﴿ وَيَعْبُدُونَ مِن دُونِ ٱللَّهِ مَا لَا يَمْلِكُ لَهُمْ رِزْقًۭا مِّنَ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ شَيْـًۭٔا وَلَا يَسْتَطِيعُونَ ﴾

“and will they [continue to] worship, instead of God, something that has it not within its power to provide for them any sustenance whatever from the heavens or the earth, and can do nothing at all?”

And they worship besides God that is other than Him what has no power to give them any sort of provision from the heavens such as water and the earth such as plants shay’an ‘anything’ is a substitute for rizqan ‘provision’ nor do they have the capacity nor are they able to do anything — and these are the idols.
