The Qur’anic Root KH L Ṣ

A concrete image of the root

The Qur’an itself provides one of the clearest images of this root in Al-Naḥl 16:66:

وَإِنَّ لَكُمْ فِي الْأَنْعَامِ لَعِبْرَةً نُسْقِيكُمْ مِمَّا فِي بُطُونِهِ مِنْ بَيْنِ فَرْثٍ وَدَمٍ لَبَنًا خَالِصًا سَائِغًا لِلشَّارِبِينَ

Wa-inna lakum fī l-anʿāmi la-ʿibratan nusqīkum mimmā fī buṭūnihi min bayni farthin wa-damin labanan khāliṣan sāʾighan li-l-shāribīn.

“And in livestock there is a lesson for you: from what is in their bellies, from between digested matter and blood, We give you pure milk to drink, pleasant for those who drink it.”

Here, خَالِصًا has no ethical meaning. The milk is presented as something distinct and unmixed with what is described around it. This usage shows why understanding خ ل ص should not begin with the later notion of “pure intention.” The starting point is separation and freedom from admixture.

This semantic field was also broad in Arabic: something becoming free from admixture, escaping a predicament, withdrawing from a group, and being reserved for someone all belong to this family. Nevertheless, the recording of these meanings in dictionaries should not be turned into a definitive story about the root’s earliest historical image. For this entry, no pre-Qur’anic poetic evidence with sufficiently clear attribution is available to establish the origin of all these branches; it is therefore better to remain within the semantic field that can be demonstrated.

Withdrawing and being set apart

The basic verb of this root has a very clear illustration in the account of Joseph. When his brothers had given up hope of obtaining Benjamin’s release:

فَلَمَّا اسْتَيْأَسُوا مِنْهُ خَلَصُوا نَجِيًّا

Fa-lammā stayʾasū minhu khalaṣū najiyyan.

“Then, when they despaired of him, they withdrew from the others to confer privately.”
Yūsuf 12:80

Here, خَلَصُوا does not mean becoming pure or sincere. They separate themselves from others and form a private group. نَجِيًّا describes the state of that withdrawn group: they have stepped aside to consult and speak privately among themselves.

In Form X, the same principle leads to being reserved for someone. The king says of Joseph:

وَقَالَ الْمَلِكُ ائْتُونِي بِهِ أَسْتَخْلِصْهُ لِنَفْسِي

Wa-qāla l-maliku ʾtūnī bihi astakhliṣhu li-nafsī.

“The king said: Bring him to me, so that I may reserve him for myself.”
Yūsuf 12:54

The phrase لِنَفْسِي makes the direction of the verb clear. Joseph is to be removed from an ordinary position and given a special place with the king. “Choosing” may be the result, but أستخلصه also contains the idea of exclusive designation: I will set him apart and reserve him for myself.

This explains why “being pure” and “being exclusively reserved” are close within this root. Something removed from others’ participation or admixture can remain solely for one person or group.

Khāliṣ and khāliṣah: purity and exclusivity

In Al-Naḥl, the milk is khāliṣ: the admixture in question is absent from it. In other verses, however, the same root expresses exclusivity.

Al-Baqarah 2:94 states:

قُلْ إِنْ كَانَتْ لَكُمُ الدَّارُ الْآخِرَةُ عِنْدَ اللَّهِ خَالِصَةً مِنْ دُونِ النَّاسِ فَتَمَنَّوُا الْمَوْتَ إِنْ كُنْتُمْ صَادِقِينَ

Qul in kānat lakumu d-dāru l-ākhiratu ʿinda llāhi khāliṣatan min dūni n-nāsi fa-tamannawu l-mawta in kuntum ṣādiqīn.

“Say: If the abode of the Hereafter with The God belongs exclusively to you, apart from all other people, then wish for death, if you are truthful.”

Here, خَالِصَةً cannot mean “pure.” The phrase مِنْ دُونِ النَّاسِ indicates exclusivity: is the Hereafter for you alone, and not for other people?

The same direction appears in Al-Aḥzāb 33:50:

خَالِصَةً لَكَ مِنْ دُونِ الْمُؤْمِنِينَ

Khāliṣatan laka min dūni l-muʾminīn.

“Exclusively for you, apart from the other believers.”

In Al-Anʿām 6:139, concerning a rule that those who associated partners with The God had devised for themselves, we read:

مَا فِي بُطُونِ هَٰذِهِ الْأَنْعَامِ خَالِصَةٌ لِذُكُورِنَا وَمُحَرَّمٌ عَلَىٰ أَزْوَاجِنَا

Mā fī buṭūni hādhihi l-anʿāmi khāliṣatun li-dhukūrinā wa-muḥarramun ʿalā azwājinā.

“What is in the bellies of these livestock is reserved for our males and forbidden to our females.”

In all these cases, the connection with the root’s central meaning is clear: the share of others is excluded, and something remains for one group or person.

Thus, “being pure” and “belonging exclusively” are not wholly unrelated meanings. In one, admixture with another substance is excluded; in the other, the participation of others is excluded.

The use of khāliṣah in Ṣād 38:46 has a more complex construction:

إِنَّا أَخْلَصْنَاهُمْ بِخَالِصَةٍ ذِكْرَى الدَّارِ

Innā akhlaṣnāhum bi-khāliṣatin dhikrā d-dār.

“We set them apart through a pure quality: remembrance of the abode [of the Hereafter].”

The construction بِخَالِصَةٍ ذِكْرَى الدَّارِ has received more than one grammatical analysis, and it is better not to claim more certainty than it allows. What is clear for the root is the recurrence of the same family in أخلصناهم and خالصة: they have been set apart through a distinctive quality or orientation. The precise relationship between ذكرى الدار and خالصة must be understood from the grammar and context of the verse, rather than from خ ل ص alone.

Ikhlāṣ of religion: devoting religion entirely to The God

The most significant semantic development of خ ل ص in the Qur’an appears in constructions in which religion is made pure for The God. If ikhlāṣ is restricted to purity of intention and avoidance of ostentation, some Qur’anic uses of this family fall outside that definition.

Al-Zumar 39:2 states:

إِنَّا أَنْزَلْنَا إِلَيْكَ الْكِتَابَ بِالْحَقِّ فَاعْبُدِ اللَّهَ مُخْلِصًا لَهُ الدِّينَ

Innā anzalnā ilayka l-kitāba bi-l-ḥaqqi fa-ʿbudi llāha mukhliṣan lahu d-dīn.

“We have sent down the Book to you in truth; so worship The God, making religion pure for Him.”

And Al-Bayyinah 98:5:

وَمَا أُمِرُوا إِلَّا لِيَعْبُدُوا اللَّهَ مُخْلِصِينَ لَهُ الدِّينَ حُنَفَاءَ

Wa-mā umirū illā li-yaʿbudū llāha mukhliṣīna lahu d-dīna ḥunafāʾ.

“They were commanded only to worship The God, making religion pure for Him, as people of upright orientation…”

The Qur’anic construction matters: مُخْلِصِينَ لَهُ الدِّينَ. What is made pure is “religion,” and its orientation is “for Him.” Mukhliṣ should therefore not be replaced simply by the inward state “sincere.” The person separates religion from attachment to partners and other objects of worship and devotes it entirely to The God.

This becomes clearer in the verses about danger at sea, including Al-ʿAnkabūt 29:65:

دَعَوُا اللَّهَ مُخْلِصِينَ لَهُ الدِّينَ

Daʿawu llāha mukhliṣīna lahu d-dīn.

When danger removes all other supports, they call upon The God, making religion pure for Him. After their deliverance, however, the Qur’an speaks of a return to associating partners. The contrast between exclusive devotion and association clarifies the semantic field: the issue is not merely a sincere feeling, but the removal of partners and competing orientations.

For this reason, “they called upon The God sincerely” is insufficient on its own. It may express one effect of their state, but it loses the construction له الدين, “religion for Him.”

Al-dīn al-khāliṣ in Al-Zumar 39:3 belongs to the same context:

أَلَا لِلَّهِ الدِّينُ الْخَالِصُ

A-lā li-llāhi d-dīnu l-khāliṣ.

“Be aware: pure religion belongs to The God.”

Purity here should not be understood merely as “pure intention.” Religion that belongs to The God is separated from partners and competing attachments.

Mukhliṣ and mukhlaṣ: two different directions of the action

The distinction between مُخْلِص and مُخْلَص is fundamental to understanding this root.

Mukhliṣ is the active participle of Form IV: someone who makes something pure. In the expression مخلصين له الدين, the person makes religion pure for The God.

Mukhlaṣ, however, is the passive participle: someone who has been made pure. In the reading transmitted by Ḥafṣ, Joseph is described as follows:

إِنَّهُ مِنْ عِبَادِنَا الْمُخْلَصِينَ

Innahu min ʿibādinā l-mukhlaṣīn.

“He is among Our servants who have been made pure.”
Yūsuf 12:24

And of Moses:

إِنَّهُ كَانَ مُخْلَصًا وَكَانَ رَسُولًا نَبِيًّا

Innahu kāna mukhlaṣan wa-kāna rasūlan nabiyyan.

“He had been made pure, and he was a messenger and a prophet.”
Maryam 19:51

In this construction, the person is not the agent who makes something pure; being made pure is what happens to him. “Chosen” may be a natural rendering of the resulting state in some contexts, but the basic meaning should not be reduced to “choosing.” The person is separated from others or from the admixture in question and made pure for a particular purpose.

At some places in the Qur’an, recognized readings differ between mukhliṣ and mukhlaṣ. This shows that the vowel on the lām is not merely a difference in pronunciation: it changes the direction of the action. In one reading, the servant is the one who makes something pure; in the other, he is made pure. This difference must be considered individually in every verse used as evidence.

Nor should concepts that the word does not convey on its own be extracted from mukhlaṣ. Being made pure does not, by itself, mean absolute freedom from error, infallibility, or any later theological theory. If a verse establishes some further quality, that must be derived from its context.

Restricting the meaning to “pure intention”

In later ethical and religious language, ikhlāṣ is often contrasted with riyāʾ, ostentation. This usage is semantically understandable: when an action is separated from the motive of attracting other people’s attention and praise, it can be described as being made pure for The God.

The problem arises when this later branch becomes the definition of the entire root.

The Qur’an speaks of khāliṣ milk; Joseph’s brothers khalaṣū, withdrawing from others; the king wishes to astakhliṣ Joseph for himself; something may be khāliṣah for a person or group; servants may be mukhliṣ or mukhlaṣ; and religion may be made pure for The God.

“Pure intention” cannot explain this entire range.

It is better to relate Qur’anic ikhlāṣ to the broader core of the root: separating something from what is mixed with it or shares in it, so that it remains whole and without a competing partner. Purity of intention is one intelligible application of this principle, rather than the definition of the whole of خ ل ص.

Comparison with related roots

Ṣ F W (ṣafw): purity and choosing

خ ل ص overlaps with ص ف و in purity and choosing, but they are not identical. In the Qur’an, iṣṭifāʾ generally emphasizes selection and choosing. In استخلصه لنفسي, too, the result may be choosing, but the image of خ ل ص places greater emphasis on separating a person from others and reserving him for one party.

This is a tendency, not an absolute rule governing every Arabic usage.

KH Ṣ Ṣ (khuṣūṣ): making something exclusive

خ ص ص directly concerns exclusivity and being specially designated. In forms such as خالصة لك, خ ل ص reaches a very similar result, but its semantic path can be understood through the exclusion of partners and admixture.

In خالصة لك من دون المؤمنين, both directions are visible: something becomes exclusive to one person because others are excluded from that share.

Translation proposals for Forqan

In a material usage such as milk, خَالِص may be translated as “pure,” “unmixed,” or “purified,” depending on the sentence.

For الدين الخالص, “pure religion” is suitable, provided the explanation makes clear that purity is not merely a psychological quality or intention: exclusion of partners and admixture is also present.

In constructions such as خالصة لك and خالصة من دون الناس, خَالِصَة is better translated as “exclusive,” “solely for,” or “reserved for.” “Pure” changes the meaning of the sentence in such verses.

خَلَصُوا نَجِيًّا may be rendered “they withdrew from the others to confer privately.”

أَسْتَخْلِصْهُ لِنَفْسِي may be translated as “I may reserve him for myself.” “I may choose him for myself” also expresses the result, but conveys the image of exclusive designation less clearly.

مُخْلِصِينَ لَهُ الدِّينَ is better understood as “making religion pure for Him,” or, more idiomatically, “devoting religion entirely to Him.” “Sincerely” alone is insufficient.

Depending on context, مُخْلَص may be translated as “made pure,” “set apart,” or, where the result of selection is prominent, “chosen.” It must not, however, be equated with مُخْلِص.

Summary

خ ل ص proceeds from a clear semantic field in the Qur’an: something is separated from admixture, shared participation, or a competing attachment, and remains as itself or for a particular purpose.

Its various branches can be understood from this center. Milk is khāliṣ because it is presented unmixed. Joseph’s brothers khalaṣū because they withdraw from others. Joseph becomes mustakhlaṣ for the king because he is reserved for him. Something is khāliṣah when the participation of others in it is excluded. A person is mukhliṣ when he separates religion from partners for The God, whereas mukhlaṣ, with a fatḥah on the lām, is someone who has himself been made pure for a particular purpose.

Restricting خ ل ص to “sincerity” or “pure intention” therefore makes its Qur’anic field too narrow. These concepts may be among the effects of purity, but they are not the definition of the root.

Concise definition: خ ل ص denotes becoming separated, or separating something, from admixture, shared participation, or a competing attachment. From this center arise the meanings of becoming pure and unmixed, withdrawing from a group, being set apart and exclusively reserved, being chosen, and devoting religion entirely to The God.
