And thus We have placed within every city the greatest of its criminals to conspire therein. But they conspire not except against themselves, and they perceive [it] not.
The Saheeh International Quran Translation
وَكَذَٰلِكَ جَعَلْنَا فِى كُلِّ قَرْيَةٍ أَكَٰبِرَ مُجْرِمِيهَا لِيَمْكُرُوا۟ فِيهَا وَمَا يَمْكُرُونَ إِلَّا بِأَنفُسِهِمْ وَمَا يَشْعُرُونَAnd thus We have placed within every city the greatest of its criminals to conspire therein. But they conspire not except against themselves, and they perceive [it] not.
