﴿وَلَا يَحِيقُ الْمَكْرُ السَّيِّئُ إِلَّا بِأَهْلِهِ﴾
Evil plotting surrounds none but those responsible for it. (Fāṭir 35:43)
Lā yaḥīqu expresses the occurrence of the consequence, al-makru al-sayyiʾu identifies the morally qualified act, and illā bi-ahlihi restricts the consequence to its perpetrators. Each element has an identifiable semantic role.
The passage illustrates how a clause may be measured by the meanings performed by its components, rather than by bare length.
