1. 2:143 وَكَذَٰلِكَ جَعَلْنَٰكُمْ أُمَّةً وَسَطًا لِّتَكُونُوا۟ شُهَدَآءَ عَلَى ٱلنَّاسِ وَيَكُونَ ٱلرَّسُولُ عَلَيْكُمْ شَهِيدًا وَمَا جَعَلْنَا ٱلْقِبْلَةَ ٱلَّتِى كُنتَ عَلَيْهَآ إِلَّا لِنَعْلَمَ مَن يَتَّبِعُ ٱلرَّسُولَ مِمَّن يَنقَلِبُ عَلَىٰ عَقِبَيْهِ وَإِن كَانَتْ لَكَبِيرَةً إِلَّا عَلَى ٱلَّذِينَ هَدَى ٱللَّهُ وَمَا كَانَ ٱللَّهُ لِيُضِيعَ إِيمَٰنَكُمْ إِنَّ ٱللَّهَ بِٱلنَّاسِ لَرَءُوفٌ رَّحِيمٌ

   And thus We have made you a medium (just) nation that you may be the bearers of witness to the people and (that) the Messenger may be a bearer of witness to you; and We did not make that which you would have to be the qiblah but that We might distinguish him who follows the Messenger from him who turns back upon his heels, and this was surely hard except for those whom Allah has guided aright; and Allah was not going to make your faith to be fruitless; most surely Allah is Affectionate, Merciful to the people.
   

2. 3:171 يَسْتَبْشِرُونَ بِنِعْمَةٍ مِّنَ ٱللَّهِ وَفَضْلٍ وَأَنَّ ٱللَّهَ لَا يُضِيعُ أَجْرَ ٱلْمُؤْمِنِينَ

   They rejoice on account of favor from Allah and (His) grace, and that Allah will not waste the reward of the believers.
   

3. 3:195 فَٱسْتَجَابَ لَهُمْ رَبُّهُمْ أَنِّى لَآ أُضِيعُ عَمَلَ عَٰمِلٍ مِّنكُم مِّن ذَكَرٍ أَوْ أُنثَىٰ بَعْضُكُم مِّنۢ بَعْضٍ فَٱلَّذِينَ هَاجَرُوا۟ وَأُخْرِجُوا۟ مِن دِيَٰرِهِمْ وَأُوذُوا۟ فِى سَبِيلِى وَقَٰتَلُوا۟ وَقُتِلُوا۟ لَأُكَفِّرَنَّ عَنْهُمْ سَيِّـَٔاتِهِمْ وَلَأُدْخِلَنَّهُمْ جَنَّٰتٍ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَٰرُ ثَوَابًا مِّنْ عِندِ ٱللَّهِ وَٱللَّهُ عِندَهُۥ حُسْنُ ٱلثَّوَابِ

   So their Lord accepted their prayer: That I will not waste the work of a worker among you, whether male or female, the one of you being from the other; they, therefore, who fled and were turned out of their homes and persecuted in My way and who fought and were slain, I will most certainly cover their evil deeds, and I will most certainly make them enter gardens beneath which rivers flow; a reward from Allah, and with Allah is yet better reward.
   

4. 7:170 وَٱلَّذِينَ يُمَسِّكُونَ بِٱلْكِتَٰبِ وَأَقَامُوا۟ ٱلصَّلَوٰةَ إِنَّا لَا نُضِيعُ أَجْرَ ٱلْمُصْلِحِينَ

   And (as for) those who hold fast by the Book and keep up prayer, surely We do not waste the reward of the right doers.
   

5. 9:120 مَا كَانَ لِأَهْلِ ٱلْمَدِينَةِ وَمَنْ حَوْلَهُم مِّنَ ٱلْأَعْرَابِ أَن يَتَخَلَّفُوا۟ عَن رَّسُولِ ٱللَّهِ وَلَا يَرْغَبُوا۟ بِأَنفُسِهِمْ عَن نَّفْسِهِۦ ذَٰلِكَ بِأَنَّهُمْ لَا يُصِيبُهُمْ ظَمَأٌ وَلَا نَصَبٌ وَلَا مَخْمَصَةٌ فِى سَبِيلِ ٱللَّهِ وَلَا يَطَـُٔونَ مَوْطِئًا يَغِيظُ ٱلْكُفَّارَ وَلَا يَنَالُونَ مِنْ عَدُوٍّ نَّيْلًا إِلَّا كُتِبَ لَهُم بِهِۦ عَمَلٌ صَٰلِحٌ إِنَّ ٱللَّهَ لَا يُضِيعُ أَجْرَ ٱلْمُحْسِنِينَ

   It did not beseem the people of Medina and those round about them of the dwellers of the desert to remain behind the Messenger of Allah, nor should they desire (anything) for themselves in preference to him; this is because there afflicts them not thirst or fatigue or hunger in Allah's way, nor do they tread a path which enrages the unbelievers, nor do they attain from the enemy what they attain, but a good work is written down to them on account of it; surely Allah does not waste the reward of the doers of good;
   

6. 11:115 وَٱصْبِرْ فَإِنَّ ٱللَّهَ لَا يُضِيعُ أَجْرَ ٱلْمُحْسِنِينَ

   And be patient, for surely Allah does not waste the reward of the good-doers.
   

7. 12:56 وَكَذَٰلِكَ مَكَّنَّا لِيُوسُفَ فِى ٱلْأَرْضِ يَتَبَوَّأُ مِنْهَا حَيْثُ يَشَآءُ نُصِيبُ بِرَحْمَتِنَا مَن نَّشَآءُ وَلَا نُضِيعُ أَجْرَ ٱلْمُحْسِنِينَ

   And thus did We give to Yusuf power in the land-- he had mastery in it wherever he liked; We send down Our mercy on whom We please, and We do not waste the reward of those who do good.
   

8. 12:90 قَالُوٓا۟ أَءِنَّكَ لَأَنتَ يُوسُفُ قَالَ أَنَا۠ يُوسُفُ وَهَٰذَآ أَخِى قَدْ مَنَّ ٱللَّهُ عَلَيْنَآ إِنَّهُۥ مَن يَتَّقِ وَيَصْبِرْ فَإِنَّ ٱللَّهَ لَا يُضِيعُ أَجْرَ ٱلْمُحْسِنِينَ

   They said: Are you indeed Yusuf? He said: I am Yusuf and this is my brother; Allah has indeed been gracious to us; surely he who guards (against evil) and is patient (is rewarded) for surely Allah does not waste the reward of those who do good.
   

9. 18:30 إِنَّ ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ إِنَّا لَا نُضِيعُ أَجْرَ مَنْ أَحْسَنَ عَمَلًا

   Surely (as for) those who believe and do good, We do not waste the reward of him who does a good work.
   

10. 19:59 فَخَلَفَ مِنۢ بَعْدِهِمْ خَلْفٌ أَضَاعُوا۟ ٱلصَّلَوٰةَ وَٱتَّبَعُوا۟ ٱلشَّهَوَٰتِ فَسَوْفَ يَلْقَوْنَ غَيًّا

    But there came after them an evil generation, who neglected prayers and followed and sensual desires, so they win meet perdition,
