“To plot therein, but they plot not except against themselves, and they perceive [it] not” — that they are only plotting against themselves.

﴿وَكَذَلِكَ جَعَلْنَا فِي كُلِّ قَرْيَةٍ أكَابِر مجرميها﴾.
قَالَ محمدٌ: الْمَعْنَى: جَعَلْنَا فِي كُلِّ قَرْيَةٍ مُجْرِمِيهَا أَكَابِرَ. قَالَ قَتَادَة: وَمعنى (أكَابِر): جَبَابِرَةٌ.
﴿لِيَمْكُرُوا فِيهَا وَمَا يَمْكُرُونَ إِلَّا بِأَنْفسِهِم وَمَا يَشْعُرُونَ﴾ أَنَّهُمْ إِنَّمَا يَمْكُرُونَ بِأَنْفُسِهِمْ.
قَالَ محمدٌ: الْمَعْنَى: أَنَّ جَزَاءَ مَكْرِهِمْ راجعٌ عَلَيْهِم.
