1. 6:152 وَلَا تَقْرَبُوا۟ مَالَ ٱلْيَتِيمِ إِلَّا بِٱلَّتِى هِىَ أَحْسَنُ حَتَّىٰ يَبْلُغَ أَشُدَّهُۥ وَأَوْفُوا۟ ٱلْكَيْلَ وَٱلْمِيزَانَ بِٱلْقِسْطِ لَا نُكَلِّفُ نَفْسًا إِلَّا وُسْعَهَا وَإِذَا قُلْتُمْ فَٱعْدِلُوا۟ وَلَوْ كَانَ ذَا قُرْبَىٰ وَبِعَهْدِ ٱللَّهِ أَوْفُوا۟ ذَٰلِكُمْ وَصَّىٰكُم بِهِۦ لَعَلَّكُمْ تَذَكَّرُونَ

   And do not approach the property of the orphan except in the best manner until he attains his maturity, and give full measure and weight with justice-- We do not impose on any soul a duty except to the extent of its ability; and when you speak, then be just though it be (against) a relative, and fulfill Allah's covenant; this He has enjoined you with that you may be mindful;
   

2. 7:8 وَٱلْوَزْنُ يَوْمَئِذٍ ٱلْحَقُّ فَمَن ثَقُلَتْ مَوَٰزِينُهُۥ فَأُو۟لَٰٓئِكَ هُمُ ٱلْمُفْلِحُونَ

   And the measuring out on that day will be just; then as for him whose measure (of good deeds) is heavy, those are they who shall be successful;
   

3. 7:9 وَمَنْ خَفَّتْ مَوَٰزِينُهُۥ فَأُو۟لَٰٓئِكَ ٱلَّذِينَ خَسِرُوٓا۟ أَنفُسَهُم بِمَا كَانُوا۟ بِـَٔايَٰتِنَا يَظْلِمُونَ

   And as for him whose measure (of good deeds) is light those are they who have made their souls suffer loss because they disbelieved in Our communications.
   

4. 7:85 وَإِلَىٰ مَدْيَنَ أَخَاهُمْ شُعَيْبًا قَالَ يَٰقَوْمِ ٱعْبُدُوا۟ ٱللَّهَ مَا لَكُم مِّنْ إِلَٰهٍ غَيْرُهُۥ قَدْ جَآءَتْكُم بَيِّنَةٌ مِّن رَّبِّكُمْ فَأَوْفُوا۟ ٱلْكَيْلَ وَٱلْمِيزَانَ وَلَا تَبْخَسُوا۟ ٱلنَّاسَ أَشْيَآءَهُمْ وَلَا تُفْسِدُوا۟ فِى ٱلْأَرْضِ بَعْدَ إِصْلَٰحِهَا ذَٰلِكُمْ خَيْرٌ لَّكُمْ إِن كُنتُم مُّؤْمِنِينَ

   And to Madyan (We sent) their brother Shu'aib. He said: O my people! serve Allah, you have no god other than Him; clear proof indeed has come to you from your Lord, therefore give full measure and weight and do not diminish to men their things, and do not make mischief in the land after its reform; this is better for you if you are believers:
   

5. 11:84 وَإِلَىٰ مَدْيَنَ أَخَاهُمْ شُعَيْبًا قَالَ يَٰقَوْمِ ٱعْبُدُوا۟ ٱللَّهَ مَا لَكُم مِّنْ إِلَٰهٍ غَيْرُهُۥ وَلَا تَنقُصُوا۟ ٱلْمِكْيَالَ وَٱلْمِيزَانَ إِنِّىٓ أَرَىٰكُم بِخَيْرٍ وَإِنِّىٓ أَخَافُ عَلَيْكُمْ عَذَابَ يَوْمٍ مُّحِيطٍ

   And to Madyan (We sent) their brother Shu'aib. He said: O my people! serve Allah, you have no god other than He, and do not give short measure and weight: surely I see you in prosperity and surely I fear for you the punishment of an all-encompassing day.
   

6. 11:85 وَيَٰقَوْمِ أَوْفُوا۟ ٱلْمِكْيَالَ وَٱلْمِيزَانَ بِٱلْقِسْطِ وَلَا تَبْخَسُوا۟ ٱلنَّاسَ أَشْيَآءَهُمْ وَلَا تَعْثَوْا۟ فِى ٱلْأَرْضِ مُفْسِدِينَ

   And, O my people! give full measure and weight fairly, and defraud not men their things, and do not act corruptly in the land, making mischief:
   

7. 15:19 وَٱلْأَرْضَ مَدَدْنَٰهَا وَأَلْقَيْنَا فِيهَا رَوَٰسِىَ وَأَنۢبَتْنَا فِيهَا مِن كُلِّ شَىْءٍ مَّوْزُونٍ

   And the earth-- We have spread it forth and made in it firm mountains and caused to grow in it of every suitable thing.
   

8. 17:35 وَأَوْفُوا۟ ٱلْكَيْلَ إِذَا كِلْتُمْ وَزِنُوا۟ بِٱلْقِسْطَاسِ ٱلْمُسْتَقِيمِ ذَٰلِكَ خَيْرٌ وَأَحْسَنُ تَأْوِيلًا

   And give full measure when you measure out, and weigh with a true balance; this is fair and better in the end.
   

9. 18:105 أُو۟لَٰٓئِكَ ٱلَّذِينَ كَفَرُوا۟ بِـَٔايَٰتِ رَبِّهِمْ وَلِقَآئِهِۦ فَحَبِطَتْ أَعْمَٰلُهُمْ فَلَا نُقِيمُ لَهُمْ يَوْمَ ٱلْقِيَٰمَةِ وَزْنًا

   These are they who disbelieve in the communications of their Lord and His meeting, so their deeds become null, and therefore We will not set up a balance for them on the day of resurrection.
   

10. 21:47 وَنَضَعُ ٱلْمَوَٰزِينَ ٱلْقِسْطَ لِيَوْمِ ٱلْقِيَٰمَةِ فَلَا تُظْلَمُ نَفْسٌ شَيْـًٔا وَإِن كَانَ مِثْقَالَ حَبَّةٍ مِّنْ خَرْدَلٍ أَتَيْنَا بِهَا وَكَفَىٰ بِنَا حَٰسِبِينَ

    And We will set up a just balance on the day of resurrection, so no soul shall be dealt with unjustly in the least; and though there be the weight of a grain of mustard seed, (yet) will We bring it, and sufficient are We to take account.
    

11. 23:102 فَمَن ثَقُلَتْ مَوَٰزِينُهُۥ فَأُو۟لَٰٓئِكَ هُمُ ٱلْمُفْلِحُونَ

    Then as for him whose good deeds are preponderant, these are the successful.
    

12. 23:103 وَمَنْ خَفَّتْ مَوَٰزِينُهُۥ فَأُو۟لَٰٓئِكَ ٱلَّذِينَ خَسِرُوٓا۟ أَنفُسَهُمْ فِى جَهَنَّمَ خَٰلِدُونَ

    And as for him whose good deeds are light, these are they who shall have lost their souls, abiding in hell
    

13. 26:182 وَزِنُوا۟ بِٱلْقِسْطَاسِ ٱلْمُسْتَقِيمِ

    And weigh (things) with a right balance,
    

14. 42:17 ٱللَّهُ ٱلَّذِىٓ أَنزَلَ ٱلْكِتَٰبَ بِٱلْحَقِّ وَٱلْمِيزَانَ وَمَا يُدْرِيكَ لَعَلَّ ٱلسَّاعَةَ قَرِيبٌ

    Allah it is Who revealed the Book with truth, and the balance, and what shall make you know that haply the hour be nigh?
    

15. 55:7 وَٱلسَّمَآءَ رَفَعَهَا وَوَضَعَ ٱلْمِيزَانَ

    And the heaven, He raised it high, and He made the balance
    

16. 55:8 أَلَّا تَطْغَوْا۟ فِى ٱلْمِيزَانِ

    That you may not be inordinate in respect of the measure.
    

17. 55:9 وَأَقِيمُوا۟ ٱلْوَزْنَ بِٱلْقِسْطِ وَلَا تُخْسِرُوا۟ ٱلْمِيزَانَ

    And keep up the balance with equity and do not make the measure deficient.
    

18. 57:25 لَقَدْ أَرْسَلْنَا رُسُلَنَا بِٱلْبَيِّنَٰتِ وَأَنزَلْنَا مَعَهُمُ ٱلْكِتَٰبَ وَٱلْمِيزَانَ لِيَقُومَ ٱلنَّاسُ بِٱلْقِسْطِ وَأَنزَلْنَا ٱلْحَدِيدَ فِيهِ بَأْسٌ شَدِيدٌ وَمَنَٰفِعُ لِلنَّاسِ وَلِيَعْلَمَ ٱللَّهُ مَن يَنصُرُهُۥ وَرُسُلَهُۥ بِٱلْغَيْبِ إِنَّ ٱللَّهَ قَوِىٌّ عَزِيزٌ

    Certainly We sent Our messengers with clear arguments, and sent down with them the Book and the balance that men may conduct themselves with equity; and We have made the iron, wherein is great violence and advantages to men, and that Allah may know who helps Him and His messengers in the secret; surely Allah is Strong, Mighty.
    

19. 83:3 وَإِذَا كَالُوهُمْ أَو وَّزَنُوهُمْ يُخْسِرُونَ

    But when they measure out to others or weigh out for them, they are deficient.
    

20. 101:6 فَأَمَّا مَن ثَقُلَتْ مَوَٰزِينُهُۥ

    Then as for him whose measure of good deeds is heavy,
    

21. 101:8 وَأَمَّا مَنْ خَفَّتْ مَوَٰزِينُهُۥ

    And as for him whose measure of good deeds is light,
