1. 9:34 يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِنَّ كَثِيرًا مِّنَ ٱلْأَحْبَارِ وَٱلرُّهْبَانِ لَيَأْكُلُونَ أَمْوَٰلَ ٱلنَّاسِ بِٱلْبَٰطِلِ وَيَصُدُّونَ عَن سَبِيلِ ٱللَّهِ وَٱلَّذِينَ يَكْنِزُونَ ٱلذَّهَبَ وَٱلْفِضَّةَ وَلَا يُنفِقُونَهَا فِى سَبِيلِ ٱللَّهِ فَبَشِّرْهُم بِعَذَابٍ أَلِيمٍ

   O you who believe! most surely many of the doctors of law and the monks eat away the property of men falsely, and turn (them) from Allah's way; and (as for) those who hoard up gold and silver and do not spend it in Allah's way, announce to them a painful chastisement,
   

2. 9:35 يَوْمَ يُحْمَىٰ عَلَيْهَا فِى نَارِ جَهَنَّمَ فَتُكْوَىٰ بِهَا جِبَاهُهُمْ وَجُنُوبُهُمْ وَظُهُورُهُمْ هَٰذَا مَا كَنَزْتُمْ لِأَنفُسِكُمْ فَذُوقُوا۟ مَا كُنتُمْ تَكْنِزُونَ

   On the day when it shall be heated in the fire of hell, then their foreheads and their sides and their backs shall be branded with it; this is what you hoarded up for yourselves, therefore taste what you hoarded.
   

3. 11:12 فَلَعَلَّكَ تَارِكٌۢ بَعْضَ مَا يُوحَىٰٓ إِلَيْكَ وَضَآئِقٌۢ بِهِۦ صَدْرُكَ أَن يَقُولُوا۟ لَوْلَآ أُنزِلَ عَلَيْهِ كَنزٌ أَوْ جَآءَ مَعَهُۥ مَلَكٌ إِنَّمَآ أَنتَ نَذِيرٌ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ وَكِيلٌ

   Then, it may be that you will give up part of what is revealed to you and your breast will become straitened by it because they say: Why has not a treasure been sent down upon him or an angel come with him? You are only a warner; and Allah is custodian over all things.
   

4. 18:82 وَأَمَّا ٱلْجِدَارُ فَكَانَ لِغُلَٰمَيْنِ يَتِيمَيْنِ فِى ٱلْمَدِينَةِ وَكَانَ تَحْتَهُۥ كَنزٌ لَّهُمَا وَكَانَ أَبُوهُمَا صَٰلِحًا فَأَرَادَ رَبُّكَ أَن يَبْلُغَآ أَشُدَّهُمَا وَيَسْتَخْرِجَا كَنزَهُمَا رَحْمَةً مِّن رَّبِّكَ وَمَا فَعَلْتُهُۥ عَنْ أَمْرِى ذَٰلِكَ تَأْوِيلُ مَا لَمْ تَسْطِع عَّلَيْهِ صَبْرًا

   And as for the wall, it belonged to two orphan boys in the city, and there was beneath it a treasure belonging to them, and their father was a righteous man; so your Lord desired that they should attain their maturity and take out their treasure, a mercy from your Lord, and I did not do it of my own accord. This is the significance of that with which you could not have patience.
   

5. 25:8 أَوْ يُلْقَىٰٓ إِلَيْهِ كَنزٌ أَوْ تَكُونُ لَهُۥ جَنَّةٌ يَأْكُلُ مِنْهَا وَقَالَ ٱلظَّٰلِمُونَ إِن تَتَّبِعُونَ إِلَّا رَجُلًا مَّسْحُورًا

   Or (why is not) a treasure sent down to him, or he is made to have a garden from which he should eat? And the unjust say: You do not follow any but a man deprived of reason.
   

6. 26:58 وَكُنُوزٍ وَمَقَامٍ كَرِيمٍ

   And treasures and goodly dwellings,
   

7. 28:76 إِنَّ قَٰرُونَ كَانَ مِن قَوْمِ مُوسَىٰ فَبَغَىٰ عَلَيْهِمْ وَءَاتَيْنَٰهُ مِنَ ٱلْكُنُوزِ مَآ إِنَّ مَفَاتِحَهُۥ لَتَنُوٓأُ بِٱلْعُصْبَةِ أُو۟لِى ٱلْقُوَّةِ إِذْ قَالَ لَهُۥ قَوْمُهُۥ لَا تَفْرَحْ إِنَّ ٱللَّهَ لَا يُحِبُّ ٱلْفَرِحِينَ

   Surely Qaroun was of the people of Musa, but he rebelled against them, and We had given him of the treasures, so much so that his hoards of wealth would certainly weigh down a company of men possessed of great strength. When his people said to him: Do not exult, surely Allah does not love the exultant;
