1. 2:204 وَمِنَ ٱلنَّاسِ مَن يُعْجِبُكَ قَوْلُهُۥ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا وَيُشْهِدُ ٱللَّهَ عَلَىٰ مَا فِى قَلْبِهِۦ وَهُوَ أَلَدُّ ٱلْخِصَامِ

   And among men is he whose speech about the life of this world causes you to wonder, and he calls on Allah to witness as to what is in his heart, yet he is the most violent of adversaries.
   

2. 3:44 ذَٰلِكَ مِنْ أَنۢبَآءِ ٱلْغَيْبِ نُوحِيهِ إِلَيْكَ وَمَا كُنتَ لَدَيْهِمْ إِذْ يُلْقُونَ أَقْلَٰمَهُمْ أَيُّهُمْ يَكْفُلُ مَرْيَمَ وَمَا كُنتَ لَدَيْهِمْ إِذْ يَخْتَصِمُونَ

   This is of the announcements relating to the unseen which We reveal to you; and you were not with them when they cast their pens (to decide) which of them should have Marium in his charge, and you were not with them when they contended one with another.
   

3. 4:105 إِنَّآ أَنزَلْنَآ إِلَيْكَ ٱلْكِتَٰبَ بِٱلْحَقِّ لِتَحْكُمَ بَيْنَ ٱلنَّاسِ بِمَآ أَرَىٰكَ ٱللَّهُ وَلَا تَكُن لِّلْخَآئِنِينَ خَصِيمًا

   Surely We have revealed the Book to you with the truth that you may judge between people by means of that which Allah has taught you; and be not an advocate on behalf of the treacherous.
   

4. 16:4 خَلَقَ ٱلْإِنسَٰنَ مِن نُّطْفَةٍ فَإِذَا هُوَ خَصِيمٌ مُّبِينٌ

   He created man from a small seed and lo! he is an open contender.
   

5. 22:19 هَٰذَانِ خَصْمَانِ ٱخْتَصَمُوا۟ فِى رَبِّهِمْ فَٱلَّذِينَ كَفَرُوا۟ قُطِّعَتْ لَهُمْ ثِيَابٌ مِّن نَّارٍ يُصَبُّ مِن فَوْقِ رُءُوسِهِمُ ٱلْحَمِيمُ

   These are two adversaries who dispute about their Lord; then (as to) those who disbelieve, for them are cut out garments of fire, boiling water shall be poured over their heads.
   

6. 26:96 قَالُوا۟ وَهُمْ فِيهَا يَخْتَصِمُونَ

   They shall say while they contend therein:
   

7. 27:45 وَلَقَدْ أَرْسَلْنَآ إِلَىٰ ثَمُودَ أَخَاهُمْ صَٰلِحًا أَنِ ٱعْبُدُوا۟ ٱللَّهَ فَإِذَا هُمْ فَرِيقَانِ يَخْتَصِمُونَ

   And certainly We sent to Samood their brother Salih, saying: Serve Allah; and lo! they became two sects quarrelling with each other.
   

8. 36:49 مَا يَنظُرُونَ إِلَّا صَيْحَةً وَٰحِدَةً تَأْخُذُهُمْ وَهُمْ يَخِصِّمُونَ

   They wait not for aught but a single cry which will overtake them while they yet contend with one another.
   

9. 36:77 أَوَلَمْ يَرَ ٱلْإِنسَٰنُ أَنَّا خَلَقْنَٰهُ مِن نُّطْفَةٍ فَإِذَا هُوَ خَصِيمٌ مُّبِينٌ

   Does not man see that We have created him from the small seed? Then lo! he is an open disputant.
   

10. 38:21 وَهَلْ أَتَىٰكَ نَبَؤُا۟ ٱلْخَصْمِ إِذْ تَسَوَّرُوا۟ ٱلْمِحْرَابَ

    And has there come to you the story of the litigants, when they made an entry into the private chamber by ascending over the walls?
    

11. 38:22 إِذْ دَخَلُوا۟ عَلَىٰ دَاوُۥدَ فَفَزِعَ مِنْهُمْ قَالُوا۟ لَا تَخَفْ خَصْمَانِ بَغَىٰ بَعْضُنَا عَلَىٰ بَعْضٍ فَٱحْكُم بَيْنَنَا بِٱلْحَقِّ وَلَا تُشْطِطْ وَٱهْدِنَآ إِلَىٰ سَوَآءِ ٱلصِّرَٰطِ

    When they entered in upon Dawood and he was frightened at them, they said: Fear not; two litigants, of whom one has acted wrongfully towards the other, therefore decide between us with justice, and do not act unjustly, and guide us to the right way.
    

12. 38:64 إِنَّ ذَٰلِكَ لَحَقٌّ تَخَاصُمُ أَهْلِ ٱلنَّارِ

    That most surely is the truth: the contending one with another of the inmates of the fire.
    

13. 38:69 مَا كَانَ لِىَ مِنْ عِلْمٍۭ بِٱلْمَلَإِ ٱلْأَعْلَىٰٓ إِذْ يَخْتَصِمُونَ

    I had no knowledge of the exalted chiefs when they contended:
    

14. 39:31 ثُمَّ إِنَّكُمْ يَوْمَ ٱلْقِيَٰمَةِ عِندَ رَبِّكُمْ تَخْتَصِمُونَ

    Then surely on the day of resurrection you will contend one with another before. your Lord.
    

15. 43:18 أَوَمَن يُنَشَّؤُا۟ فِى ٱلْحِلْيَةِ وَهُوَ فِى ٱلْخِصَامِ غَيْرُ مُبِينٍ

    What! that which is made in ornaments and which in contention is unable to make plain speech!
    

16. 43:58 وَقَالُوٓا۟ ءَأَٰلِهَتُنَا خَيْرٌ أَمْ هُوَ مَا ضَرَبُوهُ لَكَ إِلَّا جَدَلًۢا بَلْ هُمْ قَوْمٌ خَصِمُونَ

    And they say: Are our gods better, or is he? They do not set it forth to you save by way of disputation; nay, they are a contentious people.
    

17. 50:28 قَالَ لَا تَخْتَصِمُوا۟ لَدَىَّ وَقَدْ قَدَّمْتُ إِلَيْكُم بِٱلْوَعِيدِ

    He will say: Do not quarrel in My presence, and indeed I gave you the threatening beforehand:
