1. 2:137 فَإِنْ ءَامَنُوا۟ بِمِثْلِ مَآ ءَامَنتُم بِهِۦ فَقَدِ ٱهْتَدَوا۟ وَّإِن تَوَلَّوْا۟ فَإِنَّمَا هُمْ فِى شِقَاقٍ فَسَيَكْفِيكَهُمُ ٱللَّهُ وَهُوَ ٱلسَّمِيعُ ٱلْعَلِيمُ

   If then they believe as you believe in Him, they are indeed on the right course, and if they turn back, then they are only in great opposition, so Allah will suffice you against them, and He is the Hearing, the Knowing.
   

2. 3:124 إِذْ تَقُولُ لِلْمُؤْمِنِينَ أَلَن يَكْفِيَكُمْ أَن يُمِدَّكُمْ رَبُّكُم بِثَلَٰثَةِ ءَالَٰفٍ مِّنَ ٱلْمَلَٰٓئِكَةِ مُنزَلِينَ

3. 4:6 وَٱبْتَلُوا۟ ٱلْيَتَٰمَىٰ حَتَّىٰٓ إِذَا بَلَغُوا۟ ٱلنِّكَاحَ فَإِنْ ءَانَسْتُم مِّنْهُمْ رُشْدًا فَٱدْفَعُوٓا۟ إِلَيْهِمْ أَمْوَٰلَهُمْ وَلَا تَأْكُلُوهَآ إِسْرَافًا وَبِدَارًا أَن يَكْبَرُوا۟ وَمَن كَانَ غَنِيًّا فَلْيَسْتَعْفِفْ وَمَن كَانَ فَقِيرًا فَلْيَأْكُلْ بِٱلْمَعْرُوفِ فَإِذَا دَفَعْتُمْ إِلَيْهِمْ أَمْوَٰلَهُمْ فَأَشْهِدُوا۟ عَلَيْهِمْ وَكَفَىٰ بِٱللَّهِ حَسِيبًا

   And test the orphans until they attain puberty; then if you find in them maturity of intellect, make over to them their property, and do not consume it extravagantly and hastily, lest they attain to full age; and whoever is rich, let him abstain altogether, and whoever is poor, let him eat reasonably; then when you make over to them their property, call witnesses in their presence; and Allah is enough as a Reckoner.
   

4. 4:45 وَٱللَّهُ أَعْلَمُ بِأَعْدَآئِكُمْ وَكَفَىٰ بِٱللَّهِ وَلِيًّا وَكَفَىٰ بِٱللَّهِ نَصِيرًا

   And Allah best knows your enemies; and Allah suffices as a Guardian, and Allah suffices as a Helper.
   

5. 4:50 ٱنظُرْ كَيْفَ يَفْتَرُونَ عَلَى ٱللَّهِ ٱلْكَذِبَ وَكَفَىٰ بِهِۦٓ إِثْمًا مُّبِينًا

   See how they forge the lie against Allah, and this is sufficient as a manifest sin.
   

6. 4:55 فَمِنْهُم مَّنْ ءَامَنَ بِهِۦ وَمِنْهُم مَّن صَدَّ عَنْهُ وَكَفَىٰ بِجَهَنَّمَ سَعِيرًا

   So of them is he who believes in him, and of them is he who turns away from him, and hell is sufficient to burn.
   

7. 4:70 ذَٰلِكَ ٱلْفَضْلُ مِنَ ٱللَّهِ وَكَفَىٰ بِٱللَّهِ عَلِيمًا

   This is grace from Allah, and sufficient is Allah as the Knower.
   

8. 4:79 مَّآ أَصَابَكَ مِنْ حَسَنَةٍ فَمِنَ ٱللَّهِ وَمَآ أَصَابَكَ مِن سَيِّئَةٍ فَمِن نَّفْسِكَ وَأَرْسَلْنَٰكَ لِلنَّاسِ رَسُولًا وَكَفَىٰ بِٱللَّهِ شَهِيدًا

   Whatever benefit comes to you (O man!), it is from Allah, and whatever misfortune befalls you, it is from yourself, and We have sent you (O Prophet!), to mankind as a messenger; and Allah is sufficient as a witness.
   

9. 4:81 وَيَقُولُونَ طَاعَةٌ فَإِذَا بَرَزُوا۟ مِنْ عِندِكَ بَيَّتَ طَآئِفَةٌ مِّنْهُمْ غَيْرَ ٱلَّذِى تَقُولُ وَٱللَّهُ يَكْتُبُ مَا يُبَيِّتُونَ فَأَعْرِضْ عَنْهُمْ وَتَوَكَّلْ عَلَى ٱللَّهِ وَكَفَىٰ بِٱللَّهِ وَكِيلًا

   And they say: Obedience. But when they go out from your presence, a party of them decide by night upon doing otherwise than what you say; and Allah writes down what they decide by night, therefore turn aside from them and trust in Allah, and Allah is sufficient as a protector.
   

10. 4:132 وَلِلَّهِ مَا فِى ٱلسَّمَٰوَٰتِ وَمَا فِى ٱلْأَرْضِ وَكَفَىٰ بِٱللَّهِ وَكِيلًا

    And whatever is in the heavens and whatever is in the earth is Allah's, and Allah is sufficient as a Protector.
    

11. 4:166 لَّٰكِنِ ٱللَّهُ يَشْهَدُ بِمَآ أَنزَلَ إِلَيْكَ أَنزَلَهُۥ بِعِلْمِهِۦ وَٱلْمَلَٰٓئِكَةُ يَشْهَدُونَ وَكَفَىٰ بِٱللَّهِ شَهِيدًا

    But Allah bears witness by what He has revealed to you that He has revealed it with His knowledge, and the angels bear witness (also); and Allah is sufficient as a witness.
    

12. 4:171 يَٰٓأَهْلَ ٱلْكِتَٰبِ لَا تَغْلُوا۟ فِى دِينِكُمْ وَلَا تَقُولُوا۟ عَلَى ٱللَّهِ إِلَّا ٱلْحَقَّ إِنَّمَا ٱلْمَسِيحُ عِيسَى ٱبْنُ مَرْيَمَ رَسُولُ ٱللَّهِ وَكَلِمَتُهُۥٓ أَلْقَىٰهَآ إِلَىٰ مَرْيَمَ وَرُوحٌ مِّنْهُ فَـَٔامِنُوا۟ بِٱللَّهِ وَرُسُلِهِۦ وَلَا تَقُولُوا۟ ثَلَٰثَةٌ ٱنتَهُوا۟ خَيْرًا لَّكُمْ إِنَّمَا ٱللَّهُ إِلَٰهٌ وَٰحِدٌ سُبْحَٰنَهُۥٓ أَن يَكُونَ لَهُۥ وَلَدٌ لَّهُۥ مَا فِى ٱلسَّمَٰوَٰتِ وَمَا فِى ٱلْأَرْضِ وَكَفَىٰ بِٱللَّهِ وَكِيلًا

    O followers of the Book! do not exceed the limits in your religion, and do not speak (lies) against Allah, but (speak) the truth; the Messiah, Isa son of Marium is only a messenger of Allah and His Word which He communicated to Marium and a spirit from Him; believe therefore in Allah and His messengers, and say not, Three. Desist, it is better for you; Allah is only one Allah; far be It from His glory that He should have a son, whatever is in the heavens and whatever is in the earth is His, and Allah is sufficient for a Protector.
    

13. 10:29 فَكَفَىٰ بِٱللَّهِ شَهِيدًۢا بَيْنَنَا وَبَيْنَكُمْ إِن كُنَّا عَنْ عِبَادَتِكُمْ لَغَٰفِلِينَ

    Therefore Allah is sufficient as a witness between us and you that we were quite unaware of your serving (us).
    

14. 13:43 وَيَقُولُ ٱلَّذِينَ كَفَرُوا۟ لَسْتَ مُرْسَلًا قُلْ كَفَىٰ بِٱللَّهِ شَهِيدًۢا بَيْنِى وَبَيْنَكُمْ وَمَنْ عِندَهُۥ عِلْمُ ٱلْكِتَٰبِ

    And those who disbelieve say: You are not a messenger. Say: Allah is sufficient as a witness between me and you and whoever has knowledge of the Book.
    

15. 15:95 إِنَّا كَفَيْنَٰكَ ٱلْمُسْتَهْزِءِينَ

    Surely We will suffice you against the scoffers
    

16. 17:14 ٱقْرَأْ كِتَٰبَكَ كَفَىٰ بِنَفْسِكَ ٱلْيَوْمَ عَلَيْكَ حَسِيبًا

    Read your book; your own self is sufficient as a reckoner against you this day.
    

17. 17:17 وَكَمْ أَهْلَكْنَا مِنَ ٱلْقُرُونِ مِنۢ بَعْدِ نُوحٍ وَكَفَىٰ بِرَبِّكَ بِذُنُوبِ عِبَادِهِۦ خَبِيرًۢا بَصِيرًا

    And how many of the generations did We destroy after Nuh! and your Lord is sufficient as Knowing and Seeing with regard to His servants' faults.
    

18. 17:65 إِنَّ عِبَادِى لَيْسَ لَكَ عَلَيْهِمْ سُلْطَٰنٌ وَكَفَىٰ بِرَبِّكَ وَكِيلًا

    Surely (as for) My servants, you have no authority over them; and your Lord is sufficient as a Protector.
    

19. 17:96 قُلْ كَفَىٰ بِٱللَّهِ شَهِيدًۢا بَيْنِى وَبَيْنَكُمْ إِنَّهُۥ كَانَ بِعِبَادِهِۦ خَبِيرًۢا بَصِيرًا

    Say: Allah suffices as a witness between me and you; surely He is Aware of His servants, Seeing.
    

20. 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.
    

21. 25:31 وَكَذَٰلِكَ جَعَلْنَا لِكُلِّ نَبِىٍّ عَدُوًّا مِّنَ ٱلْمُجْرِمِينَ وَكَفَىٰ بِرَبِّكَ هَادِيًا وَنَصِيرًا

    And thus have We made for every prophet an enemy from among the sinners and sufficient is your Lord as a Guide and a Helper.
    

22. 25:58 وَتَوَكَّلْ عَلَى ٱلْحَىِّ ٱلَّذِى لَا يَمُوتُ وَسَبِّحْ بِحَمْدِهِۦ وَكَفَىٰ بِهِۦ بِذُنُوبِ عِبَادِهِۦ خَبِيرًا

    And rely on the Ever-living Who dies not, and celebrate His praise; and Sufficient is He as being aware of the faults of His servants,
    

23. 29:51 أَوَلَمْ يَكْفِهِمْ أَنَّآ أَنزَلْنَا عَلَيْكَ ٱلْكِتَٰبَ يُتْلَىٰ عَلَيْهِمْ إِنَّ فِى ذَٰلِكَ لَرَحْمَةً وَذِكْرَىٰ لِقَوْمٍ يُؤْمِنُونَ

    Is it not enough for them that We have revealed to you the Book which is recited to them? Most surely there is mercy in this and a reminder for a people who believe.
    

24. 29:52 قُلْ كَفَىٰ بِٱللَّهِ بَيْنِى وَبَيْنَكُمْ شَهِيدًا يَعْلَمُ مَا فِى ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ وَٱلَّذِينَ ءَامَنُوا۟ بِٱلْبَٰطِلِ وَكَفَرُوا۟ بِٱللَّهِ أُو۟لَٰٓئِكَ هُمُ ٱلْخَٰسِرُونَ

    And Allah turned back the unbelievers in their rage; they did not obtain any advantage, and Allah sufficed the believers in fighting; and Allah is Strong, Mighty.
    

27. 33:39 ٱلَّذِينَ يُبَلِّغُونَ رِسَٰلَٰتِ ٱللَّهِ وَيَخْشَوْنَهُۥ وَلَا يَخْشَوْنَ أَحَدًا إِلَّا ٱللَّهَ وَكَفَىٰ بِٱللَّهِ حَسِيبًا

    Those who deliver the messages of Allah and fear Him, and do not fear any one but Allah; and Allah is sufficient to take account.
    

28. 33:48 وَلَا تُطِعِ ٱلْكَٰفِرِينَ وَٱلْمُنَٰفِقِينَ وَدَعْ أَذَىٰهُمْ وَتَوَكَّلْ عَلَى ٱللَّهِ وَكَفَىٰ بِٱللَّهِ وَكِيلًا

    Is not Allah sufficient for His servant? And they seek to frighten you with those besides Him; and whomsoever Allah makes err, there is no guide for him.
    

30. 41:53 سَنُرِيهِمْ ءَايَٰتِنَا فِى ٱلْءَافَاقِ وَفِىٓ أَنفُسِهِمْ حَتَّىٰ يَتَبَيَّنَ لَهُمْ أَنَّهُ ٱلْحَقُّ أَوَلَمْ يَكْفِ بِرَبِّكَ أَنَّهُۥ عَلَىٰ كُلِّ شَىْءٍ شَهِيدٌ

    We will soon show them Our signs in the Universe and in their own souls, until it will become quite clear to them that it is the truth. Is it not sufficient as regards your Lord that He is a witness over all things?
    

31. 46:8 أَمْ يَقُولُونَ ٱفْتَرَىٰهُ قُلْ إِنِ ٱفْتَرَيْتُهُۥ فَلَا تَمْلِكُونَ لِى مِنَ ٱللَّهِ شَيْـًٔا هُوَ أَعْلَمُ بِمَا تُفِيضُونَ فِيهِ كَفَىٰ بِهِۦ شَهِيدًۢا بَيْنِى وَبَيْنَكُمْ وَهُوَ ٱلْغَفُورُ ٱلرَّحِيمُ

    Nay! they say: He has forged it. Say: If I have forged it, you do not control anything for me from Allah; He knows best what you utter concerning it; He is enough as a witness between me and you, and He is the Forgiving, the Merciful.
    

32. 48:28 هُوَ ٱلَّذِىٓ أَرْسَلَ رَسُولَهُۥ بِٱلْهُدَىٰ وَدِينِ ٱلْحَقِّ لِيُظْهِرَهُۥ عَلَى ٱلدِّينِ كُلِّهِۦ وَكَفَىٰ بِٱللَّهِ شَهِيدًا

    He it is Who sent His Messenger with the guidance and the true religion that He may make it prevail over all the religions; and Allah is enough for a witness.
