وَأَمَّا ثَمُودُ فَهَدَيْنَٰهُمْ فَٱسْتَحَبُّوا۟ ٱلْعَمَىٰ عَلَى ٱلْهُدَىٰ فَأَخَذَتْهُمْ صَٰعِقَةُ ٱلْعَذَابِ ٱلْهُونِ بِمَا كَانُوا۟ يَكْسِبُونَ
And as for Thamud, We gave them guidance, but they preferred blindness to the guidance, so the bolt of the doom of humiliation overtook them because of what they used to earn.
