The root خ س ف (kh-s-f) in the Quran

أَفَأَمِنَ ٱلَّذِينَ مَكَرُوا۟ ٱلسَّيِّـَٔاتِ أَن يَخْسِفَ ٱللَّهُ بِهِمُ ٱلْأَرْضَ أَوْ يَأْتِيَهُمُ ٱلْعَذَابُ مِنْ حَيْثُ لَا يَشْعُرُونَ ۝٤٥

Then, do those who have planned evil deeds feel secure that Allāh will not cause the earth to swallow them or that the punishment will not come upon them from where they do not perceive?

أَفَأَمِنتُمْ أَن يَخْسِفَ بِكُمْ جَانِبَ ٱلْبَرِّ أَوْ يُرْسِلَ عَلَيْكُمْ حَاصِبًا ثُمَّ لَا تَجِدُوا۟ لَكُمْ وَكِيلًا ۝٦٨

Then do you feel secure that [instead] He will not cause a part of the land to swallow you or send against you a storm of stones? Then you would not find for yourselves an advocate.

فَخَسَفْنَا بِهِۦ وَبِدَارِهِ ٱلْأَرْضَ فَمَا كَانَ لَهُۥ مِن فِئَةٍ يَنصُرُونَهُۥ مِن دُونِ ٱللَّهِ وَمَا كَانَ مِنَ ٱلْمُنتَصِرِينَ ۝٨١

And We caused the earth to swallow him and his home. And there was for him no company to aid him other than Allāh, nor was he of those who [could] defend themselves.

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 ۝٨٢

And those who had wished for his position the previous day began to say, "Oh, how Allāh extends provision to whom He wills of His servants and restricts it! If not that Allāh had conferred favor on us, He would have caused it to swallow us. Oh, how the disbelievers do not succeed!"

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 ۝٤٠

So each We seized for his sin; and among them were those upon whom We sent a storm of stones, and among them were those who were seized by the blast [from the sky], and among them were those whom We caused the earth to swallow, and among them were those whom We drowned. And Allāh would not have wronged them, but it was they who were wronging themselves.

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 لَـَٔايَةً لِّكُلِّ عَبْدٍ مُّنِيبٍ ۝٩

Then, do they not look at what is before them and what is behind them of the heaven and earth? If We should will, We could cause the earth to swallow them or [could] let fall upon them fragments from the sky. Indeed in that is a sign for every servant turning back [to Allāh].

ءَأَمِنتُم مَّن فِى ٱلسَّمَآءِ أَن يَخْسِفَ بِكُمُ ٱلْأَرْضَ فَإِذَا هِىَ تَمُورُ ۝١٦

Do you feel secure that He who is above would not cause the earth to swallow you and suddenly it would sway?

وَخَسَفَ ٱلْقَمَرُ ۝٨

And the moon darkens
