The forms لَا تَتَّخِذُوا and لَا تَجْلِسْ prohibit actions. بَادِرُوا, اتَّقُوا, جَاهِدُوا, and اغْتَنِمْ direct action. A plural imperative often ends with وا, while اغْتَنِمْ addresses one person.
Recognizing the forms helps a learner distinguish what must be avoided from what is encouraged. Meaning still depends on context: غَرَضًا here is a target, الشَّمَاتَةَ is malicious delight, and فَرَاغَكَ means “your free time.” Grammar supports understanding rather than replacing it.
