The Plot of the Mischief-Makers and the End of the People of Thamud

Allah tells us about the evildoers of Thamud and their leaders who used to call their people to misguidance and disbelief, and to deny Salih. Eventually they killed the she-camel and were about to kill Salih too. They plotted to let him sleep with his family at night, then they would assassinate him and tell his relatives that they knew nothing about what happened to him, and that they were telling the truth because none of them had seen anything. Allah says:

وَكَانَ فِى الْمَدِينَةِ

لَنُبَيِّتَنَّهُ وَأَهْلَهُ ثُمَّ لَنَقُولَنَّ لِوَلِيِّهِ مَا شَهِدْنَا مَهْلِكَ أَهْلِهِ وَإِنَّا لَصَادِقُونَ

We shall attack him (Salih علیہ السلام) and his family at night, then will say to his heir, We did not witness the destruction of his family and we are really truthful - 27:49.
