Qur'anic Root J H R
Being apparent and public; and in speech, raising the voice so that it leaves softness and concealment.
1. Short Introduction to the Root
The root ج ه ر in the Qur'an moves around being apparent, making something public, and raising the voice so that speech leaves the state of concealment or softness and enters the field of hearing and awareness.
In some verses, jahr is directly connected with loudness of voice, such as the prohibition against raising the voice before the Prophet or the prohibition against reciting the salat too loudly. In some verses, it emphasizes public and open visibility, such as spending in secret and in public, Nuh's open call, or The God's knowledge of what people make apparent. In the form جَهْرَةً, something is sought or seen openly, without covering, in an immediate and manifest way.
These uses return to one shared field: something is not covered, soft, or outside public perception; rather, it becomes apparent, public, or expressed in a hearable and prominent voice.
Short meaning:
Being apparent and public, or making something apparent and public; and in speech, raising the voice so that it leaves the state of softness and concealment.
Jahr in itself is neither positive nor negative. A person may do good openly or may make bad speech public; one may remember The God with a balanced voice or exceed the proper measure in speech. The moral judgment comes from the subject, intention, manner, and context of jahr, not from the root alone.
2. Important Forms and Derivatives of the Root
The root ج ه ر occurs sixteen times in the Qur'an in four main forms: the simple verb جَهَرَ, the noun جَهْر, the noun جِهَار, and the form جَهْرَة. Forms such as majhur and tajahur do not occur in the Qur'an and should not be listed among the Qur'anic derivatives in this article.
جَهَرَ، يَجْهَرُ and its inflected forms
This is the simple verb of the root. In the Qur'an it indicates making speech apparent or raising the voice:
جَهَرَ بِهِ
He made it apparent, or expressed it with a raised voice.
لَا تَجْهَرْ
Do not raise it, or do not recite it openly with a loud voice.
لَا تَجْهَرُوا لَهُ بِالْقَوْلِ
Do not raise your voice in speech with him.
اجْهَرُوا بِهِ
Make it apparent, or express it openly and loudly.
جَهْر
This noun can refer, according to context, to loudness of voice, apparent speech, or a public state. In the Qur'an, jahr is set against words such as سرّ, إخفات, كتمان, and ما يخفى.
جِهَار
This form occurs once in the Qur'an, in the speech of Nuh:
ثُمَّ إِنِّي دَعَوْتُهُمْ جِهَارًا
It indicates an open and public call.
جَهْرَة
This form occurs three times in the Qur'an. In the request to see The God, جَهْرَة indicates open, direct, uncovered seeing. In the expression بَغْتَةً أَوْ جَهْرَةً, it is set against sudden arrival and points to something coming openly and visibly.
3. Reference Cards for Qur'anic Derivatives
Making apparent or expressing with a loud voice; bringing speech out of a soft, hidden, or private state.
Apparentness or loudness of voice; a state in which speech or action is not hidden and enters the field of hearing or awareness.
Openly and publicly; in contrast with a hidden or limited call.
Openly, directly, and without covering; so that the seeing or occurrence is not hidden from the observer.
4. The Semantic Core of the Root
The semantic core of ج ه ر can be described as being outside concealment and entering a state of appearance or audibility.
In speech, this appearing is usually connected with raising the voice. Speech said with jahr does not remain only within the person and is not uttered softly or secretly; it reaches a level at which others can hear it.
In behavior or action, jahr means being public. Spending may be سِرًّا, away from public view, and it may be جَهْرًا, done openly before others.
In seeing, جَهْرَةً points to a state in which there is no veil or covering between the viewer and what is sought to be seen.
Therefore, the two main directions of this root are:
appearance as opposed to concealment
and
loudness and audibility as opposed to softness of voice.
These two directions are not separate from one another. Raising the voice is one way of making speech apparent; yet not every apparent thing is related to loud voice. Open spending may be silent, and something seen جَهْرَةً may not be speech at all.
For this reason, jahr should not be restricted to “shouting,” just as it should not be reduced to new concepts such as data transmission, frequency, or message power. Qur'anic usage speaks of apparentness, publicness, and loudness of voice, and the more precise meaning is determined by the context of each verse.
5. The Material Image of the Root
One recorded material image for this root is cleaning a well whose water has been covered by mud or accumulated matter. In Arabic one could say that the well was جَهَرَ or اجْتَهَرَ: what had covered the water was removed so that the water became visible and clear. This use shows well the movement from coveredness into appearance.
Another image is an open, level piece of land with no tree, hill, or obstacle blocking the view. Lexical sources also report جهراء for an open and exposed space.
In the field of voice, the image is also clear: speech leaves the level of whispering and softness and enters the space of being heard by others.
These images help explain the field of the root, but none of them alone should be treated as the final definition of jahr. The Qur'an uses the root in several areas: voice, speech, action, calling, and open seeing. Their common feature is leaving concealment or low audibility and entering a state of appearance.
6. Use of the Root in Early Arabic
In Arabic lexical sources, جَهَرَ الشيءُ means that something became apparent and visible. Likewise, جَهَرَ بالقول means to say openly or to raise the voice. الجهر is connected with publicness, and الجهرة with what is apparent or seen without a veil.
In the same field, the description جهير الصوت was used for someone with a loud and clear voice. Thus the link between jahr and loudness of voice is not a late religious invention; it is rooted in Arabic usage.
This root is also connected with appearance in other uses. A face or stature that appeared large and prominent to the eye could be described with derivatives from this root. A clear and manifest matter was also called أمر مجهر.
Still, not all branches recorded in dictionaries have equal value for understanding Qur'anic usage. The article should focus on the branches directly connected with the verses: becoming apparent, making public, raising the voice, and seeing without a veil.
7. History of Understanding and Semantic Restriction
One common restriction is to translate jahr only as “reciting loudly” or “shouting.” This meaning is correct in some verses, but it does not cover the whole field of the root.
In the verse:
سِرًّا وَجَهْرًا
the subject is not intensity of sound, but hidden and open spending.
In the verse:
حَتَّىٰ نَرَى اللَّهَ جَهْرَةً
the subject is not raising the voice, but requesting an open and unveiled seeing.
In the verse:
يَعْلَمُ سِرَّكُمْ وَجَهْرَكُمْ
jahr is what has left the hidden state and become apparent.
On the other hand, the meaning of jahr is sometimes expanded too far and made into a theory about political transparency, information systems, energy, encryption, or civilizational structure. Such reflections may be discussed separately, but they do not come directly from the root and the verses themselves.
Jahr is not always a sign of truthfulness either. A person may make bad speech public, exceed the limit with a raised voice, or publicize an improper action. Conversely, doing an act secretly may arise from sincerity or from protecting the dignity of others. Therefore, the contrast between jahr and hiddenness should not be turned into an absolute contrast between truthfulness and hypocrisy.
The Qur'an sometimes accepts jahr, sometimes limits it, and sometimes forbids it. This variety shows that jahr is a manner of appearing or expressing, not an independent moral virtue.
8. Methodological Note
In studying this root, several levels must be distinguished:
Direct Meaning
Being apparent, making public, or raising the voice.
Contextual Manifestation
Saying openly, reciting loudly, making an open call, spending openly, or seeing without a veil.
Moral or Social Result
Whether jahr in a given case is right, wrong, useful, harmful, respectful, or transgressive.
For example, from the verse لَا تَجْهَرُوا لَهُ بِالْقَوْلِ one can understand that raising the voice before the Prophet in that context was wrong; but one cannot conclude that every loud voice is wrong in itself.
From لَا يُحِبُّ اللَّهُ الْجَهْرَ بِالسُّوءِ مِنَ الْقَوْلِ, one also cannot conclude that every public statement about a bad matter is forbidden, because the verse itself makes an exception for the one who has been wronged.
Likewise, from أَرِنَا اللَّهَ جَهْرَةً one should not build a theory about the embodiment of The God, the physical capacity of the eye, or the nature of the divine essence. Jahratan describes the quality of their demand: they sought an open and unveiled showing of The God. Judgment about the possibility or nature of such seeing must be drawn from the whole context and other Qur'anic principles.
Terms such as transmission power, frequency, resistance, encryption, data, database, and central processor are not part of the lexical meaning of this root. Using them as base translation erases the boundary between Qur'anic language and modern theorizing.
9. Qur'anic Uses of the Root
Making Speech Apparent as Opposed to Hiding It
The Qur'an says:
سَوَاءٌ مِنْكُمْ مَنْ أَسَرَّ الْقَوْلَ وَمَنْ جَهَرَ بِهِ وَمَنْ هُوَ مُسْتَخْفٍ بِاللَّيْلِ وَسَارِبٌ بِالنَّهَارِ
Equal among you is the one who conceals speech and the one who makes it apparent, and the one hidden by night and moving openly by day.
In this verse, أَسَرَّ الْقَوْلَ is set against جَهَرَ بِهِ. The contrast shows that jahr concerns bringing speech out of a hidden state and expressing it openly.
The verse does not speak about the exact loudness of the voice or the number of listeners. The point is that hidden speech and apparent speech are equal before the knowledge of The God.
Jahr and Ikhfat in Salat
وَلَا تَجْهَرْ بِصَلَاتِكَ وَلَا تُخَافِتْ بِهَا وَابْتَغِ بَيْنَ ذَٰلِكَ سَبِيلًا
Do not recite your salat too loudly, and do not make it too low; seek a way between that.
In this verse, jahr is set against ikhfat. From this contrast it is clear that jahr here relates to raising the voice, while ikhfat relates to lowering it and making it soft.
The verse approves neither complete silence nor a voice that goes beyond proper measure. The command to seek a way between the two shows that jahr has degrees and that every audible voice is not necessarily the forbidden jahr.
“Do not make your salat public” does not sufficiently convey the sound-related meaning of the verse. In this context, “do not recite it too loudly” or “do not raise your voice in salat beyond measure” is more natural.
Jahr in Speech and The God's Knowledge of What Is More Hidden Than Secret
وَإِنْ تَجْهَرْ بِالْقَوْلِ فَإِنَّهُ يَعْلَمُ السِّرَّ وَأَخْفَى
And if you make speech apparent, He knows the secret and what is more hidden.
Here, jahr is compared with secret and what is still more hidden. The verse says that The God's knowledge does not depend on speech becoming apparent; He knows the secret and even what is more hidden.
Jahr in this verse can include both saying openly and saying loudly. But the main point is the levels of The God's knowledge, not an explanation of how sound travels.
Keeping Proper Measure of Voice Before the Prophet
يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَرْفَعُوا أَصْوَاتَكُمْ فَوْقَ صَوْتِ النَّبِيِّ وَلَا تَجْهَرُوا لَهُ بِالْقَوْلِ كَجَهْرِ بَعْضِكُمْ لِبَعْضٍ أَنْ تَحْبَطَ أَعْمَالُكُمْ وَأَنْتُمْ لَا تَشْعُرُونَ
O you who have faith, do not raise your voices above the voice of the Prophet, and do not speak loudly to him as some of you speak loudly to others, lest your works become void while you do not perceive.
The pairing of لَا تَرْفَعُوا أَصْوَاتَكُمْ with لَا تَجْهَرُوا لَهُ بِالْقَوْلِ shows that jahr in this verse concerns loudness of voice and the manner of address.
The phrase كَجَهْرِ بَعْضِكُمْ لِبَعْضٍ points to the ordinary manner in which people speak loudly to one another. The verse asks them not to use that ordinary, careless manner when addressing the Prophet.
This prohibition does not mean that every apparent speech with the Prophet was forbidden; the issue is measure, tone, and the manner of raising the voice.
Speaking Openly or Secretly and Knowledge of What Is Within Chests
وَأَسِرُّوا قَوْلَكُمْ أَوِ اجْهَرُوا بِهِ إِنَّهُ عَلِيمٌ بِذَاتِ الصُّدُورِ
Conceal your speech or make it apparent; He is knowing of what belongs to the chests.
This verse again sets concealing and jahr against one another. A person may hide his speech or utter it openly, but The God's knowledge surrounds what is within the chests before these two levels.
The phrase ذَاتِ الصُّدُورِ points to what is connected with the inner self of the human being. The verse does not make physical hearing of sound necessary for divine knowledge, but it also does not speak of a “data source,” “code,” or “hidden writing in the body.” These expressions should not replace the language of the verse itself.
Nuh's Open Call
ثُمَّ إِنِّي دَعَوْتُهُمْ جِهَارًا
Then I called them openly.
In the next verse:
ثُمَّ إِنِّي أَعْلَنْتُ لَهُمْ وَأَسْرَرْتُ لَهُمْ إِسْرَارًا
Then I made it public to them, and I spoke to them secretly in secret.
The placement of جِهَارًا beside أَعْلَنْتُ and أَسْرَرْتُ shows that Nuh used different ways of calling: open calling, public announcement, and hidden conversation.
Still, jiharan and announcing should not be treated as completely identical without distinction. The repetition of the two expressions may show that his call took place both with open voice and at a public level. Defining the exact boundary between them requires caution; an absolute distinction should not be built from one verse alone.
Spending in Secret and in Public
وَمَنْ رَزَقْنَاهُ مِنَّا رِزْقًا حَسَنًا فَهُوَ يُنْفِقُ مِنْهُ سِرًّا وَجَهْرًا
And one whom We have provided with good provision from Us spends from it secretly and openly.
In this verse, jahr concerns the publicness of the act, not sound. Spending may be done away from people's gaze or may take place openly.
The verse here does not make one of the two intrinsically superior to the other. Both can be forms of spending. The value of the act must be understood from the wider context, the intention, and its manner.
This use is clear evidence that jahr cannot be translated only as “raising the voice.”
Jahr with Bad Speech
لَا يُحِبُّ اللَّهُ الْجَهْرَ بِالسُّوءِ مِنَ الْقَوْلِ إِلَّا مَنْ ظُلِمَ وَكَانَ اللَّهُ سَمِيعًا عَلِيمًا
The God does not love the open uttering of bad speech, except by one who has been wronged; and The God is Hearing, Knowing.
In this verse, الجهر بالسوء من القول concerns making bad speech open and public. The verse generally does not approve it, but it makes an exception for the one who has been wronged.
This exception is important. The Qur'an does not dissolve the right of the wronged person to speak about the wrong that happened to them into the general ruling.
A translation that only says “The God does not love a loud bad voice” is insufficient. The issue is not merely intensity of sound, but making bad speech public.
What Is Apparent from Speech
إِنَّهُ يَعْلَمُ الْجَهْرَ مِنَ الْقَوْلِ وَيَعْلَمُ مَا تَكْتُمُونَ
He knows what is apparent from speech, and He knows what you conceal.
الْجَهْرَ مِنَ الْقَوْلِ is the apparent and public part of speech, and مَا تَكْتُمُونَ is what people cover and keep hidden.
The particle من can specify jahr in relation to speech: that which belongs to speech and is in a state of appearance.
The verse again shows that jahr is a level of the appearance of speech, not the name of a substance, natural force, or transmission system.
Knowing Jahr and What Is Hidden
إِنَّهُ يَعْلَمُ الْجَهْرَ وَمَا يَخْفَىٰ
He knows the apparent and what becomes hidden.
Here jahr is set against ما يخفى. Jahr is whatever is in a state of manifestation and appearance, while the other side is what remains hidden.
This verse does not restrict jahr to speech. The absence of “speech” broadens the phrase: what is apparent and what becomes hidden are both within The God's knowledge.
Still, jahr in this verse is not a name or attribute of The God; it is the object of The God's knowledge. Therefore, creating a section called “derivatives related to divine attributes” for this root is not correct.
Seeing The God Openly
يَا مُوسَىٰ لَنْ نُؤْمِنَ لَكَ حَتَّىٰ نَرَى اللَّهَ جَهْرَةً
O Musa, we will never have faith in you until we see The God openly.
And in another verse:
فَقَالُوا أَرِنَا اللَّهَ جَهْرَةً
They said: Show us The God openly.
In these two verses, جَهْرَة explains the state of seeing or showing: they demanded an unveiled, open, and direct seeing.
“To see The God with a loud voice” is plainly wrong. This use shows that the field of jahr is broader than sound and reaches the lifting of covering in observation.
On the other hand, the word جَهْرَة itself does not explain what the essence of The God is or by what mechanism He would be seen. The verse reports their demand and the divine response. One should not extract a bodily or scientific theory from the adverb جَهْرَة.
The Punishment Coming Openly
قُلْ أَرَأَيْتَكُمْ إِنْ أَتَاكُمْ عَذَابُ اللَّهِ بَغْتَةً أَوْ جَهْرَةً هَلْ يُهْلَكُ إِلَّا الْقَوْمُ الظَّالِمُونَ
Say: Have you considered, if the punishment of The God comes to you suddenly or openly, are any destroyed except the wrongdoing people?
In this verse, جَهْرَة is set against بَغْتَة. Baghtatan indicates sudden and surprising arrival; jahratan indicates an arrival that is open and visible.
This contrast shows that in this context جَهْرَة is about the mode of appearance of the event more than about sound.
10. Examination of Important Derivatives in the Qur'an
جَهَرَ and يَجْهَرُ
The simple verb in the Qur'an is used both for making speech apparent and for raising the voice.
In Ar-Ra'd 13:10:
مَنْ جَهَرَ بِهِ
means the one who makes speech apparent.
In Al-Isra 17:110:
لَا تَجْهَرْ بِصَلَاتِكَ
means do not raise your voice in salat beyond proper measure.
In Al-Hujurat 49:2:
لَا تَجْهَرُوا لَهُ بِالْقَوْلِ
means do not raise your voice when addressing the Prophet as you address one another in ordinary speech.
Therefore, the verb jahr should not be translated with one fixed expression in every verse. “Make apparent,” “say openly,” and “speak loudly” are each usable in the context that fits.
جَهْر
The noun jahr in the Qur'an covers a range from loudness of voice to publicness.
In:
دُونَ الْجَهْرِ مِنَ الْقَوْلِ
it points to a level below loud speech.
In:
سِرًّا وَجَهْرًا
it concerns openness as opposed to secrecy.
In:
يَعْلَمُ الْجَهْرَ وَمَا يَخْفَىٰ
it points to whatever is apparent as opposed to what remains hidden.
This variety shows that jahr has a base meaning, but its translation must depend on the subject of the sentence.
جِهَار
جِهَارًا occurs only once in the Qur'an:
ثُمَّ إِنِّي دَعَوْتُهُمْ جِهَارًا
This form can be translated “openly,” “publicly,” or “with an open call.” Restricting it to “with shouting” has no sufficient basis.
جَهْرَة
جَهْرَة highlights open and unveiled quality.
In the demand of the Children of Israel, it appears with seeing and showing:
نَرَى اللَّهَ جَهْرَةً
أَرِنَا اللَّهَ جَهْرَةً
In Al-Anam 6:47, it describes the manner in which punishment comes:
بَغْتَةً أَوْ جَهْرَةً
Thus جَهْرَة is not limited only to visual seeing; in both fields, it emphasizes open occurrence and lack of covering.
11. Grammatical and Structural Notes
جَهَرَ with the particle باء
In Qur'anic usage, the verb jahr often comes with باء:
جَهَرَ بِهِ
تَجْهَرْ بِصَلَاتِكَ
تَجْهَرْ بِالْقَوْلِ
اجْهَرُوا بِهِ
The particle باء links to the verb the thing upon which jahr occurs: with it he made the speech apparent, with the salat he raised his voice, or he expressed it openly.
There is no need to create for this باء a meaning such as carrier, wave, or acoustic covering. Its role in Arabic structure is understood through the connection of the verb with speech or salat.
Jahr Opposed to Concealment
Several verses present a contrast:
أَسَرَّ الْقَوْلَ / جَهَرَ بِهِ
أَسِرُّوا قَوْلَكُمْ / اجْهَرُوا بِهِ
سِرًّا / جَهْرًا
This contrast is one of the clearest evidences for the meaning of apparent as opposed to hidden.
Jahr Opposed to Ikhfat
In Al-Isra 17:110 the contrast is:
لَا تَجْهَرْ / لَا تُخَافِتْ
In this context, both sides of the contrast are related to degrees of voice: neither too loud nor too soft.
This verse shows that lexical contrasts must be read in their own context. Jahr is not always opposed to sirr; sometimes it is opposed to ikhfat and its sound-related side becomes prominent.
Jahr Opposed to Khafa' and Kitman
In Al-A'la 87:7:
الْجَهْرَ / مَا يَخْفَىٰ
and in Al-Anbiya 21:110:
الْجَهْرَ مِنَ الْقَوْلِ / مَا تَكْتُمُونَ
appearance is placed opposite becoming hidden or keeping hidden.
جَهْرَة as an Adverbial State
In:
نَرَى اللَّهَ جَهْرَةً
and:
أَرِنَا اللَّهَ جَهْرَةً
the word جَهْرَة explains the state of seeing or showing: openly and without a veil.
In:
أَتَاكُمْ عَذَابُ اللَّهِ بَغْتَةً أَوْ جَهْرَةً
it also describes the manner in which punishment comes.
Therefore, in translation it is better to reflect جَهْرَة as a natural adverb: “openly,” “visibly,” or “without veil,” depending on context.
12. Comparison with Nearby Roots
ج ه ر compared with خ ف ي
The root خ ف ي is connected with being hidden and remaining outside perception. In contrast, ج ه ر points to an apparent and non-hidden state.
This contrast is clear in:
إِنَّهُ يَعْلَمُ الْجَهْرَ وَمَا يَخْفَىٰ
Jahr is what stands in manifestation; khafa' is what is covered and away from appearance.
Still, khafa' is not always the result of deliberate human choice; something may be hidden by nature or by circumstance. Jahr also is not always the result of an effort to raise the voice; an event may itself occur openly.
ج ه ر compared with س ر ر
The root س ر ر, in some Qur'anic structures, concerns keeping speech hidden or doing an action away from public appearance.
In:
مَنْ أَسَرَّ الْقَوْلَ وَمَنْ جَهَرَ بِهِ
israr is an action: the person hides the speech. Jahr is the opposite action: he makes it apparent.
In:
سِرًّا وَجَهْرًا
two modes of doing the act are expressed: in secret and in public.
Thus sirr is one of the closest Qur'anic opposites of jahr, but the root س ر ر has a wider field and not all its derivatives should be reduced to “hidden.”
ج ه ر compared with ع ل ن
The root ع ل ن is also related to publicness and appearance. In Surah Nuh, two close expressions occur:
دَعَوْتُهُمْ جِهَارًا
and:
أَعْلَنْتُ لَهُمْ
This pairing shows that the two roots are close in field, but treating them as completely identical removes necessary caution.
Jahr in many uses has a closer connection with voice and manner of expression; i'lan places more emphasis on bringing something out of concealment and into public awareness. Still, this is a tendency, not an absolute boundary.
One should not say that jahr is necessarily about physical intensity and that i'lan has no relation to voice. The context of each expression decides.
ج ه ر compared with ظ ه ر
The root ظ ه ر has a wider field: appearing, becoming dominant, back, and outer surface. Something that becomes zahir leaves hiddenness, but it is not necessarily connected with sound or speech.
Jahr in the Qur'an is seen especially in the field of speech, voice, call, and publicness of action. Zuhur can be used for the appearing of anything, the manifestation of a result, or becoming dominant.
Thus jahr and zuhur are close in the element of appearance, but jahr in the Qur'anic uses of this root has a more specific link with making speech and action apparent.
ج ه ر compared with ر ف ع in the field of voice
In Al-Hujurat 49:2, two expressions come together:
لَا تَرْفَعُوا أَصْوَاتَكُمْ
and:
لَا تَجْهَرُوا لَهُ بِالْقَوْلِ
Raising the voice directly points to increasing the level of sound. Jahr in speech concerns speaking loudly and openly.
The closeness of the two is clear, but their repetition shows that each has its own angle: one is raising the voice, and the other is the open and loud manner of address.
One should not build an overly rigid distinction from this pairing; both are used in that verse to regulate the manner of speech before the Prophet.
13. Translation Suggestions for Forqan
جَهَرَ بِالْقَوْل
According to context: “said the speech openly,” “spoke with a loud voice,” or “made the speech public.” In sound-related verses, “spoke loudly” is more suitable. In contrast with hidden speech, “said openly” is more precise.
لَا تَجْهَرْ بِصَلَاتِكَ
Suggested: “Do not raise your voice in salat beyond measure.” The translation “do not make your salat public” removes the sound-related side of the contrast with ikhfat.
لَا تَجْهَرُوا لَهُ بِالْقَوْلِ
Suggested: “Do not raise your voice in speech with him.” Or: “Do not speak to him so loudly.”
جَهَرَ بِهِ opposed to أَسَرَّ الْقَوْلَ
Suggested: “He said it openly.” Or: “He expressed it publicly.”
جَهْر
Possible equivalents: apparentness, apparent speech, loudness of voice, public state. One fixed equivalent is not suitable for all verses.
جِهَارًا
Suggested: openly, publicly, with an open call. In Nuh 71:8, “I called them openly” is natural and precise.
جَهْرًا opposed to سِرًّا
Suggested: in secret and in public. In this use, “with a loud voice” is wrong.
جَهْرَةً with seeing
Suggested: openly, visibly, without veil. In the base translation: “until we see The God openly.” The explanation “without a veil between the viewer and what is seen” can appear in the word note, not in the short translation of the verse.
بَغْتَةً أَوْ جَهْرَةً
Suggested: suddenly or openly. Or: unexpectedly or before your view. The first translation is shorter and closer to the structure of the verse.
الْجَهْرَ مِنَ الْقَوْلِ
Suggested: what is apparent from speech; or apparent speech.
الْجَهْرَ وَمَا يَخْفَىٰ
Suggested: the apparent and what becomes hidden. Here jahr should not be translated only as “loud voice,” because the verse sets it without the qualifier of speech against whatever is hidden.
14. Conclusion
The root ج ه ر in the Qur'an moves around being apparent, making public, and raising the voice. Its shared core is leaving concealment or softness and entering a state of manifestation, audibility, or public awareness.
Final suggested definition:
ج ه ر: being apparent and public, or making something apparent and public; and in speech, raising the voice so that it leaves the state of softness and concealment.
Jahr sometimes has a direct link with sound:
لَا تَجْهَرْ بِصَلَاتِكَ
and:
لَا تَجْهَرُوا لَهُ بِالْقَوْلِ
In these verses, the issue is the measure and manner of raising the voice.
Sometimes jahr concerns the publicness of an action:
سِرًّا وَجَهْرًا
Here, spending in secret and in public is compared, and sound intensity is not the issue.
Sometimes jahr describes the quality of seeing or occurrence:
نَرَى اللَّهَ جَهْرَةً
and:
بَغْتَةً أَوْ جَهْرَةً
In these uses, open and unveiled quality is prominent.
Jahr in itself is neither a sign of truth nor a sign of falsehood. True and false speech may both be spoken openly. Hidden and open spending are both possible. The wronged person may make public the bad that happened, while making bad speech public in general is not loved. Therefore, the moral value of jahr comes from context, subject, and direction of the action.
The root ج ه ر stands against خ ف ي and س ر ر in the contrast between apparent and hidden; it comes close to ع ل ن and ظ ه ر in the field of appearance; and in the field of voice it connects with ر ف ع. These differences are tendencies and should not be turned into absolute boundaries.
Terms such as frequency, transmission power, resistance, encryption, data, and information system are not part of the meaning of this root. The Qur'an speaks in natural language about apparent and hidden, loud and soft voice, open calling, public spending, and unveiled seeing.
