1. 2:251 فَهَزَمُوهُم بِإِذْنِ ٱللَّهِ وَقَتَلَ دَاوُۥدُ جَالُوتَ وَءَاتَىٰهُ ٱللَّهُ ٱلْمُلْكَ وَٱلْحِكْمَةَ وَعَلَّمَهُۥ مِمَّا يَشَآءُ وَلَوْلَا دَفْعُ ٱللَّهِ ٱلنَّاسَ بَعْضَهُم بِبَعْضٍ لَّفَسَدَتِ ٱلْأَرْضُ وَلَٰكِنَّ ٱللَّهَ ذُو فَضْلٍ عَلَى ٱلْعَٰلَمِينَ

   So they put them to flight by Allah's permission. And Dawood slew Jalut, and Allah gave him kingdom and wisdom, and taught him of what He pleased. And were it not for Allah's repelling some men with others, the earth would certainly be in a state of disorder; but Allah is Gracious to the creatures.
   

2. 3:167 وَلِيَعْلَمَ ٱلَّذِينَ نَافَقُوا۟ وَقِيلَ لَهُمْ تَعَالَوْا۟ قَٰتِلُوا۟ فِى سَبِيلِ ٱللَّهِ أَوِ ٱدْفَعُوا۟ قَالُوا۟ لَوْ نَعْلَمُ قِتَالًا لَّٱتَّبَعْنَٰكُمْ هُمْ لِلْكُفْرِ يَوْمَئِذٍ أَقْرَبُ مِنْهُمْ لِلْإِيمَٰنِ يَقُولُونَ بِأَفْوَٰهِهِم مَّا لَيْسَ فِى قُلُوبِهِمْ وَٱللَّهُ أَعْلَمُ بِمَا يَكْتُمُونَ

   And that He might know the hypocrites; and it was said to them: Come, fight in Allah's way, or defend yourselves. They said: If we knew fighting, we would certainly have followed you. They were on that day much nearer to unbelief than to belief. They say with their mouths what is not in their hearts, and Allah best knows what they conceal.
   

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. 22:38 إِنَّ ٱللَّهَ يُدَٰفِعُ عَنِ ٱلَّذِينَ ءَامَنُوٓا۟ إِنَّ ٱللَّهَ لَا يُحِبُّ كُلَّ خَوَّانٍ كَفُورٍ

   Surely Allah will defend those who believe; surely Allah does not love any one who is unfaithful, ungrateful.
   

5. 22:40 ٱلَّذِينَ أُخْرِجُوا۟ مِن دِيَٰرِهِم بِغَيْرِ حَقٍّ إِلَّآ أَن يَقُولُوا۟ رَبُّنَا ٱللَّهُ وَلَوْلَا دَفْعُ ٱللَّهِ ٱلنَّاسَ بَعْضَهُم بِبَعْضٍ لَّهُدِّمَتْ صَوَٰمِعُ وَبِيَعٌ وَصَلَوَٰتٌ وَمَسَٰجِدُ يُذْكَرُ فِيهَا ٱسْمُ ٱللَّهِ كَثِيرًا وَلَيَنصُرَنَّ ٱللَّهُ مَن يَنصُرُهُۥٓ إِنَّ ٱللَّهَ لَقَوِىٌّ عَزِيزٌ

   Those who have been expelled from their homes without a just cause except that they say: Our Lord is Allah. And had there not been Allah's repelling some people by others, certainly there would have been pulled down cloisters and churches and synagogues and mosques in which Allah's name is much remembered; and surely Allah will help him who helps His cause; most surely Allah is Strong, Mighty.
   

6. 23:96 ٱدْفَعْ بِٱلَّتِى هِىَ أَحْسَنُ ٱلسَّيِّئَةَ نَحْنُ أَعْلَمُ بِمَا يَصِفُونَ

   Repel evil by what is best; We know best what they describe.
   

7. 41:34 وَلَا تَسْتَوِى ٱلْحَسَنَةُ وَلَا ٱلسَّيِّئَةُ ٱدْفَعْ بِٱلَّتِى هِىَ أَحْسَنُ فَإِذَا ٱلَّذِى بَيْنَكَ وَبَيْنَهُۥ عَدَٰوَةٌ كَأَنَّهُۥ وَلِىٌّ حَمِيمٌ

   And not alike are the good and the evil. Repel (evil) with what is best, when lo! he between whom and you was enmity would be as if he were a warm friend.
   

8. 52:8 مَّا لَهُۥ مِن دَافِعٍ

   There shall be none to avert it;
   

9. 70:2 لِّلْكَٰفِرِينَ لَيْسَ لَهُۥ دَافِعٌ

   The unbelievers-- there is none to avert it--
