6:123 · Al-An'aam
وَكَذَٰلِكَ جَعَلْنَا فِي كُلِّ قَرْيَةٍ أَكَابِرَ مُجْرِمِيهَا لِيَمْكُرُوا فِيهَا ۖ وَمَا يَمْكُرُونَ إِلَّا بِأَنْفُسِهِمْ 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.
