form I itself takes النار as an object in يَصْلَى النَّارَ. The important difference here is the addition of an agent who causes the person to be exposed to fire.
Al-Nisāʾ states:
يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَأْكُلُوا أَمْوَالَكُمْ بَيْنَكُمْ بِالْبَاطِلِ إِلَّا أَنْ تَكُونَ تِجَارَةً عَنْ تَرَاضٍ مِنْكُمْ ۚ وَلَا تَقْتُلُوا أَنْفُسَكُمْ ۚ إِنَّ اللَّهَ كَانَ بِكُمْ رَحِيمًا وَمَنْ يَفْعَلْ ذَٰلِكَ عُدْوَانًا وَظُلْمًا فَسَوْفَ نُصْلِيهِ نَارًا ۚ وَكَانَ ذَٰلِكَ عَلَى اللَّهِ يَسِيرًا
“O you who have believed, do not consume one another’s property wrongfully, except through trade by mutual consent among you; and do not kill yourselves. The God is merciful towards you. Whoever does that in aggression and injustice—We will place him in a fire, and that is easy for The God.”
نُصْلِيهِ is Form IV. An agent places another person in the fire.
The same construction occurs in al-Nisāʾ 4:56 and 4:115 and al-Muddaththir 74:26.
Form II occurs in al-Ḥāqqah:
خُذُوهُ فَغُلُّوهُ ثُمَّ الْجَحِيمَ صَلُّوهُ ثُمَّ فِي سِلْسِلَةٍ ذَرْعُهَا سَبْعُونَ ذِرَاعًا فَاسْلُكُوهُ
“Seize him and shackle him; then consign him to the blazing fire; then thread him into a chain whose length is seventy cubits.”
صَلُّوهُ also places another person in the fire.
Al-Wāqiʿah uses the verbal noun of this form:
وَأَمَّا إِنْ كَانَ مِنَ الْمُكَذِّبِينَ الضَّالِّينَ فَنُزُلٌ مِنْ حَمِيمٍ وَتَصْلِيَةُ جَحِيمٍ إِنَّ هَٰذَا لَهُوَ حَقُّ الْيَقِينِ
“But if he is among the denying, astray ones, his reception is boiling water and being consigned to the blazing fire. This is indeed the truth of certainty.”
Al-Wāqiʿah 56:92, 56:93, 56:94, 56:95
Fire and heat remain central throughout these forms. The morphological difference chiefly concerns whether the person experiences that condition or another agent places them in it.
Taṣṭalūna: fire as a source of warmth
Two Qur’anic occurrences retain another application of the family.
Al-Naml states:
إِذْ قَالَ مُوسَىٰ لِأَهْلِهِ إِنِّي آنَسْتُ نَارًا سَآتِيكُمْ مِنْهَا بِخَبَرٍ أَوْ آتِيكُمْ بِشِهَابٍ قَبَسٍ لَعَلَّكُمْ تَصْطَلُونَ
“When Moses said to his family: I have seen a fire. I will bring you news from it, or bring you a burning brand, so that you may warm yourselves.”
Al-Naml 27:7
Al-Qaṣaṣ also states:
فَلَمَّا قَضَىٰ مُوسَى الْأَجَلَ وَسَارَ بِأَهْلِهِ آنَسَ مِنْ جَانِبِ الطُّورِ نَارًا قَالَ لِأَهْلِهِ امْكُثُوا إِنِّي آنَسْتُ نَارًا لَعَلِّي آتِيكُمْ مِنْهَا بِخَبَرٍ أَوْ جَذْوَةٍ مِنَ النَّارِ لَعَلَّكُمْ تَصْطَلُونَ
“When Moses completed the term and travelled with his family, he noticed a fire on the side of the mountain. He said to his family: Stay here; I have seen a fire. Perhaps I will bring you news from it, or an ember from the fire, so that you may warm yourselves.”
Al-Qaṣaṣ 28:29
تَصْطَلُونَ is Form VIII; its ṭāʾ replaces the form’s tāʾ after ṣād. In both verses, the fire from which Moses brings an ember provides warmth for his family.
These two verses prevent a fundamental mistake: Ṣ L Y is not intrinsically about punishment.
They convey a need for warmth but do not identify the season. “A cold winter night” adds details that these expressions do not provide.
Nor should we invent an absolute opposition in which iṣṭilāʾ always denotes gentle, controlled warmth and ṣaliya always denotes intense fire. Taṣṭalūna is Form VIII and expresses warming oneself at a fire; the Qur’anic Form I uses chiefly concern punishment. That is a real difference in usage, but not a physical law governing heat intensity.
Why “burn” is not always a complete equivalent
Burn is a natural English rendering in many of these verses, but it can suggest two different things:
Being exposed to fire and harmed by its heat, or burning away until the material is entirely consumed.
Ṣ L Y does not require the second interpretation.
Al-Ṭūr 52:16, al-Aʿlā 87:12, 87:13 and al-Nisāʾ 4:56 all describe a person remaining exposed to fire in a context of punishment.
“Burn” can therefore be a valid translation, provided it is not understood to mean “be completely destroyed and cease to exist.”
“Entering the fire and enduring its heat” makes this aspect of the usage clearer.
Ṣ L Y and Ḥ R Q: overlapping fields without an absolute boundary
Ṣaliya and ḥaraqa can both concern fire and burning, but their emphasis is not always identical.
Ṣaliya foregrounds the person’s relation to fire and heat: يَصْلَى النَّارَ describes exposure to a burning fire, while تَصْطَلُونَ concerns fire used for warmth.
Ḥ R Q also concerns burning or causing something to burn, but it should not be defined as “necessarily reducing to ashes.” The root does not require that outcome.
In al-Anbiyāʾ 21:68, حَرِّقُوهُ is a command to burn Abraham; the following verse speaks of the fire becoming cool and safe for him. Thus the command alone does not guarantee that burning or reduction to ashes actually occurs.
A more secure distinction is:
Ṣ L Y prominently expresses exposure to fire and receiving or enduring its heat; Ḥ R Q places greater emphasis on burning itself or causing something to burn.
The two fields can overlap in particular cases.
Ṣ L Y and Salat: similarity of form is insufficient
In the Qur’an, صَلُّوهُ in al-Ḥāqqah 69:31 accompanies al-jaḥīm, whereas صَلِّ عَلَيْهِمْ in al-Tawbah 9:103 occurs in a sentence about ṣalātaka. Similarity in part of the word’s form does not give these two contexts the same meaning.
Meaning must be examined through the words accompanying each occurrence and the sentence containing it.
The modern Qur’anic morphological concordance groups the fire usages under ص ل ي and the ṣalāh/ṣalawāt family under ص ل و.
Formal similarity alone cannot establish that Salat originally meant burning, or that ṣaliya al-nāra derives from Salat.
The more cautious conclusion is therefore:
The Qur’anic fire usages and the Qur’anic Salat usages should be studied separately in terms of meaning. Establishing or excluding a more distant historical connection requires independent linguistic research; resemblance alone cannot settle it.
Translation choices
For يَصْلَى النار / يَصْلَوْنَهَا, “enters the fire,” “burns in it” or, depending on the sentence, “endures its heat” may work. The translation should be natural without imposing immediate destruction on the root.
For اصْلَوْهَا in al-Ṭūr 52:16, “Enter it” or “Endure its heat” fits the continuation فاصبروا أو لا تصبروا.
For نُصْلِيهِ / نُصْلِيهِمْ, “We will consign him to the fire,” “We will place them in a fire” or “We will expose them to fire” preserves the causative distinction.
For صَلُّوهُ, “Consign him to the blazing fire” or “Make him enter the blazing fire” is natural.
For تَصْلِيَةُ جَحِيمٍ, “being consigned to the blazing fire” better preserves the causative aspect of the verbal noun; “entering the blazing fire” expresses its outcome.
For تَصْطَلُونَ, “warm yourselves” is clear and natural.
صِلِيًّا occurs in Maryam 19:70 in هُمْ أَوْلَىٰ بِهَا صِلِيًّا, concerning burning or entering the fire, rather than naming the fire itself. صَالِ الْجَحِيمِ in al-Ṣāffāt 37:163 is a singular active participle; صَالُو النَّارِ in Ṣād 38:59 and لَصَالُو الْجَحِيمِ in al-Muṭaffifīn 83:16 are plural forms. The plural ending’s nūn is dropped in these construct phrases. These forms describe those who are exposed to the fire.
Conclusion
The uses of Ṣ L Y share a clear physical image: exposure to fire and its heat.
The reading of Safaitic SIJ 293 records a causative form of the family for making a burnt offering. In al-Muraqqish al-Aṣghar’s poem, taṣṭalī al-nāra concerns warming oneself at a fire. Both provide evidence of the connection with fire outside Qur’anic punishment contexts; neither establishes a precise date for the inscription or the chronological development of all the meanings.
The Qur’an retains this field. In Form I يَصْلَى, the person experiences the fire. In Forms IV and II, another agent places them in it. صِلِيّ, صَالٍ and تَصْلِيَة belong to the same network.
Al-Ṭūr 52:16, al-Aʿlā 87:12, 87:13 and al-Nisāʾ 4:56 show why ṣaliya should not mean immediate destruction in their punishment contexts: the person is in the fire and experiences its heat. Yet continuation is established by those verses’ contexts; the root alone does not mean “eternal” or “continuous.”
The two occurrences of تَصْطَلُونَ in Moses’ story show another application: fire can supply warmth. That alone excludes punishment from the family’s necessary core meaning.
There is no absolute boundary with Ḥ R Q. Ṣ L Y places greater emphasis on exposure to fire and its heat, and Ḥ R Q on burning or causing something to burn; but Ḥ R Q does not itself mean being reduced to ashes.
The Salat family should not be merged with the fire usages simply because their forms resemble one another. Al-jaḥīm in al-Ḥāqqah and ṣalātaka in al-Tawbah identify different contexts. Any claim about a more distant historical relationship requires independent evidence.
Ṣ L Y: exposure to fire and its heat, whether to receive warmth or endure burning; in causative forms, placing another person in that condition. The family does not invariably require punishment, indefinite duration or complete destruction. The verb’s structure identifies the participants’ roles, while context clarifies the kind and duration of exposure to fire.
