وَكَذَٰلِكَ جَعَلْنَا فِي كُلِّ قَرْيَةٍ أَكَابِرَ مُجْرِمِيهَا لِيَمْكُرُوا فِيهَا ۖ وَمَا يَمْكُرُونَ إِلَّا بِأَنْفُسِهِمْ وَمَا يَشْعُرُونَ 123
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.
