1. 6:110 وَنُقَلِّبُ أَفْـِٔدَتَهُمْ وَأَبْصَٰرَهُمْ كَمَا لَمْ يُؤْمِنُوا۟ بِهِۦٓ أَوَّلَ مَرَّةٍ وَنَذَرُهُمْ فِى طُغْيَٰنِهِمْ يَعْمَهُونَ

   And We will turn their hearts and their sights, even as they did not believe in it the first time, and We will leave them in their inordinacy, blindly wandering on.
   

2. 6:113 وَلِتَصْغَىٰٓ إِلَيْهِ أَفْـِٔدَةُ ٱلَّذِينَ لَا يُؤْمِنُونَ بِٱلْءَاخِرَةِ وَلِيَرْضَوْهُ وَلِيَقْتَرِفُوا۟ مَا هُم مُّقْتَرِفُونَ

   And that the hearts of those who do not believe in the hereafter may incline to it and that they may be well pleased with it and that they may earn what they are going to earn (of evil).
   

3. 11:120 وَكُلًّا نَّقُصُّ عَلَيْكَ مِنْ أَنۢبَآءِ ٱلرُّسُلِ مَا نُثَبِّتُ بِهِۦ فُؤَادَكَ وَجَآءَكَ فِى هَٰذِهِ ٱلْحَقُّ وَمَوْعِظَةٌ وَذِكْرَىٰ لِلْمُؤْمِنِينَ

   And all we relate to you of the accounts of the messengers is to strengthen your heart therewith; and in this has come to you the truth and an admonition, and a reminder to the believers.
   

4. 14:37 رَّبَّنَآ إِنِّىٓ أَسْكَنتُ مِن ذُرِّيَّتِى بِوَادٍ غَيْرِ ذِى زَرْعٍ عِندَ بَيْتِكَ ٱلْمُحَرَّمِ رَبَّنَا لِيُقِيمُوا۟ ٱلصَّلَوٰةَ فَٱجْعَلْ أَفْـِٔدَةً مِّنَ ٱلنَّاسِ تَهْوِىٓ إِلَيْهِمْ وَٱرْزُقْهُم مِّنَ ٱلثَّمَرَٰتِ لَعَلَّهُمْ يَشْكُرُونَ

   O our Lord! surely I have settled a part of my offspring in a valley unproductive of fruit near Thy Sacred House, our Lord! that they may keep up prayer; therefore make the hearts of some people yearn towards them and provide them with fruits; haply they may be grateful:
   

5. 14:43 مُهْطِعِينَ مُقْنِعِى رُءُوسِهِمْ لَا يَرْتَدُّ إِلَيْهِمْ طَرْفُهُمْ وَأَفْـِٔدَتُهُمْ هَوَآءٌ

   Hastening forward, their heads upraised, their eyes not reverting to them and their hearts vacant.
   

6. 16:78 وَٱللَّهُ أَخْرَجَكُم مِّنۢ بُطُونِ أُمَّهَٰتِكُمْ لَا تَعْلَمُونَ شَيْـًٔا وَجَعَلَ لَكُمُ ٱلسَّمْعَ وَٱلْأَبْصَٰرَ وَٱلْأَفْـِٔدَةَ لَعَلَّكُمْ تَشْكُرُونَ

   And Allah has brought you forth from the wombs of your mothers-- you did not know anything-- and He gave you hearing and sight and hearts that you may give thanks.
   

7. 17:36 وَلَا تَقْفُ مَا لَيْسَ لَكَ بِهِۦ عِلْمٌ إِنَّ ٱلسَّمْعَ وَٱلْبَصَرَ وَٱلْفُؤَادَ كُلُّ أُو۟لَٰٓئِكَ كَانَ عَنْهُ مَسْـُٔولًا

   And follow not that of which you have not the knowledge; surely the hearing and the sight and the heart, all of these, shall be questioned about that.
   

8. 23:78 وَهُوَ ٱلَّذِىٓ أَنشَأَ لَكُمُ ٱلسَّمْعَ وَٱلْأَبْصَٰرَ وَٱلْأَفْـِٔدَةَ قَلِيلًا مَّا تَشْكُرُونَ

   And He it is Who made for you the ears and the eyes and the hearts; little is it that you give thanks.
   

9. 25:32 وَقَالَ ٱلَّذِينَ كَفَرُوا۟ لَوْلَا نُزِّلَ عَلَيْهِ ٱلْقُرْءَانُ جُمْلَةً وَٰحِدَةً كَذَٰلِكَ لِنُثَبِّتَ بِهِۦ فُؤَادَكَ وَرَتَّلْنَٰهُ تَرْتِيلًا

   And those who disbelieve say: Why has not the Quran been revealed to him all at once? Thus, that We may strengthen your heart by it and We have arranged it well in arranging.
   

10. 28:10 وَأَصْبَحَ فُؤَادُ أُمِّ مُوسَىٰ فَٰرِغًا إِن كَادَتْ لَتُبْدِى بِهِۦ لَوْلَآ أَن رَّبَطْنَا عَلَىٰ قَلْبِهَا لِتَكُونَ مِنَ ٱلْمُؤْمِنِينَ

    And the heart of Musa's mother was free (from anxiety) she would have almost disclosed it had We not strengthened her heart so that she might be of the believers.
    

11. 32:9 ثُمَّ سَوَّىٰهُ وَنَفَخَ فِيهِ مِن رُّوحِهِۦ وَجَعَلَ لَكُمُ ٱلسَّمْعَ وَٱلْأَبْصَٰرَ وَٱلْأَفْـِٔدَةَ قَلِيلًا مَّا تَشْكُرُونَ

    Then He made him complete and breathed into him of His spirit, and made for you the ears and the eyes and the hearts; little is it that you give thanks.
    

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.
    

13. 53:11 مَا كَذَبَ ٱلْفُؤَادُ مَا رَأَىٰٓ

    The heart was not untrue in (making him see) what he saw.
    

14. 67:23 قُلْ هُوَ ٱلَّذِىٓ أَنشَأَكُمْ وَجَعَلَ لَكُمُ ٱلسَّمْعَ وَٱلْأَبْصَٰرَ وَٱلْأَفْـِٔدَةَ قَلِيلًا مَّا تَشْكُرُونَ

    Say: He it is Who brought you into being and made for you the ears and the eyes and the hearts: little is it that you give thanks.
    

15. 104:7 ٱلَّتِى تَطَّلِعُ عَلَى ٱلْأَفْـِٔدَةِ

    Which rises above the hearts.
