Surah An-Naml — Ayah 50

وَكَانَ فِى ٱلْمَدِينَةِ تِسْعَةُ رَهْطٍ يُفْسِدُونَ فِى ٱلْأَرْضِ وَلَا يُصْلِحُونَ

And there were in the city nine family heads causing corruption in the land and not amending [its affairs].

قَالُوا۟ تَقَاسَمُوا۟ بِٱللَّهِ لَنُبَيِّتَنَّهُۥ وَأَهْلَهُۥ ثُمَّ لَنَقُولَنَّ لِوَلِيِّهِۦ مَا شَهِدْنَا مَهْلِكَ أَهْلِهِۦ وَإِنَّا لَصَـٰدِقُونَ

They said, "Take a mutual oath by Allah that we will kill him by night, he and his family. Then we will say to his executor, 'We did not witness the destruction of his family, and indeed, we are truthful.' "

فَٱنظُرْ كَيْفَ كَانَ عَـٰقِبَةُ مَكْرِهِمْ أَنَّا دَمَّرْنَـٰهُمْ وَقَوْمَهُمْ أَجْمَعِينَ

Then look how was the outcome of their plan - that We destroyed them and their people, all.

فَتِلْكَ بُيُوتُهُمْ خَاوِيَةًۢ بِمَا ظَلَمُوٓا۟ ۗ إِنَّ فِى ذَٰلِكَ لَـَٔايَةً لِّقَوْمٍ يَعْلَمُونَ

So those are their houses, desolate because of the wrong they had done. Indeed in that is a sign for people who know.
