1. 4:78 أَيْنَمَا تَكُونُوا۟ يُدْرِككُّمُ ٱلْمَوْتُ وَلَوْ كُنتُمْ فِى بُرُوجٍ مُّشَيَّدَةٍ وَإِن تُصِبْهُمْ حَسَنَةٌ يَقُولُوا۟ هَٰذِهِۦ مِنْ عِندِ ٱللَّهِ وَإِن تُصِبْهُمْ سَيِّئَةٌ يَقُولُوا۟ هَٰذِهِۦ مِنْ عِندِكَ قُلْ كُلٌّ مِّنْ عِندِ ٱللَّهِ فَمَالِ هَٰٓؤُلَآءِ ٱلْقَوْمِ لَا يَكَادُونَ يَفْقَهُونَ حَدِيثًا

   Wherever you are, death will overtake you, though you are in lofty towers, and if a benefit comes to them, they say: This is from Allah; and if a misfortune befalls them, they say: This is from you. Say: All is from Allah, but what is the matter with these people that they do not make approach to understanding what is told (them)?
   

2. 6:25 وَمِنْهُم مَّن يَسْتَمِعُ إِلَيْكَ وَجَعَلْنَا عَلَىٰ قُلُوبِهِمْ أَكِنَّةً أَن يَفْقَهُوهُ وَفِىٓ ءَاذَانِهِمْ وَقْرًا وَإِن يَرَوْا۟ كُلَّ ءَايَةٍ لَّا يُؤْمِنُوا۟ بِهَا حَتَّىٰٓ إِذَا جَآءُوكَ يُجَٰدِلُونَكَ يَقُولُ ٱلَّذِينَ كَفَرُوٓا۟ إِنْ هَٰذَآ إِلَّآ أَسَٰطِيرُ ٱلْأَوَّلِينَ

   And of them is he who hearkens to you, and We have cast veils over their hearts lest they understand it and a heaviness into their ears; and even if they see every sign they will not believe in it; so much so that when they come to you they only dispute with you; those who disbelieve say: This is naught but the stories of the ancients.
   

3. 6:65 قُلْ هُوَ ٱلْقَادِرُ عَلَىٰٓ أَن يَبْعَثَ عَلَيْكُمْ عَذَابًا مِّن فَوْقِكُمْ أَوْ مِن تَحْتِ أَرْجُلِكُمْ أَوْ يَلْبِسَكُمْ شِيَعًا وَيُذِيقَ بَعْضَكُم بَأْسَ بَعْضٍ ٱنظُرْ كَيْفَ نُصَرِّفُ ٱلْءَايَٰتِ لَعَلَّهُمْ يَفْقَهُونَ

   Say: He has the power that He should send on you a chastisement from above you or from beneath your feet, or that He should throw you into confusion, (making you) of different parties; and make some of you taste the fighting of others. See how We repeat the communications that they may understand.
   

4. 6:98 وَهُوَ ٱلَّذِىٓ أَنشَأَكُم مِّن نَّفْسٍ وَٰحِدَةٍ فَمُسْتَقَرٌّ وَمُسْتَوْدَعٌ قَدْ فَصَّلْنَا ٱلْءَايَٰتِ لِقَوْمٍ يَفْقَهُونَ

   And He it is Who has brought you into being from a single soul, then there is (for you) a resting-place and a depository; indeed We have made plain the communications for a people who understand.
   

5. 7:179 وَلَقَدْ ذَرَأْنَا لِجَهَنَّمَ كَثِيرًا مِّنَ ٱلْجِنِّ وَٱلْإِنسِ لَهُمْ قُلُوبٌ لَّا يَفْقَهُونَ بِهَا وَلَهُمْ أَعْيُنٌ لَّا يُبْصِرُونَ بِهَا وَلَهُمْ ءَاذَانٌ لَّا يَسْمَعُونَ بِهَآ أُو۟لَٰٓئِكَ كَٱلْأَنْعَٰمِ بَلْ هُمْ أَضَلُّ أُو۟لَٰٓئِكَ هُمُ ٱلْغَٰفِلُونَ

   And certainly We have created for hell many of the jinn and the men; they have hearts with which they do not understand, and they have eyes with which they do not see, and they have ears with which they do not hear; they are as cattle, nay, they are in worse errors; these are the heedless ones.
   

6. 8:65 يَٰٓأَيُّهَا ٱلنَّبِىُّ حَرِّضِ ٱلْمُؤْمِنِينَ عَلَى ٱلْقِتَالِ إِن يَكُن مِّنكُمْ عِشْرُونَ صَٰبِرُونَ يَغْلِبُوا۟ مِا۟ئَتَيْنِ وَإِن يَكُن مِّنكُم مِّا۟ئَةٌ يَغْلِبُوٓا۟ أَلْفًا مِّنَ ٱلَّذِينَ كَفَرُوا۟ بِأَنَّهُمْ قَوْمٌ لَّا يَفْقَهُونَ

   O Prophet! urge the believers to war; if there are twenty patient ones of you they shall overcome two hundred, and if there are a hundred of you they shall overcome a thousand of those who disbelieve, because they are a people who do not understand.
   

7. 9:81 فَرِحَ ٱلْمُخَلَّفُونَ بِمَقْعَدِهِمْ خِلَٰفَ رَسُولِ ٱللَّهِ وَكَرِهُوٓا۟ أَن يُجَٰهِدُوا۟ بِأَمْوَٰلِهِمْ وَأَنفُسِهِمْ فِى سَبِيلِ ٱللَّهِ وَقَالُوا۟ لَا تَنفِرُوا۟ فِى ٱلْحَرِّ قُلْ نَارُ جَهَنَّمَ أَشَدُّ حَرًّا لَّوْ كَانُوا۟ يَفْقَهُونَ

   Those who were left behind were glad on account of their sitting behind Allah's Messenger and they were averse from striving m Allah's way with their property and their persons, and said: Do not go forth in the heat. Say: The fire of hell is much severe in heat. Would that they understood (it).
   

8. 9:87 رَضُوا۟ بِأَن يَكُونُوا۟ مَعَ ٱلْخَوَالِفِ وَطُبِعَ عَلَىٰ قُلُوبِهِمْ فَهُمْ لَا يَفْقَهُونَ

   They preferred to be with those who remained behind, and a seal is set on their hearts so they do not understand.
   

9. 9:122 وَمَا كَانَ ٱلْمُؤْمِنُونَ لِيَنفِرُوا۟ كَآفَّةً فَلَوْلَا نَفَرَ مِن كُلِّ فِرْقَةٍ مِّنْهُمْ طَآئِفَةٌ لِّيَتَفَقَّهُوا۟ فِى ٱلدِّينِ وَلِيُنذِرُوا۟ قَوْمَهُمْ إِذَا رَجَعُوٓا۟ إِلَيْهِمْ لَعَلَّهُمْ يَحْذَرُونَ

   And it does not beseem the believers that they should go forth all together; why should not then a company from every party from among them go forth that they may apply themselves to obtain understanding in religion, and that they may warn their people when they come back to them that they may be cautious?
   

10. 9:127 وَإِذَا مَآ أُنزِلَتْ سُورَةٌ نَّظَرَ بَعْضُهُمْ إِلَىٰ بَعْضٍ هَلْ يَرَىٰكُم مِّنْ أَحَدٍ ثُمَّ ٱنصَرَفُوا۟ صَرَفَ ٱللَّهُ قُلُوبَهُم بِأَنَّهُمْ قَوْمٌ لَّا يَفْقَهُونَ

    And whenever a chapter is revealed, they cast glances at one another: Does any one see you? Then they turn away: Allah has turned away their hearts because they are a people who do not understand.
    

11. 11:91 قَالُوا۟ يَٰشُعَيْبُ مَا نَفْقَهُ كَثِيرًا مِّمَّا تَقُولُ وَإِنَّا لَنَرَىٰكَ فِينَا ضَعِيفًا وَلَوْلَا رَهْطُكَ لَرَجَمْنَٰكَ وَمَآ أَنتَ عَلَيْنَا بِعَزِيزٍ

    They said: O Shu'aib! we do not understand much of what you say and most surely we see you to be weak among us, and were it not for your family we would surely stone you, and you are not mighty against us.
    

12. 17:44 تُسَبِّحُ لَهُ ٱلسَّمَٰوَٰتُ ٱلسَّبْعُ وَٱلْأَرْضُ وَمَن فِيهِنَّ وَإِن مِّن شَىْءٍ إِلَّا يُسَبِّحُ بِحَمْدِهِۦ وَلَٰكِن لَّا تَفْقَهُونَ تَسْبِيحَهُمْ إِنَّهُۥ كَانَ حَلِيمًا غَفُورًا

    The seven heavens declare His glory and the earth (too), and those who are in them; and there is not a single thing but glorifies Him with His praise, but you do not understand their glorification; surely He is Forbearing, Forgiving.
    

13. 17:46 وَجَعَلْنَا عَلَىٰ قُلُوبِهِمْ أَكِنَّةً أَن يَفْقَهُوهُ وَفِىٓ ءَاذَانِهِمْ وَقْرًا وَإِذَا ذَكَرْتَ رَبَّكَ فِى ٱلْقُرْءَانِ وَحْدَهُۥ وَلَّوْا۟ عَلَىٰٓ أَدْبَٰرِهِمْ نُفُورًا

    And We have placed coverings on their hearts and a heaviness in their ears lest they understand it, and when you mention your Lord alone in the Quran they turn their backs in aversion.
    

14. 18:57 وَمَنْ أَظْلَمُ مِمَّن ذُكِّرَ بِـَٔايَٰتِ رَبِّهِۦ فَأَعْرَضَ عَنْهَا وَنَسِىَ مَا قَدَّمَتْ يَدَاهُ إِنَّا جَعَلْنَا عَلَىٰ قُلُوبِهِمْ أَكِنَّةً أَن يَفْقَهُوهُ وَفِىٓ ءَاذَانِهِمْ وَقْرًا وَإِن تَدْعُهُمْ إِلَى ٱلْهُدَىٰ فَلَن يَهْتَدُوٓا۟ إِذًا أَبَدًا

    And who is more unjust than he who is reminded of the communications of his Lord, then he turns away from them and forgets what his two hands have sent before? Surely We have placed veils over their hearts lest they should understand it and a heaviness in their ears; and if you call them to the guidance, they will not ever follow the right course in that case.
    

15. 18:93 حَتَّىٰٓ إِذَا بَلَغَ بَيْنَ ٱلسَّدَّيْنِ وَجَدَ مِن دُونِهِمَا قَوْمًا لَّا يَكَادُونَ يَفْقَهُونَ قَوْلًا

    Until when he reached (a place) between the two mountains, he found on that side of them a people who could hardly understand a word.
    

16. 20:28 يَفْقَهُوا۟ قَوْلِى

    (That) they may understand my word;
    

17. 48:15 سَيَقُولُ ٱلْمُخَلَّفُونَ إِذَا ٱنطَلَقْتُمْ إِلَىٰ مَغَانِمَ لِتَأْخُذُوهَا ذَرُونَا نَتَّبِعْكُمْ يُرِيدُونَ أَن يُبَدِّلُوا۟ كَلَٰمَ ٱللَّهِ قُل لَّن تَتَّبِعُونَا كَذَٰلِكُمْ قَالَ ٱللَّهُ مِن قَبْلُ فَسَيَقُولُونَ بَلْ تَحْسُدُونَنَا بَلْ كَانُوا۟ لَا يَفْقَهُونَ إِلَّا قَلِيلًا

    Those who are left behind will say when you set forth for the gaining of acquisitions: Allow us (that) we may follow you. They desire to change the world of Allah. Say: By no means shall you follow us; thus did Allah say before. But they will say: Nay! you are jealous of us. Nay! they do not understand but a little.
    

18. 59:13 لَأَنتُمْ أَشَدُّ رَهْبَةً فِى صُدُورِهِم مِّنَ ٱللَّهِ ذَٰلِكَ بِأَنَّهُمْ قَوْمٌ لَّا يَفْقَهُونَ

    You are certainly greater in being feared in their hearts than Allah; that is because they are a people who do not understand
    

19. 63:3 ذَٰلِكَ بِأَنَّهُمْ ءَامَنُوا۟ ثُمَّ كَفَرُوا۟ فَطُبِعَ عَلَىٰ قُلُوبِهِمْ فَهُمْ لَا يَفْقَهُونَ

    That is because they believe, then disbelieve, so a seal is set upon their hearts so that they do not understand.
    

20. 63:7 هُمُ ٱلَّذِينَ يَقُولُونَ لَا تُنفِقُوا۟ عَلَىٰ مَنْ عِندَ رَسُولِ ٱللَّهِ حَتَّىٰ يَنفَضُّوا۟ وَلِلَّهِ خَزَآئِنُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ وَلَٰكِنَّ ٱلْمُنَٰفِقِينَ لَا يَفْقَهُونَ

    They it is who say: Do not spend upon those who are with the Messenger of Allah until they break up. And Allah's are the treasures of the heavens and the earth, but the hypocrites do not understand.
