1. 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.
   

2. 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.
   

3. 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.
   

4. 31:7 وَإِذَا تُتْلَىٰ عَلَيْهِ ءَايَٰتُنَا وَلَّىٰ مُسْتَكْبِرًا كَأَن لَّمْ يَسْمَعْهَا كَأَنَّ فِىٓ أُذُنَيْهِ وَقْرًا فَبَشِّرْهُ بِعَذَابٍ أَلِيمٍ

   And when Our communications are recited to him, he turns back proudly, as if he had not heard them, as though in his ears were a heaviness, therefore announce to him a painful chastisement.
   

5. 41:5 وَقَالُوا۟ قُلُوبُنَا فِىٓ أَكِنَّةٍ مِّمَّا تَدْعُونَآ إِلَيْهِ وَفِىٓ ءَاذَانِنَا وَقْرٌ وَمِنۢ بَيْنِنَا وَبَيْنِكَ حِجَابٌ فَٱعْمَلْ إِنَّنَا عَٰمِلُونَ

   And they say: Our hearts are under coverings from that to which you call us, and there is a heaviness in our ears, and a veil hangs between us and you, so work, we too are working.
   

6. 41:44 وَلَوْ جَعَلْنَٰهُ قُرْءَانًا أَعْجَمِيًّا لَّقَالُوا۟ لَوْلَا فُصِّلَتْ ءَايَٰتُهُۥٓ ءَا۬عْجَمِىٌّ وَعَرَبِىٌّ قُلْ هُوَ لِلَّذِينَ ءَامَنُوا۟ هُدًى وَشِفَآءٌ وَٱلَّذِينَ لَا يُؤْمِنُونَ فِىٓ ءَاذَانِهِمْ وَقْرٌ وَهُوَ عَلَيْهِمْ عَمًى أُو۟لَٰٓئِكَ يُنَادَوْنَ مِن مَّكَانٍۭ بَعِيدٍ

   And if We had made it a Quran in a foreign tongue, they would certainly have said: Why have not its communications been made clear? What! a foreign (tongue) and an Arabian! Say: It is to those who believe a guidance and a healing; and (as for) those who do not believe, there is a heaviness in their ears and it is obscure to them; these shall be called to from a far-off place.
   

7. 48:9 لِّتُؤْمِنُوا۟ بِٱللَّهِ وَرَسُولِهِۦ وَتُعَزِّرُوهُ وَتُوَقِّرُوهُ وَتُسَبِّحُوهُ بُكْرَةً وَأَصِيلًا

   That you may believe in Allah and His Messenger and may aid him and revere him; and (that) you may declare His glory, morning and evening.
   

8. 51:2 فَٱلْحَٰمِلَٰتِ وِقْرًا

   Then those clouds bearing the load (of minute things in space).
   

9. 71:13 مَّا لَكُمْ لَا تَرْجُونَ لِلَّهِ وَقَارًا

   What is the matter with you that you fear not the greatness of Allah?
