وَلَا إِلٰهَ غَيْرُهُ.
There is no deity other than Him.
وَاعْبُدُوا اللَّهَ وَلَا تُشْرِكُوا بِهِ شَيْئًا.
Worship Allah and do not associate anything with Him. (al-Nisāʾ 4:36)
How the passages fit: Affirming that none besides Allah is truly worthy of worship requires exclusive devotion in practice. Confessing oneness while directing worship elsewhere is inconsistent.
Application: Affirming divine lordship is important, but exclusivity must also govern acts of worship. The nature of a particular act still needs examination before calling it worship.
Limit of inference: This reasoning does not make every lawful human request or ordinary assistance into worship.
