وَاعْبُدُوا اللَّهَ وَلَا تُشْرِكُوا بِهِ شَيْئًا
Worship Allah and associate nothing with Him.
Worship establishes a positive command, while associate nothing forbids partnership in devotion. Together they express tawḥīd al-ulūhiyyah: worship is reserved for Allah.
The verse concerns worship itself. Recognizing a creature’s limited human capacities is not automatically the act of worship; the decisive issue is the divine right that may not be assigned to another.
