The Holy Quran 6:123 — Surah Al-An'am
Arabic text
وَكَذَٰلِكَ جَعَلْنَا فِى كُلِّ قَرْيَةٍ أَكَـٰبِرَ مُجْرِمِيهَا لِيَمْكُرُوا۟ فِيهَا ۖ وَمَا يَمْكُرُونَ إِلَّا بِأَنفُسِهِمْ وَمَا يَشْعُرُونَ
Translation
Thus (as We have made sinners the prominent people of Makkah and current ringleaders) We made the prominent ones in every town the sinners so that they may plot there (to stop others from accepting Imaan and to involve them in sin). They plot only against themselves (because they will be punished for it) but they do not realise (understand) this.
