1. 14:34 وَءَاتَىٰكُم مِّن كُلِّ مَا سَأَلْتُمُوهُ وَإِن تَعُدُّوا۟ نِعْمَتَ ٱللَّهِ لَا تُحْصُوهَآ إِنَّ ٱلْإِنسَٰنَ لَظَلُومٌ كَفَّارٌ

   And He gives you of all that you ask Him; and if you count Allah's favors, you will not be able to number them; most surely man is very unjust, very ungrateful.
   

2. 16:18 وَإِن تَعُدُّوا۟ نِعْمَةَ ٱللَّهِ لَا تُحْصُوهَآ إِنَّ ٱللَّهَ لَغَفُورٌ رَّحِيمٌ

   And if you would count Allah's favors, you will not be able to number them; most surely Allah is Forgiving, Merciful.
   

3. 18:12 ثُمَّ بَعَثْنَٰهُمْ لِنَعْلَمَ أَىُّ ٱلْحِزْبَيْنِ أَحْصَىٰ لِمَا لَبِثُوٓا۟ أَمَدًا

   Then We raised them up that We might know which of the two parties was best able to compute the time for which they remained.
   

4. 18:49 وَوُضِعَ ٱلْكِتَٰبُ فَتَرَى ٱلْمُجْرِمِينَ مُشْفِقِينَ مِمَّا فِيهِ وَيَقُولُونَ يَٰوَيْلَتَنَا مَالِ هَٰذَا ٱلْكِتَٰبِ لَا يُغَادِرُ صَغِيرَةً وَلَا كَبِيرَةً إِلَّآ أَحْصَىٰهَا وَوَجَدُوا۟ مَا عَمِلُوا۟ حَاضِرًا وَلَا يَظْلِمُ رَبُّكَ أَحَدًا

   And the Book shall be placed, then you will see the guilty fearing from what is in it, and they will say: Ah! woe to us! what a book is this! it does not omit a small one nor a great one, but numbers them (all); and what they had done they shall find present (there); and your Lord does not deal unjustly with anyone.
   

5. 19:94 لَّقَدْ أَحْصَىٰهُمْ وَعَدَّهُمْ عَدًّا

   Certainly He has a comprehensive knowledge of them and He has numbered them a (comprehensive) numbering.
   

6. 36:12 إِنَّا نَحْنُ نُحْىِ ٱلْمَوْتَىٰ وَنَكْتُبُ مَا قَدَّمُوا۟ وَءَاثَٰرَهُمْ وَكُلَّ شَىْءٍ أَحْصَيْنَٰهُ فِىٓ إِمَامٍ مُّبِينٍ

   Surely We give life to the dead, and We write down what they have sent before and their footprints, and We have recorded everything in a clear writing.
   

7. 58:6 يَوْمَ يَبْعَثُهُمُ ٱللَّهُ جَمِيعًا فَيُنَبِّئُهُم بِمَا عَمِلُوٓا۟ أَحْصَىٰهُ ٱللَّهُ وَنَسُوهُ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ شَهِيدٌ

   On the day when Allah will raise them up all together, then inform them of what they did: Allah has recorded it while they have forgotten it; and Allah is a witness of all things.
   

8. 65:1 يَٰٓأَيُّهَا ٱلنَّبِىُّ إِذَا طَلَّقْتُمُ ٱلنِّسَآءَ فَطَلِّقُوهُنَّ لِعِدَّتِهِنَّ وَأَحْصُوا۟ ٱلْعِدَّةَ وَٱتَّقُوا۟ ٱللَّهَ رَبَّكُمْ لَا تُخْرِجُوهُنَّ مِنۢ بُيُوتِهِنَّ وَلَا يَخْرُجْنَ إِلَّآ أَن يَأْتِينَ بِفَٰحِشَةٍ مُّبَيِّنَةٍ وَتِلْكَ حُدُودُ ٱللَّهِ وَمَن يَتَعَدَّ حُدُودَ ٱللَّهِ فَقَدْ ظَلَمَ نَفْسَهُۥ لَا تَدْرِى لَعَلَّ ٱللَّهَ يُحْدِثُ بَعْدَ ذَٰلِكَ أَمْرًا

   O Prophet! when you divorce women, divorce them for~ their prescribed time, and calculate the number of the days prescribed, and be careful of (your duty to) Allah, your Lord. Do not drive them out of their houses, nor should they themselves go forth, unless they commit an open indecency; and these are the limits of Allah, and whoever goes beyond the limits of Allah, he indeed does injustice to his own soul. You do not know that Allah may after that bring about reunion.
   

9. 72:28 لِّيَعْلَمَ أَن قَدْ أَبْلَغُوا۟ رِسَٰلَٰتِ رَبِّهِمْ وَأَحَاطَ بِمَا لَدَيْهِمْ وَأَحْصَىٰ كُلَّ شَىْءٍ عَدَدًۢا

   So that He may know that they have truly delivered the messages of their Lord, and He encompasses what is with them and He records the number of all things.
   

10. 73:20 إِنَّ رَبَّكَ يَعْلَمُ أَنَّكَ تَقُومُ أَدْنَىٰ مِن ثُلُثَىِ ٱلَّيْلِ وَنِصْفَهُۥ وَثُلُثَهُۥ وَطَآئِفَةٌ مِّنَ ٱلَّذِينَ مَعَكَ وَٱللَّهُ يُقَدِّرُ ٱلَّيْلَ وَٱلنَّهَارَ عَلِمَ أَن لَّن تُحْصُوهُ فَتَابَ عَلَيْكُمْ فَٱقْرَءُوا۟ مَا تَيَسَّرَ مِنَ ٱلْقُرْءَانِ عَلِمَ أَن سَيَكُونُ مِنكُم مَّرْضَىٰ وَءَاخَرُونَ يَضْرِبُونَ فِى ٱلْأَرْضِ يَبْتَغُونَ مِن فَضْلِ ٱللَّهِ وَءَاخَرُونَ يُقَٰتِلُونَ فِى سَبِيلِ ٱللَّهِ فَٱقْرَءُوا۟ مَا تَيَسَّرَ مِنْهُ وَأَقِيمُوا۟ ٱلصَّلَوٰةَ وَءَاتُوا۟ ٱلزَّكَوٰةَ وَأَقْرِضُوا۟ ٱللَّهَ قَرْضًا حَسَنًا وَمَا تُقَدِّمُوا۟ لِأَنفُسِكُم مِّنْ خَيْرٍ تَجِدُوهُ عِندَ ٱللَّهِ هُوَ خَيْرًا وَأَعْظَمَ أَجْرًا وَٱسْتَغْفِرُوا۟ ٱللَّهَ إِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌۢ

    Surely your Lord knows that you pass in prayer nearly two-thirds of the night, and (sometimes) half of it, and (sometimes) a third of it, and (also) a party of those with you; and Allah measures the night and the day. He knows that you are not able to do it, so He has turned to you (mercifully), therefore read what is easy of the Quran. He knows that there must be among you sick, and others who travel in the land seeking of the bounty of Allah, and others who fight in Allah's way, therefore read as much of it as is easy (to you), and keep up prayer and pay the poor-rate and offer to Allah a goodly gift, and whatever of good you send on beforehand for yourselves, you will find it with Allah; that is best and greatest in reward; and ask forgiveness of Allah; surely Allah is Forgiving, Merciful.
    

11. 78:29 وَكُلَّ شَىْءٍ أَحْصَيْنَٰهُ كِتَٰبًا

    And We have recorded everything in a book,
