1. 6:31 قَدْ خَسِرَ ٱلَّذِينَ كَذَّبُوا۟ بِلِقَآءِ ٱللَّهِ حَتَّىٰٓ إِذَا جَآءَتْهُمُ ٱلسَّاعَةُ بَغْتَةً قَالُوا۟ يَٰحَسْرَتَنَا عَلَىٰ مَا فَرَّطْنَا فِيهَا وَهُمْ يَحْمِلُونَ أَوْزَارَهُمْ عَلَىٰ ظُهُورِهِمْ أَلَا سَآءَ مَا يَزِرُونَ

   They are losers indeed who reject the meeting of Allah; until when the hour comes upon them all of a sudden they shall say: O our grief for our neglecting it! and they shall bear their burdens on their backs; now surely evil is that which they bear.
   

2. 6:38 وَمَا مِن دَآبَّةٍ فِى ٱلْأَرْضِ وَلَا طَٰٓئِرٍ يَطِيرُ بِجَنَاحَيْهِ إِلَّآ أُمَمٌ أَمْثَالُكُم مَّا فَرَّطْنَا فِى ٱلْكِتَٰبِ مِن شَىْءٍ ثُمَّ إِلَىٰ رَبِّهِمْ يُحْشَرُونَ

   And there is no animal that walks upon the earth nor a bird that flies with its two wings but (they are) genera like yourselves; We have not neglected anything in the Book, then to their Lord shall they be gathered.
   

3. 6:61 وَهُوَ ٱلْقَاهِرُ فَوْقَ عِبَادِهِۦ وَيُرْسِلُ عَلَيْكُمْ حَفَظَةً حَتَّىٰٓ إِذَا جَآءَ أَحَدَكُمُ ٱلْمَوْتُ تَوَفَّتْهُ رُسُلُنَا وَهُمْ لَا يُفَرِّطُونَ

   And He is the Supreme, above His servants, and He sends keepers over you; until when death comes to one of you, Our messengers cause him to die, and they are not remiss.
   

4. 12:80 فَلَمَّا ٱسْتَيْـَٔسُوا۟ مِنْهُ خَلَصُوا۟ نَجِيًّا قَالَ كَبِيرُهُمْ أَلَمْ تَعْلَمُوٓا۟ أَنَّ أَبَاكُمْ قَدْ أَخَذَ عَلَيْكُم مَّوْثِقًا مِّنَ ٱللَّهِ وَمِن قَبْلُ مَا فَرَّطتُمْ فِى يُوسُفَ فَلَنْ أَبْرَحَ ٱلْأَرْضَ حَتَّىٰ يَأْذَنَ لِىٓ أَبِىٓ أَوْ يَحْكُمَ ٱللَّهُ لِى وَهُوَ خَيْرُ ٱلْحَٰكِمِينَ

   Then when they despaired of him, they retired, conferring privately together. The eldest of them said: Do you not know that your father took from you a covenant in Allah's name, and how you fell short of your duty with respect to Yusuf before? Therefore I will by no means depart from this land until my father permits me or Allah decides for me, and He is the best of the judges:
   

5. 16:62 وَيَجْعَلُونَ لِلَّهِ مَا يَكْرَهُونَ وَتَصِفُ أَلْسِنَتُهُمُ ٱلْكَذِبَ أَنَّ لَهُمُ ٱلْحُسْنَىٰ لَا جَرَمَ أَنَّ لَهُمُ ٱلنَّارَ وَأَنَّهُم مُّفْرَطُونَ

   And they ascribe to Allah what they (themselves) hate and their tongues relate the lie that they shall have the good; there is no avoiding it that for them is the fire and that they shall be sent before.
   

6. 18:28 وَٱصْبِرْ نَفْسَكَ مَعَ ٱلَّذِينَ يَدْعُونَ رَبَّهُم بِٱلْغَدَوٰةِ وَٱلْعَشِىِّ يُرِيدُونَ وَجْهَهُۥ وَلَا تَعْدُ عَيْنَاكَ عَنْهُمْ تُرِيدُ زِينَةَ ٱلْحَيَوٰةِ ٱلدُّنْيَا وَلَا تُطِعْ مَنْ أَغْفَلْنَا قَلْبَهُۥ عَن ذِكْرِنَا وَٱتَّبَعَ هَوَىٰهُ وَكَانَ أَمْرُهُۥ فُرُطًا

   And withhold yourself with those who call on their Lord morning and evening desiring His goodwill, and let not your eyes pass from them, desiring the beauties of this world's life; and do not follow him whose heart We have made unmindful to Our remembrance, and he follows his low desires and his case is one in which due bounds are exceeded.
   

7. 20:45 قَالَا رَبَّنَآ إِنَّنَا نَخَافُ أَن يَفْرُطَ عَلَيْنَآ أَوْ أَن يَطْغَىٰ

   Both said: O our Lord! Surely we fear that he may hasten to do evil to us or that he may become inordinate.
   

8. 39:56 أَن تَقُولَ نَفْسٌ يَٰحَسْرَتَىٰ عَلَىٰ مَا فَرَّطتُ فِى جَنۢبِ ٱللَّهِ وَإِن كُنتُ لَمِنَ ٱلسَّٰخِرِينَ

   Lest a soul should say: O woe to me! for what I fell short of my duty to Allah, and most surely I was of those who laughed to scorn;
