1. 6:33 قَدْ نَعْلَمُ إِنَّهُۥ لَيَحْزُنُكَ ٱلَّذِى يَقُولُونَ فَإِنَّهُمْ لَا يُكَذِّبُونَكَ وَلَٰكِنَّ ٱلظَّٰلِمِينَ بِـَٔايَٰتِ ٱللَّهِ يَجْحَدُونَ

   We know indeed that what they say certainly grieves you, but surely they do not call you a liar; but the unjust deny the communications of Allah.
   

2. 7:51 ٱلَّذِينَ ٱتَّخَذُوا۟ دِينَهُمْ لَهْوًا وَلَعِبًا وَغَرَّتْهُمُ ٱلْحَيَوٰةُ ٱلدُّنْيَا فَٱلْيَوْمَ نَنسَىٰهُمْ كَمَا نَسُوا۟ لِقَآءَ يَوْمِهِمْ هَٰذَا وَمَا كَانُوا۟ بِـَٔايَٰتِنَا يَجْحَدُونَ

   Who take their religion for an idle sport and a play and this life's world deceives them; so today We forsake them, as they neglected the meeting of this day of theirs and as they denied Our communications.
   

3. 11:59 وَتِلْكَ عَادٌ جَحَدُوا۟ بِـَٔايَٰتِ رَبِّهِمْ وَعَصَوْا۟ رُسُلَهُۥ وَٱتَّبَعُوٓا۟ أَمْرَ كُلِّ جَبَّارٍ عَنِيدٍ

   And this was Ad; they denied the communications of their Lord, and disobeyed His messengers and followed the bidding of every insolent opposer (of truth).
   

4. 16:71 وَٱللَّهُ فَضَّلَ بَعْضَكُمْ عَلَىٰ بَعْضٍ فِى ٱلرِّزْقِ فَمَا ٱلَّذِينَ فُضِّلُوا۟ بِرَآدِّى رِزْقِهِمْ عَلَىٰ مَا مَلَكَتْ أَيْمَٰنُهُمْ فَهُمْ فِيهِ سَوَآءٌ أَفَبِنِعْمَةِ ٱللَّهِ يَجْحَدُونَ

   And Allah has made some of you excel others in the means of subsistence, so those who are made to excel do not give away their sustenance to those whom their right hands possess so that they should be equal therein; is it then the favor of Allah which they deny?
   

5. 27:14 وَجَحَدُوا۟ بِهَا وَٱسْتَيْقَنَتْهَآ أَنفُسُهُمْ ظُلْمًا وَعُلُوًّا فَٱنظُرْ كَيْفَ كَانَ عَٰقِبَةُ ٱلْمُفْسِدِينَ

   And they denied them unjustly and proudly while their soul had been convinced of them; consider, then how was the end of the mischief-makers.
   

6. 29:47 وَكَذَٰلِكَ أَنزَلْنَآ إِلَيْكَ ٱلْكِتَٰبَ فَٱلَّذِينَ ءَاتَيْنَٰهُمُ ٱلْكِتَٰبَ يُؤْمِنُونَ بِهِۦ وَمِنْ هَٰٓؤُلَآءِ مَن يُؤْمِنُ بِهِۦ وَمَا يَجْحَدُ بِـَٔايَٰتِنَآ إِلَّا ٱلْكَٰفِرُونَ

   And thus have We revealed the Book to you. So those whom We have given the Book believe in it, and of these there are those who believe in it, and none deny Our communications except the unbelievers.
   

7. 29:49 بَلْ هُوَ ءَايَٰتٌۢ بَيِّنَٰتٌ فِى صُدُورِ ٱلَّذِينَ أُوتُوا۟ ٱلْعِلْمَ وَمَا يَجْحَدُ بِـَٔايَٰتِنَآ إِلَّا ٱلظَّٰلِمُونَ

   Nay! these are clear communications in the breasts of those who are granted knowledge; and none deny Our communications except the unjust.
   

8. 31:32 وَإِذَا غَشِيَهُم مَّوْجٌ كَٱلظُّلَلِ دَعَوُا۟ ٱللَّهَ مُخْلِصِينَ لَهُ ٱلدِّينَ فَلَمَّا نَجَّىٰهُمْ إِلَى ٱلْبَرِّ فَمِنْهُم مُّقْتَصِدٌ وَمَا يَجْحَدُ بِـَٔايَٰتِنَآ إِلَّا كُلُّ خَتَّارٍ كَفُورٍ

   And when a wave like mountains covers them they call upon Allah, being sincere to Him in obedience, but when He brings them safe to the land, some of them follow the middle course; and none denies Our signs but every perfidious, ungrateful one.
   

9. 40:63 كَذَٰلِكَ يُؤْفَكُ ٱلَّذِينَ كَانُوا۟ بِـَٔايَٰتِ ٱللَّهِ يَجْحَدُونَ

   Thus were turned away those who denied the communications of Allah.
   

10. 41:15 فَأَمَّا عَادٌ فَٱسْتَكْبَرُوا۟ فِى ٱلْأَرْضِ بِغَيْرِ ٱلْحَقِّ وَقَالُوا۟ مَنْ أَشَدُّ مِنَّا قُوَّةً أَوَلَمْ يَرَوْا۟ أَنَّ ٱللَّهَ ٱلَّذِى خَلَقَهُمْ هُوَ أَشَدُّ مِنْهُمْ قُوَّةً وَكَانُوا۟ بِـَٔايَٰتِنَا يَجْحَدُونَ

    Then as to Ad, they were unjustly proud in the land, and they said: Who is mightier in strength than we? Did they not see that Allah Who created them was mightier than they in strength, and they denied Our communications?
    

11. 41:28 ذَٰلِكَ جَزَآءُ أَعْدَآءِ ٱللَّهِ ٱلنَّارُ لَهُمْ فِيهَا دَارُ ٱلْخُلْدِ جَزَآءًۢ بِمَا كَانُوا۟ بِـَٔايَٰتِنَا يَجْحَدُونَ

    That is the reward of the enemies of Allah-- the fire; for them therein shall be the house of long abiding; a reward for their denying Our communications.
    

12. 46:26 وَلَقَدْ مَكَّنَّٰهُمْ فِيمَآ إِن مَّكَّنَّٰكُمْ فِيهِ وَجَعَلْنَا لَهُمْ سَمْعًا وَأَبْصَٰرًا وَأَفْـِٔدَةً فَمَآ أَغْنَىٰ عَنْهُمْ سَمْعُهُمْ وَلَآ أَبْصَٰرُهُمْ وَلَآ أَفْـِٔدَتُهُم مِّن شَىْءٍ إِذْ كَانُوا۟ يَجْحَدُونَ بِـَٔايَٰتِ ٱللَّهِ وَحَاقَ بِهِم مَّا كَانُوا۟ بِهِۦ يَسْتَهْزِءُونَ

    And certainly We had established them in what We have not established you in, and We had given-- them ears and eyes and hearts, but neither their ears, nor their eyes, nor their hearts availed them aught, since they denied the communications of Allah, and that which they mocked encompassed them.
