1. 16:45 أَفَأَمِنَ ٱلَّذِينَ مَكَرُوا۟ ٱلسَّيِّـَٔاتِ أَن يَخْسِفَ ٱللَّهُ بِهِمُ ٱلْأَرْضَ أَوْ يَأْتِيَهُمُ ٱلْعَذَابُ مِنْ حَيْثُ لَا يَشْعُرُونَ

   Do they then who plan evil (deeds) feel secure (of this) that Allah will not cause the earth to swallow them or that punishment may not overtake them from whence they do not perceive?
   

2. 17:68 أَفَأَمِنتُمْ أَن يَخْسِفَ بِكُمْ جَانِبَ ٱلْبَرِّ أَوْ يُرْسِلَ عَلَيْكُمْ حَاصِبًا ثُمَّ لَا تَجِدُوا۟ لَكُمْ وَكِيلًا

   What! Do you then feel secure that He will not cause a tract of land to engulf you or send on you a tornado? Then you shall not find a protector for yourselves.
   

3. 28:81 فَخَسَفْنَا بِهِۦ وَبِدَارِهِ ٱلْأَرْضَ فَمَا كَانَ لَهُۥ مِن فِئَةٍ يَنصُرُونَهُۥ مِن دُونِ ٱللَّهِ وَمَا كَانَ مِنَ ٱلْمُنتَصِرِينَ

   Thus We made the earth to swallow up him and his abode; so he had no body of helpers to assist him against Allah nor was he of those who can defend themselves.
   

4. 28:82 وَأَصْبَحَ ٱلَّذِينَ تَمَنَّوْا۟ مَكَانَهُۥ بِٱلْأَمْسِ يَقُولُونَ وَيْكَأَنَّ ٱللَّهَ يَبْسُطُ ٱلرِّزْقَ لِمَن يَشَآءُ مِنْ عِبَادِهِۦ وَيَقْدِرُ لَوْلَآ أَن مَّنَّ ٱللَّهُ عَلَيْنَا لَخَسَفَ بِنَا وَيْكَأَنَّهُۥ لَا يُفْلِحُ ٱلْكَٰفِرُونَ

   And those who yearned for his place only the day before began to say: Ah! (know) that Allah amplifies and straitens the means of subsistence for whom He pleases of His servants; had not Allah been gracious to us, He would most surely have abased us; ah! (know) that the ungrateful are never successful.
   

5. 29:40 فَكُلًّا أَخَذْنَا بِذَنۢبِهِۦ فَمِنْهُم مَّنْ أَرْسَلْنَا عَلَيْهِ حَاصِبًا وَمِنْهُم مَّنْ أَخَذَتْهُ ٱلصَّيْحَةُ وَمِنْهُم مَّنْ خَسَفْنَا بِهِ ٱلْأَرْضَ وَمِنْهُم مَّنْ أَغْرَقْنَا وَمَا كَانَ ٱللَّهُ لِيَظْلِمَهُمْ وَلَٰكِن كَانُوٓا۟ أَنفُسَهُمْ يَظْلِمُونَ

   So each We punished for his sin; of them was he on whom We sent down a violent storm, and of them was he whom the rumbling overtook, and of them was he whom We made to be swallowed up by the earth, and of them was he whom We drowned; and it did not beseem Allah that He should be unjust to them, but they were unjust to their own souls.
   

6. 34:9 أَفَلَمْ يَرَوْا۟ إِلَىٰ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُم مِّنَ ٱلسَّمَآءِ وَٱلْأَرْضِ إِن نَّشَأْ نَخْسِفْ بِهِمُ ٱلْأَرْضَ أَوْ نُسْقِطْ عَلَيْهِمْ كِسَفًا مِّنَ ٱلسَّمَآءِ إِنَّ فِى ذَٰلِكَ لَءَايَةً لِّكُلِّ عَبْدٍ مُّنِيبٍ

   Do they not then consider what is before them and what is behind them of the heaven and the earth? If We please We will make them disappear in the land or bring down upon them a portion from the heaven; most surely there is a sign in this for every servant turning (to Allah).
   

7. 67:16 ءَأَمِنتُم مَّن فِى ٱلسَّمَآءِ أَن يَخْسِفَ بِكُمُ ٱلْأَرْضَ فَإِذَا هِىَ تَمُورُ

   Are you secure of those in the heaven that He should not make the earth to swallow you up? Then lo! it shall be in a state of commotion.
   

8. 75:8 وَخَسَفَ ٱلْقَمَرُ

   And the moon becomes dark,
