Self-deception despite knowledge

وَعَادًا وَثَمُودَا۟ وَقَد تَّبَيَّنَ لَكُم مِّن مَّسَـٰكِنِهِمْ ۖ وَزَيَّنَ لَهُمُ ٱلشَّيْطَـٰنُ أَعْمَـٰلَهُمْ فَصَدَّهُمْ عَنِ ٱلسَّبِيلِ وَكَانُوا۟ مُسْتَبْصِرِينَ

And [We destroyed] ʿAad and Thamūd, and it has become clear to you from their [ruined] dwellings. And Satan had made pleasing to them their deeds and averted them from the path, and they were endowed with perception.
