17:92
أَوْ تُسْقِطَ ٱل سَّمَآءَ كَ مَا زَعَمْ تَ عَلَيْ نَا كِسَفًا أَوْ تَأْتِىَ بِ ٱللَّهِ وَ ٱلْ مَلَٰٓئِكَةِ قَبِيلًا
Or you make the heaven fall upon us in fragments as you have claimed or you bring Allah and the angels before [us]
26:187
فَ أَسْقِطْ عَلَيْ نَا كِسَفًا مِّنَ ٱل سَّمَآءِ إِن كُن تَ مِنَ ٱل صَّٰدِقِينَ
So cause to fall upon us fragments of the sky, if you should be of the truthful."
34:9
أَ فَ لَمْ يَرَ وْا۟ إِلَىٰ مَا بَيْنَ أَيْدِي هِمْ وَ مَا خَلْفَ هُم مِّنَ ٱل سَّمَآءِ وَ ٱلْ أَرْضِ إِن نَّشَأْ نَخْسِفْ بِ هِمُ ٱلْ أَرْضَ أَوْ نُسْقِطْ عَلَيْ هِمْ كِسَفًا مِّنَ ٱل سَّمَآءِ إِنَّ فِى ذَٰلِكَ لَ ءَايَةً لِّ كُلِّ عَبْدٍ مُّنِيبٍ
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 Allah].
