Rejection of divine warnings

وَلَئِنْ أَخَّرْنَا عَنْهُمُ ٱلْعَذَابَ إِلَىٰٓ أُمَّةٍ مَّعْدُودَةٍ لَّيَقُولُنَّ مَا يَحْبِسُهُۥٓ ۗ أَلَا يَوْمَ يَأْتِيهِمْ لَيْسَ مَصْرُوفًا عَنْهُمْ وَحَاقَ بِهِم مَّا كَانُوا۟ بِهِۦ يَسْتَهْزِءُونَ

And if We hold back from them the punishment for a limited time, they will surely say, "What detains it?" Unquestionably, on the Day it comes to them, it will not be averted from them, and they will be enveloped by what they used to ridicule.

ٱقْتَرَبَ لِلنَّاسِ حِسَابُهُمْ وَهُمْ فِى غَفْلَةٍ مُّعْرِضُونَ

[The time of] their account has approached for the people, while they are in heedlessness turning away.

كَذَّبَتْ ثَمُودُ بِٱلنُّذُرِ

Thamūd denied the warning.
