Is there any god besides Allah?
The ayah confronts the claim of partners with Allah, declaring His perfection and transcendence above all that is associated with Him.
أَمْ لَهُمْ إِلَٰهٌ غَيْرُ اللَّهِ ۚ سُبْحَانَ اللَّهِ عَمَّا يُشْرِكُونَ
“Or do they have an Ilaah (deity or God) besides Allah? How perfect Allah is above all that they associate alongside Him”
The ayah confronts the claim of partners with Allah, declaring His perfection and transcendence above all that is associated with Him.
When Allah’s “Plot/Plan” reaches its conclusion and descends upon them, it becomes clear there is no refuge and no rescuer besides Him.
This directly challenges the imagined power of any other “god” to benefit or protect.
At the moment of punishment or trial, the futility of their false gods is exposed. None but Allah can save.
رَّبَّنَا اكْشِفْ عَنَّا الْعَذَابَ إِنَّا مُؤْمِنُونَ
When a warning punishment of smoke came, they pleaded to Allah to remove it, professing belief—yet after relief, they returned to Shirk and disbelief.
Those facing death at sea cry out to Allah alone and promise sincerity, but as soon as they are saved, they revert to Shirk and disbelief.
The question also strikes at their scheming against the Messenger ﷺ: is there any deity that can support their plots when the only true God brings His plan against them?
“Plot/Plan” — Allah’s decisive plan that, upon its conclusion and descent, exposes the futility of any reliance besides Him.
