Surah Al-Haqqah, verse 6

كَذَّبَتْ ثَمُودُ وَعَادٌۢ بِٱلْقَارِعَةِ ﴿٤﴾

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

فَأَمَّا ثَمُودُ فَأُهْلِكُوا۟ بِٱلطَّاغِيَةِ ﴿٥﴾

So as for Thamūd, they were destroyed by the overpowering [blast].

سَخَّرَهَا عَلَيْهِمْ سَبْعَ لَيَالٍۢ وَثَمَـٰنِيَةَ أَيَّامٍ حُسُومًۭا فَتَرَى ٱلْقَوْمَ فِيهَا صَرْعَىٰ كَأَنَّهُمْ أَعْجَازُ نَخْلٍ خَاوِيَةٍۢ ﴿٧﴾

Which He [i.e., Allāh] imposed upon them for seven nights and eight days in succession, so you would see the people therein fallen as if they were hollow trunks of palm trees.

فَهَلْ تَرَىٰ لَهُم مِّنۢ بَاقِيَةٍۢ ﴿٨﴾

Then do you see of them any remains?
