Qur'anic Root Ayn Q L
Tying, restraining, understanding, connecting meaning, and holding judgment back from scattering
1. Introduction to the Root
The root “Ayn Q L” in Arabic points to tying, holding, restraining, and preventing something from becoming loose. From this same field, “عَقَلَ البَعِيرَ” means tying the camel’s leg, “عِقَال” means the cord by which a camel is restrained, and “مَعْقِل” means a refuge, stronghold, or protected place.
This root also came to indicate understanding, grasping, discerning, and retaining the meaning of something. In this usage, the human being does not merely hear speech, see a sign, or witness an event; he connects its parts to one another, grasps the relation between them, detects inconsistencies, and restrains his judgment from scattering and haste.
The major meanings of this root may be recognized in several fields:
- tying and restraining;
- holding back and preventing;
- understanding and grasping;
- retaining speech or meaning;
- refuge and place of protection;
- blood-money in the social usage of early Arabic;
- some rare meanings connected with cloth, patterning, and certain bodily states.
All Qur'anic uses of this root are verbal and relate to understanding, weighing, and setting the power of discernment to work. In the Qur'an, “عَقْل” does not appear as a noun; rather, the act of reasoning is expressed through verbs.
2. The Basic Material Image
The most tangible image of this root in early Arabian life is tying the leg of a camel:
“عَقَلَ البَعِيرَ”
That is, he tied the camel’s leg with a cord so it could not freely wander away. The cord used for this was called “عِقَال”.
This tying did not mean destroying the camel’s power of movement. The camel remained alive and capable of moving, but its movement was taken out of a loose, unbounded state and held within a limit. In the desert, an animal left loose could wander off and be lost; the iqāl prevented such unrestrained movement.
From this same image one can see the semantic relation between “tying” and “understanding.” Reason does not stop thought; it prevents thought from scattering and wandering. Things heard, seen, experienced, and followed by consequences are tied to one another so that a coherent meaning may be reached.
Even so, the Qur'anic use of this root should not be translated only as “tying.” The image of tying shows the historical ground of the root, but the meaning of the verb in the Qur'an is clarified by contexts such as understanding speech, grasping a parable, detecting contradiction, weighing evidence, and considering consequences.
3. Semantic Core
The general core of the root “Ayn Q L” may be stated as follows:
Holding and restraining something so that it does not become scattered, loose, or disordered.
In the field of cognition, this core expands in the following way:
Receiving and retaining the meaning of matters, connecting their parts, weighing relations, and restraining judgment from falling into contradiction, haste, and disorder.
Therefore, reasoning in Qur'anic usage is not merely possessing information. A person may hear something, yet not weigh its relation with other matters. He may see an event, yet draw no conclusion from it. He may understand a statement, yet deliberately act against it.
“Reasoning” is an act; an act performed on auditory, visual, historical, linguistic, social, and moral data.
4. Lexical Branches of the Root
4.1. Tying and Restraining
“عَقَلَ” was used for tying the leg of an animal, especially a camel. “عِقَال” was the instrument of this tying. The main element in this usage is preventing loose movement and keeping the animal within a defined limit.
4.2. Holding Back and Preventing
This root was also used for preventing a person from something. “عَقَلَهُ عَنْ كَذَا” means he held him back from that thing.
From this field, reason came to be described as a power that restrains the human being from unexamined speech and behavior. This restraint is the result of understanding and discernment, not mere inability, compulsion, or fear.
4.3. Understanding and Grasping
“عَقَلَ الشَّيْءَ” means he understood that thing and grasped its meaning. In this usage, the verb takes a direct object: a person reasons through a speech, a parable, or a matter.
Understanding here is not merely hearing the words; it is retaining their meaning and grasping their relation to the subject under discussion.
4.4. Refuge and Place of Protection
“مَعْقِل” is used for a firm place, refuge, or stronghold. Just as a cord keeps an animal within a boundary, a ma'qil keeps the human being away from the reach of danger.
In some lexical reports, “عَقْل” and its plural “عُقُول” are also used for refuges and strongholds.
4.5. Blood-Money
In early Arabic, “عَقْل” was also used for blood-money. Blood-money was often paid in camels, which were brought to the family of the slain person and tied there. From this, the name of tying, or of the tied camels, passed to the blood-money itself.
“عَاقِلَة” in legal usage came to mean the relatives who share in paying the blood-money.
This branch does not appear in the Qur'an.
4.6. Rare Uses
In lexical reports, “عَقْل” is also recorded for a kind of cloth or red pattern. Forms of this root are also reported for certain contractions, diseases of an animal’s leg, bodily restraint, or something being held back.
These rare meanings, though part of the history of the word, do not have a direct role in determining the meaning of Qur'anic uses.
5. Examples from Pre-Islamic Arabic
5.1. Tying the Camel
The phrase “عَقَلَ البَعِيرَ” comes from the language of pastoral and desert life. The camel was tied with an “عِقَال” so that it would not move away from the place. This usage preserves the clear material image of the root:
- the camel has the power to move;
- its movement can become loose;
- the cord keeps its movement within a boundary.
This image provided one of the grounds for the root’s movement into the field of understanding and restraint.
5.2. Refuge in Pre-Islamic Poetry
In a verse attributed to Uhayhah ibn al-Julāh, a pre-Islamic poet, it is said:
“وَقَدْ أَعْدَدْتُ لِلْحَدَثَانِ صَعْبًا
لَوْ أَنَّ الْمَرْءَ تَنْفَعُهُ الْعُقُولُ”
The sense of the verse is that he had prepared a difficult and strong refuge for the events of time, if refuges could benefit a person against destiny.
“العُقُول” in this verse does not mean mental intellects; it refers to refuges, strongholds, or means of protection. This usage shows that the concept of holding and preserving was present in the family of this root.
5.3. Blood-Money in Poetry Connected with the Pre-Islamic Period
In verses by Kabshah, the sister of Amr ibn Ma'dīkarib, about an event in the pre-Islamic period, it is said:
“وَأَرْسَلَ عَبْدُ اللَّهِ إِذْ حَانَ يَوْمُهُ
إِلَى قَوْمِهِ لَا تَعْقِلُوا لَهُمْ دَمِي
وَلَا تَأْخُذُوا مِنْهُمْ إِفَالًا وَأَبْكُرًا
وَأُتْرَكْ فِي بَيْتٍ بِصَعْدَةَ مُظْلِمِ”
Here “لَا تَعْقِلُوا لَهُمْ دَمِي” concerns accepting blood-money for the blood of the slain person. The following line, by mentioning young camels, clarifies the material ground of this usage.
This witness shows that “aql” in the social system of the Arabs before Islam could be connected with paying and accepting blood-money.
5.4. The Name of a Kind of Cloth
Alqamah al-Fahl, a pre-Islamic poet, says in describing a colored covering:
“عَقْلًا وَرَقْمًا تَكَادُ الطَّيْرُ تَخْطَفُهُ
كَأَنَّهُ مِنْ دَمِ الْأَجْوَافِ مَدْمُومُ”
“عَقْلًا” in this verse has been understood as the name of a kind of cloth, covering, or red pattern. This is a rare branch and should not be mixed with the meaning of understanding in the Qur'an. Its importance is that it shows outwardly similar words do not always carry the same usage.
6. Important Derivatives
Among the important forms of this family are:
- عَقَلَ يَعْقِلُ: tied, restrained, understood, or grasped.
- عَقْل: tying, restraining, understanding, and the power of discernment; and in another usage, blood-money.
- عَاقِل: one who understands, weighs, or restrains his behavior.
- عُقَلَاء: plural of ʿāqil.
- عَقُول: highly understanding or possessing strong understanding; and in some early uses, plural of refuge.
- عِقَال: camel-cord.
- مَعْقِل: refuge, stronghold, and protected place.
- مَعْقُول: understood, or what reason accepts; and in some early structures, understanding itself.
- اعْتَقَلَ: detained, put in bonds, or took refuge in a protected place.
- تَعَقَّلَ: understood with reflection, considered, or restrained oneself.
- تَعَقُّل: the considered act of understanding and using reason.
Not all these forms appear in the Qur'an. The Qur'an uses from this family only various forms of the simple verb “عَقَلَ يَعْقِلُ”.
7. Qur'anic Forms
Reference Cards for Qur'anic Derivatives
You reason; you bring the faculty of discernment to bear on a sign, speech, or contradiction.
They reason; they grasp relations among signs, proofs, and consequences.
They understood it and grasped the meaning of the speech, though fidelity to it is another step.
He reasons through them; he passes from the outward image of the parable to its inner relation.
We used to reason; an admission that the message should have been heard and weighed.
The root “Ayn Q L” appears in the Qur'an only as the simple verb. Its Qur'anic forms are:
- “تَعْقِلُونَ”;
- “يَعْقِلُونَ”;
- “عَقَلُوهُ”;
- “يَعْقِلُهَا”;
- “نَعْقِلُ”.
The forms “عَقْل”, “عَاقِل”, “عُقَلَاء”, “تَعَقُّل”, and “مَعْقُول” do not appear in the Qur'an.
This linguistic structure focuses the Qur'anic use of the root on an act: people reason or do not reason; they reason through a speech; they reason through parables; or they confess that they did not reason.
From the absence of the noun “عَقْل” in the Qur'an, one should not by itself draw a final philosophical or doctrinal conclusion. But linguistically it is clear that the existing forms turn attention toward the act and process of reasoning.
8. The Morphological Structure of “تَعْقِلُونَ”
“تَعْقِلُونَ” in the Qur'an is a present-tense second-person plural verb from “عَقَلَ يَعْقِلُ”:
You reason, understand, or set your power of discernment to work.
The initial “ت” in this word is the sign of the addressed plural in the present tense. Therefore, the Qur'anic “تَعْقِلُونَ” is not from the form “تَفَعُّل” and not from the verb “تَعَقَّلَ”.
The difference between the two structures is:
- تَعْقِلُونَ: you reason; the simple verb from “عَقَلَ”.
- تَتَعَقَّلُونَ: you deliberate or reflect; from the form tafa'ul.
The second form does not appear in the Qur'an. Therefore, although in English one may render “تَعْقِلُونَ” smoothly as “you reason” or “you reflect,” morphologically it should be known that this is the simple verb, not a derivative from form V.
9. The Qur'anic Meaning of “Reasoning”
Two uses with a direct object have special importance for determining the Qur'anic meaning of the root.
9.1. Understanding Speech
“يَسْمَعُونَ كَلَامَ اللَّهِ ثُمَّ يُحَرِّفُونَهُ مِنْ بَعْدِ مَا عَقَلُوهُ”
>
The structure “عَقَلُوهُ” contains an object pronoun: they reasoned it, or understood it. The pronoun refers to the speech they had heard.
Here “reasoning” clearly indicates understanding and grasping speech. They had not only heard the sound; they had grasped the meaning of the speech. Even so, after understanding it, they distorted it.
This verse clarifies a very important boundary:
Understanding a speech is not the same as remaining faithful to it.
A person may grasp the meaning of something correctly, yet change it for another motive. Therefore, the verb “عَقَلَ” by itself does not guarantee that after understanding, the person will act righteously.
9.2. Grasping Parables
“وَتِلْكَ الْأَمْثَالُ نَضْرِبُهَا لِلنَّاسِ وَمَا يَعْقِلُهَا إِلَّا الْعَالِمُونَ”
>
“يَعْقِلُهَا” means he reasons through them or understands them, and the pronoun refers to the parables.
Understanding a parable is not merely knowing the words or seeing its outward image. The person must grasp the relation between the image of the parable and the intended subject. For this reason, reasoning through a parable includes passing from the visible form to the inner relation among the parts of the parable.
The pairing of “يَعْقِلُهَا” with “الْعَالِمُونَ” also shows that knowledge and reason are connected, but they are not identical. Knowledge provides data and recognition; reason grasps the relation among the data and their indication.
10. Fields of Qur'anic Usage
10.1. Detecting Inconsistency Between Speech and Behavior
“أَتَأْمُرُونَ النَّاسَ بِالْبِرِّ وَتَنْسَوْنَ أَنْفُسَكُمْ وَأَنْتُمْ تَتْلُونَ الْكِتَابَ أَفَلَا تَعْقِلُونَ”
>
In this verse several parts are placed beside one another:
- commanding people to birr;
- forgetting yourselves;
- reciting the Book;
- the question “أَفَلَا تَعْقِلُونَ”.
Reasoning in this context is the ability to recognize inconsistency between what is known, what is said, and what is done. The problem is not merely a lack of information, because the addressees recite the Book. The problem is that they do not place their knowledge and behavior within one coherent act of weighing.
10.2. Recognizing Historical Sequence
“يَا أَهْلَ الْكِتَابِ لِمَ تُحَاجُّونَ فِي إِبْرَاهِيمَ وَمَا أُنْزِلَتِ التَّوْرَاةُ وَالْإِنْجِيلُ إِلَّا مِنْ بَعْدِهِ أَفَلَا تَعْقِلُونَ”
>
Here the argument rests on chronological order. Abraham lived before the Torah and the Gospel were sent down. Reasoning means connecting these temporal data and grasping the inconsistency of the claim with historical sequence.
Thus one function of reason in the Qur'an is weighing a claim against time, sequence, and historical evidence.
10.3. Examining Prior Life and Shared Experience
“فَقَدْ لَبِثْتُ فِيكُمْ عُمُرًا مِنْ قَبْلِهِ أَفَلَا تَعْقِلُونَ”
>
In this context, a known lifetime before the present claim is presented as data for weighing that claim. The addressee should weigh the known past, the character of the speaker, and the message now being presented.
Reasoning here is using historical memory and shared experience to evaluate a claim.
10.4. Connecting Natural Signs
In several verses, phenomena such as the creation of the heavens and the earth, the alternation of night and day, rain, the revival of the earth, the variety of fruits, the movement of winds, and the order of the world are accompanied by phrases such as:
“لَآيَاتٍ لِقَوْمٍ يَعْقِلُونَ”
Merely seeing these phenomena is not reasoning. Reasoning occurs when the human being:
- recognizes order among phenomena;
- weighs the relation of causes and outcomes;
- distinguishes change from stability;
- moves from the visible phenomenon to its indication.
The sign is visible to everyone, but turning observation into argument requires the act of reason.
10.5. Understanding Language and Expression
“إِنَّا أَنْزَلْنَاهُ قُرْآنًا عَرَبِيًّا لَعَلَّكُمْ تَعْقِلُونَ”
>
“إِنَّا جَعَلْنَاهُ قُرْآنًا عَرَبِيًّا لَعَلَّكُمْ تَعْقِلُونَ”
>
A comprehensible language provides the necessary material for receiving the message. When speech is presented in the language of the addressees, the linguistic barrier is reduced; but understanding the words is not the end. The addressee must also grasp the structure of the speech, the relations among its propositions, examples, proofs, and consequences.
Thus “لَعَلَّكُمْ تَعْقِلُونَ” does not refer merely to hearing Arabic; rather, the purpose of making the expression accessible is the possibility of reasoning through its content.
10.6. Weighing Value and Consequence
“وَلَلدَّارُ الْآخِرَةُ خَيْرٌ لِلَّذِينَ يَتَّقُونَ أَفَلَا تَعْقِلُونَ”
>
In this usage, reason is connected with comparison and evaluation. The human being must compare passing benefit with lasting outcome, and near pleasure with a more distant consequence.
Reasoning is not only recognizing an existing reality; weighing the value and outcome of choices is also part of its field of use.
10.7. Moving Beyond Imitation
“أَوَلَوْ كَانَ آبَاؤُهُمْ لَا يَعْقِلُونَ شَيْئًا وَلَا يَهْتَدُونَ”
>
Following predecessors leaves the field of weighing when the correctness of their conduct is not examined. Reasoning in this context does not mean rejecting every statement of predecessors; it means not accepting a claim merely because it is inherited.
Reason examines the relation between following and proof.
10.8. Understanding Social Behavior
“إِنَّ الَّذِينَ يُنَادُونَكَ مِنْ وَرَاءِ الْحُجُرَاتِ أَكْثَرُهُمْ لَا يَعْقِلُونَ”
>
Here the absence of reasoning appears in a social behavior. The addressees should have recognized situation, distance, the sanctity of private space, and the proper manner of communication.
This use shows that reason in the Qur'an is not restricted to theoretical and cosmic discussions; weighing situation and regulating social conduct also belong to it.
10.9. Recognizing Outward Unity and Inner Scattering
“تَحْسَبُهُمْ جَمِيعًا وَقُلُوبُهُمْ شَتَّىٰ ذَٰلِكَ بِأَنَّهُمْ قَوْمٌ لَا يَعْقِلُونَ”
>
Their gathered outward appearance is not the same as their inner scattering. The expression “لَا يَعْقِلُونَ” in this context can indicate their inability to create measured connection, recognize shared interests, and build lasting coherence.
This verse uses the root at the level of collective behavior, but one should not extract from it a complete social theory.
11. The Difference Between Hearing and Reasoning
“وَقَالُوا لَوْ كُنَّا نَسْمَعُ أَوْ نَعْقِلُ مَا كُنَّا فِي أَصْحَابِ السَّعِيرِ”
>
In this verse “نَسْمَعُ” and “نَعْقِلُ” appear beside one another. Hearing is receiving the message; reasoning is examining and understanding its indication.
A sound may reach the ear, yet the message may not be taken seriously. Likewise, a message may be heard and even its literal meaning recognized, yet it may not be connected with realities, consequences, and the person’s own conduct.
Therefore, hearing is one pathway by which data enters; reasoning is the act performed upon the data.
The same distinction appears in another verse:
“أَمْ تَحْسَبُ أَنَّ أَكْثَرَهُمْ يَسْمَعُونَ أَوْ يَعْقِلُونَ”
>
The negation of reason in such verses does not mean the absence of biological structure or natural human capacity. The addressees speak, decide, plan, and argue; but in the matter under discussion, they do not use the power of weighing in a way that grasps relations and consequences.
12. What Does “تَعْقِلُونَ” Ask?
The form “تَعْقِلُونَ” is a direct address to a group of listeners. This address appears in several major structures.
12.1. “أَفَلَا تَعْقِلُونَ”
This structure is not a simple question about the existence or absence of reason. The Qur'an is not asking whether the addressees have the capacity for reason; it questions their cognitive conduct:
Are you not weighing the matter?
Are you not grasping the relation between these things?
Are you not putting your power of discernment to work?
The fa in this structure connects the question to what came before. First a datum, contradiction, sign, or consequence is mentioned; then the addressee is called to reason through that very matter.
12.2. “لَعَلَّكُمْ تَعْقِلُونَ”
In this structure, the signs, rulings, or speech are clarified for the addressee so that the ground of reasoning may be prepared:
“كَذَٰلِكَ يُبَيِّنُ اللَّهُ لَكُمُ الْآيَاتِ لَعَلَّكُمْ تَعْقِلُونَ”
Clear explanation gives the addressee the needed material, but it does not determine his response by compulsion. Explanation is given so that understanding, weighing, and reaching a conclusion become possible.
12.3. “إِنْ كُنْتُمْ تَعْقِلُونَ”
In this structure, receiving the conclusion of a statement is made dependent on using reason:
“رَبُّ الْمَشْرِقِ وَالْمَغْرِبِ وَمَا بَيْنَهُمَا إِنْ كُنْتُمْ تَعْقِلُونَ”
>
That is, if you weigh the parts of this statement together and grasp their indication, the conclusion will become recognizable for you.
13. How Does Reasoning Take Place?
The different uses of this root in the Qur'an do not offer a rigid philosophical step-by-step program. Yet by placing them beside one another, several repeated actions can be recognized.
13.1. Receiving Data
Reasoning does not happen without cognitive material. The human being hears, sees, reads, travels through the earth, knows history, and encounters signs.
The ear, the eye, language, experience, and report are paths for receiving data; but receiving itself is not yet the whole act of reason.
13.2. Understanding and Retaining Meaning
In “عَقَلُوهُ”, the addressees had understood the speech. This stage goes beyond hearing the wording. A person must grasp the structure of the speech, the aim of the sentence, and the relation of its parts, and retain the meaning so that it is not lost in the course of the discussion.
13.3. Connecting Matters
Reason places separate data beside one another:
- speech with behavior;
- claim with history;
- phenomenon with cause and outcome;
- choice with consequence;
- outward appearance with inner reality;
- parable with the intended subject.
Without this connection, a person may know each part separately but fail to grasp the indication of the whole.
13.4. Comparing and Weighing
Reason compares between two or more matters: better and worse, lasting and passing, claim and witness, now and future, outward appearance and reality.
This weighing does not allow one near or attractive part to take possession of the whole field of judgment.
13.5. Detecting Contradiction
The question “أَفَلَا تَعْقِلُونَ” sometimes comes after a contradiction has been stated. Reasoning means that a human being can see inconsistency between two positions or two behaviors and not hold them side by side without examination.
13.6. Attending to Consequence
Reason does not judge only what is present now; it also enters the future outcome of a behavior into the weighing. For this reason, verses about the end of deeds and the superiority of the lasting result are accompanied by questions about reason.
13.7. Restraining Hasty Judgment
The root’s connection with tying and restraining can be seen in this stage. Reason holds judgment back from relying only on imitation, immediate desire, anger, fear, or first appearance.
This restraint does not mean silencing feeling or stopping thought; it means preventing one factor from determining the result without weighing other factors.
13.8. Reaching a Result and Accepting Responsibility
After receiving, connecting, and weighing, the human being reaches a conclusion. Yet acting according to the conclusion is another stage. The verse “مِنْ بَعْدِ مَا عَقَلُوهُ” shows that a person can understand a speech and then knowingly act against what it requires.
In Al-Mulk 67:10, those who face the consequence of their deeds say that if they had listened or reasoned, they would not have been among the companions of the Blaze. This admission connects the failure to reason with choice and its consequence. Reasoning enables the human being to weigh proof and outcome; therefore, how he uses this capacity is connected with his responsibility.
This does not mean that everyone who fails to understand something is automatically held responsible. The verses themselves distinguish between hearing, reasoning, clarification of proof, and the human response.
14. The Heart and Reasoning
“أَفَلَمْ يَسِيرُوا فِي الْأَرْضِ فَتَكُونَ لَهُمْ قُلُوبٌ يَعْقِلُونَ بِهَا أَوْ آذَانٌ يَسْمَعُونَ بِهَا”
>
In this structure, “قُلُوبٌ” is not the subject of “يَعْقِلُونَ”, because the subject of the verb is the plural waw in “يَعْقِلُونَ”. Hearts are introduced through “بِهَا” as the instrument by which reasoning is done, just as ears are introduced through “بِهَا” as the instrument by which hearing is done.
The ba in “بِهَا” indicates instrument or seeking assistance:
- hearts with which they reason;
- ears with which they hear.
This grammatical precision matters, because the verse does not say that hearts reason instead of human beings. Rather, human beings reason with their hearts.
In the language of the Qur'an, the heart is not only the name of a bodily organ in anatomy; it is also connected with inclination, reception, decision, acceptance, denial, and judgment. Connecting reasoning with the heart shows that Qur'anic reason is not merely neutral reception and arrangement of information; the inner orientation of the human being can also affect whether he accepts or refuses the indication of the evidence.
Even so, this verse should not be turned into an anatomical claim about the brain and the heart. The subject of the verse is not locating biological cognitive processes, but expressing the human being’s inner capacity to receive and weigh the message of history and experience.
15. Reasoning and Guidance
“عَقَلَ” and “اهْتَدَى” do not mean the same thing. Al-Baqarah 2:75 shows that understanding a speech may occur while faithfulness to it does not occur.
Several stages must therefore be distinguished:
- hearing the speech;
- understanding its meaning;
- accepting its truth;
- acting according to it.
These stages may come together, but linguistically they are not identical.
Likewise, “لَا يَعْقِلُونَ” should not always be taken as absolute ignorance. A person may be capable in many matters, but in a particular matter:
- fail to connect the evidence;
- fail to see contradiction;
- fail to include consequence in the weighing;
- or leave his judgment under the influence of imitation and desire.
Thus the negation of reason in the Qur'an often concerns the failure of this process in the matter under discussion.
16. Difference from Nearby Roots
16.1. Ayn L M (ʿalima)
“عَلِمَ” indicates knowing and becoming aware. “عَقَلَ” focuses on understanding, connecting, and weighing what has become known.
A human being may have information but not grasp the relation between its parts. Conversely, reasoning without enough data and knowledge may reach a wrong conclusion.
In the verse “وَمَا يَعْقِلُهَا إِلَّا الْعَالِمُونَ”, knowledge and reason are connected, but they are not reduced to one word.
16.2. F K R (fakara)
“فَكَرَ” and “تَفَكَّرَ” indicate setting thought in motion about a subject. “عَقَلَ” highlights more the function by which relations are understood and judgment is restrained.
Thinking may be part of the process of reasoning, but not every movement of the mind necessarily reaches coherent understanding.
16.3. F Q H (faqiha)
“فَقِهَ” indicates precise understanding and penetration into the meaning of speech or a matter. “عَقَلَ”, besides understanding, also includes fields such as detecting contradiction, weighing consequence, and connecting signs.
Both verbs are connected with the heart in the Qur'an, but their uses are not fully identical.
16.4. L B B (lubb)
“لُبّ” is the pure core or inner kernel of a thing, and “أُولُو الْأَلْبَابِ” are possessors of pure inner understanding.
“لُبّ” appears in the Qur'an as a noun and as a description of those who possess it; but “Ayn Q L” appears as a verb and expresses the act of weighing and understanding.
16.5. Dh K R (dhakara)
“ذَكَرَ” indicates remembering, making present, and not forgetting. Reasoning may need remembering earlier data, but it goes beyond that and establishes relations among the data.
17. Historical Development of the Meaning
The meanings of understanding, discernment, and restraint existed in early Arabic. The Qur'an used this word in varied fields: speech, history, nature, ethics, social behavior, and the final outcome of deeds.
In later periods, “aql” became a wide abstract noun and received specialized definitions in philosophy, logic, kalam, jurisprudence, and ethics. Terms such as theoretical reason, practical reason, actualized intellect, and other kinds of intellect belong to later scholarly and philosophical systems and are not the Qur'anic forms of this root.
In today’s language as well, reason is sometimes equated with intelligence, memory, cleverness, brain, knowledge, logic, or ordinary prudence. Each of these concepts may relate to reason, but none of them alone covers the whole Qur'anic field of “Ayn Q L”.
Nor should the modern concept of intelligence measurement be imposed on “لَا يَعْقِلُونَ”. In many of these verses, the issue is not the size of mental ability, but the way understanding is used in relation to sign, proof, contradiction, and consequence.
18. Care in Translation
Translating “تَعْقِلُونَ” as “you have reason” is not precise, because the Arabic form is a verb, not a noun and not a statement of possession.
Suitable translations according to context may include:
- you reason;
- you use reason;
- you set your discernment to work;
- you weigh;
- you grasp;
- you understand the relation between these matters.
“أَفَلَا تَعْقِلُونَ” may be translated as:
“Do you not reason?”
Or, by making the function of the verb clearer:
“Do you not set your discernment to work?”
In some contexts:
“Do you not grasp this relation?”
“لَا يَعْقِلُونَ” may also be translated according to context as:
- they do not reason;
- they do not use their power of discernment;
- they do not grasp the indication of the matter;
- they do not establish a relation between these matters.

19. Conclusion
The root “Ayn Q L” in Arabic begins from the field of tying, holding, and restraining. The “عِقَال” keeps the camel’s leg from loose movement, and the “مَعْقِل” keeps the human being in a protected place. From this field, the root came in cognition to indicate understanding, retaining meaning, connecting data, and restraining judgment.
All Qur'anic uses of this root are verbs. The Qur'an does not use “عَقْل” as the name of a mental object or philosophical term; rather, it shows the human being reasoning or not reasoning.
The combined Qur'anic uses show that reasoning includes these acts:
- receiving data through hearing, seeing, language, and experience;
- understanding and retaining its meaning;
- connecting scattered parts;
- comparing claim with witness;
- detecting contradiction;
- weighing value and consequence;
- and restraining judgment from imitation, haste, and disorder.
Even so, understanding is not the same as accepting and acting. A human being can “عَقَلَ” a speech and then distort it. Therefore, reasoning creates the possibility of discernment, but the human response to that discernment is a separate stage.
The compressed meaning of the Qur'anic form may be stated as follows:
“عَقَلَ”: he grasped the meaning and relation of matters, tied them together in a coherent act of weighing, and restrained his judgment from scattering and looseness.
