وَأَمَرَهُمْ بِطَاعَتِهِ وَنَهَاهُمْ عَنْ مَعْصِيَتِهِ
He commanded them to obey Him and forbade them from disobeying Him.
Clause structure: Amarahum and nahāhum are coordinated verbs with opposed functions: command toward obedience and prohibition away from disobedience. Bi and ʿan mark their respective objects.
Meaning and inference: Religious responsibility has both dimensions: performing commanded obedience and refraining from forbidden disobedience.
Limit of inference: Command and prohibition establish moral responsibility; they do not themselves make the servant a helplessly compelled agent.
