The word جهر in the Quran

لَّا يُحِبُّ ٱللَّهُ ٱلْجَهْرَ بِٱلسُّوٓءِ مِنَ ٱلْقَوْلِ إِلَّا مَن ظُلِمَ وَكَانَ ٱللَّهُ سَمِيعًا عَلِيمًا ۝١٤٨

Allāh does not like the public mention of evil except by one who has been wronged. And ever is Allāh Hearing and Knowing.

وَهُوَ ٱللَّهُ فِى ٱلسَّمَٰوَٰتِ وَفِى ٱلْأَرْضِ يَعْلَمُ سِرَّكُمْ وَجَهْرَكُمْ وَيَعْلَمُ مَا تَكْسِبُونَ ۝٣

And He is Allāh, [the only deity] in the heavens and the earth. He knows your secret and what you make public, and He knows that which you earn.

وَٱذْكُر رَّبَّكَ فِى نَفْسِكَ تَضَرُّعًا وَخِيفَةً وَدُونَ ٱلْجَهْرِ مِنَ ٱلْقَوْلِ بِٱلْغُدُوِّ وَٱلْـَٔاصَالِ وَلَا تَكُن مِّنَ ٱلْغَٰفِلِينَ ۝٢٠٥

And remember your Lord within yourself in humility and in fear without being apparent in speech - in the mornings and the evenings. And do not be among the heedless.

سَوَآءٌ مِّنكُم مَّنْ أَسَرَّ ٱلْقَوْلَ وَمَن جَهَرَ بِهِۦ وَمَنْ هُوَ مُسْتَخْفٍۭ بِٱلَّيْلِ وَسَارِبٌۢ بِٱلنَّهَارِ ۝١٠

It is the same [to Him] concerning you whether one conceals [his] speech or publicizes it and whether one is hidden by night or conspicuous [among others] by day.

ضَرَبَ ٱللَّهُ مَثَلًا عَبْدًا مَّمْلُوكًا لَّا يَقْدِرُ عَلَىٰ شَىْءٍ وَمَن رَّزَقْنَٰهُ مِنَّا رِزْقًا حَسَنًا فَهُوَ يُنفِقُ مِنْهُ سِرًّا وَجَهْرًا هَلْ يَسْتَوُۥنَ ٱلْحَمْدُ لِلَّهِ بَلْ أَكْثَرُهُمْ لَا يَعْلَمُونَ ۝٧٥

Allāh presents an example: a slave [who is] owned and unable to do a thing and he to whom We have provided from Us good provision, so he spends from it secretly and publicly. Can they be equal? Praise to Allāh! But most of them do not know.

قُلِ ٱدْعُوا۟ ٱللَّهَ أَوِ ٱدْعُوا۟ ٱلرَّحْمَٰنَ أَيًّا مَّا تَدْعُوا۟ فَلَهُ ٱلْأَسْمَآءُ ٱلْحُسْنَىٰ وَلَا تَجْهَرْ بِصَلَاتِكَ وَلَا تُخَافِتْ بِهَا وَٱبْتَغِ بَيْنَ ذَٰلِكَ سَبِيلًا ۝١١٠

Say, "Call upon Allāh or call upon the Most Merciful [ar-Raḥmān]. Whichever [name] you call - to Him belong the best names." And do not recite [too] loudly in your prayer or [too] quietly but seek between that an [intermediate] way.

وَإِن تَجْهَرْ بِٱلْقَوْلِ فَإِنَّهُۥ يَعْلَمُ ٱلسِّرَّ وَأَخْفَى ۝٧

And if you speak aloud - then indeed, He knows the secret and what is [even] more hidden.

إِنَّهُۥ يَعْلَمُ ٱلْجَهْرَ مِنَ ٱلْقَوْلِ وَيَعْلَمُ مَا تَكْتُمُونَ ۝١١٠

Indeed, He knows what is declared of speech, and He knows what you conceal.

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَرْفَعُوٓا۟ أَصْوَٰتَكُمْ فَوْقَ صَوْتِ ٱلنَّبِىِّ وَلَا تَجْهَرُوا۟ لَهُۥ بِٱلْقَوْلِ كَجَهْرِ بَعْضِكُمْ لِبَعْضٍ أَن تَحْبَطَ أَعْمَٰلُكُمْ وَأَنتُمْ لَا تَشْعُرُونَ ۝٢

O you who have believed, do not raise your voices above the voice of the Prophet or be loud to him in speech like the loudness of some of you to others, lest your deeds become worthless while you perceive not.

وَأَسِرُّوا۟ قَوْلَكُمْ أَوِ ٱجْهَرُوا۟ بِهِۦٓ إِنَّهُۥ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ ۝١٣

And conceal your speech or publicize it; indeed, He is Knowing of that within the breasts.

إِلَّا مَا شَآءَ ٱللَّهُ إِنَّهُۥ يَعْلَمُ ٱلْجَهْرَ وَمَا يَخْفَىٰ ۝٧

Except what Allāh should will. Indeed, He knows what is declared and what is hidden.
