The broader category of non-declarative expression includes commands, prohibitions, questions, wishes, and related acts. Belonging to that category does not make all instances identical in meaning: agreement in type and relevance of purpose are distinct tests.
In «كُلُوا وَاشْرَبُوا وَلَا تُسْرِفُوا», the prohibition does not cancel the preceding permissions; it qualifies their exercise. Coordination unites complementary instructions serving one practical goal.
