وَكَذَٰلِكَ جَعَلْنَا فِى كُلِّ قَرْيَةٍ أَكَٰبِرَ مُجْرِمِيهَا لِيَمْكُرُوا۟ فِيهَا ۖ وَمَا يَمْكُرُونَ إِلَّا بِأَنفُسِهِمْ وَمَا يَشْعُرُونَ
Thus have We placed leaders in every town, its wicked men, to plot (and burrow) therein: but they only plot against their own souls, and they perceive it not.
