ق-ر-ع

وَلَوْ أَنَّ قُرْءَانًا سُيِّرَتْ بِهِ ٱلْجِبَالُ أَوْ قُطِّعَتْ بِهِ ٱلْأَرْضُ أَوْ كُلِّمَ بِهِ ٱلْمَوْتَىٰ ۗ بَل لِّلَّهِ ٱلْأَمْرُ جَمِيعًا ۗ أَفَلَمْ يَا۟يْـَٔسِ ٱلَّذِينَ ءَامَنُوٓا۟ أَن لَّوْ يَشَآءُ ٱللَّهُ لَهَدَى ٱلنَّاسَ جَمِيعًا ۗ وَلَا يَزَالُ ٱلَّذِينَ كَفَرُوا۟ تُصِيبُهُم بِمَا صَنَعُوا۟ قَارِعَةٌ أَوْ تَحُلُّ قَرِيبًا مِّن دَارِهِمْ حَتَّىٰ يَأْتِىَ وَعْدُ ٱللَّهِ ۚ إِنَّ ٱللَّهَ لَا يُخْلِفُ ٱلْمِيعَادَ

And if there was any Qur’ān [i.e., recitation] by which the mountains would be removed or the earth would be broken apart or the dead would be made to speak,1 [it would be this Qur’ān], but to Allāh belongs the affair entirely. Then have those who believed not accepted that had Allāh willed, He would have guided the people, all of them? And those who disbelieve do not cease to be struck, for what they have done, by calamity - or it will descend near their home - until there comes the promise of Allāh. Indeed, Allāh does not fail in [His] promise.

كَذَّبَتْ ثَمُودُ وَعَادٌۢ بِٱلْقَارِعَةِ

Thamūd and ʿAad denied the Striking Calamity [i.e., the Resurrection].

ٱلْقَارِعَةُ

The Striking Calamity -

مَا ٱلْقَارِعَةُ

What is the Striking Calamity?

وَمَآ أَدْرَىٰكَ مَا ٱلْقَارِعَةُ

And what can make you know what is the Striking Calamity?
