Surah Al-Furqan 25:55

وَيَعْبُدُونَ مِن دُونِ ٱللَّهِ مَا لَا يَنفَعُهُمْ وَلَا يَضُرُّهُمْ ۗ وَكَانَ ٱلْكَافِرُ عَلَىٰ رَبِّهِۦ ظَهِيرًا

But they worship rather than Allāh that which does not benefit them or harm them, and the disbeliever is ever, against his Lord, an assistant [to Satan].

Translation: Saheeh International

Tafsir

And they the disbelievers worship besides God that which neither benefits them when they worship it nor harms them should they refrain therefrom — and these are idols; and the disbeliever is ever a partisan against his Lord an assistant to Satan through his obedience to him.
