Concise Quran Commentary
It was as if they had never lived in their land in comfort and ease. Certainly, Thamūd disbelieved in Allah, their Lord, and so they remain outcasts from His mercy.
كَأَن لَّمْ يَغْنَوْا۟ فِيهَآ ۗ أَلَآ إِنَّ ثَمُودَا۟ كَفَرُوا۟ رَبَّهُمْ ۗ أَلَا بُعْدًا لِّثَمُودَ
as though they had never lived there. Indeed, Thamūd denied their Lord; so away with Thamūd!
