Futility of polytheism and idolatry

فَمَنْ أَظْلَمُ مِمَّنِ ٱفْتَرَىٰ عَلَى ٱللَّهِ كَذِبًا أَوْ كَذَّبَ بِـَٔايَـٰتِهِۦٓ ۚ أُو۟لَـٰٓئِكَ يَنَالُهُمْ نَصِيبُهُم مِّنَ ٱلْكِتَـٰبِ ۖ حَتَّىٰٓ إِذَا جَآءَتْهُمْ رُسُلُنَا يَتَوَفَّوْنَهُمْ قَالُوٓا۟ أَيْنَ مَا كُنتُمْ تَدْعُونَ مِن دُونِ ٱللَّهِ ۖ قَالُوا۟ ضَلُّوا۟ عَنَّا وَشَهِدُوا۟ عَلَىٰٓ أَنفُسِهِمْ أَنَّهُمْ كَانُوا۟ كَـٰفِرِينَ

And who is more unjust than one who invents about Allāh a lie or denies His verses? Those will attain their portion of the decree until, when Our messengers [i.e., angels] come to them to take them in death, they will say, "Where are those you used to invoke besides Allāh?" They will say, "They have departed from us," and will bear witness against themselves that they were disbelievers.

إِنَّ ٱللَّهَ يَعْلَمُ مَا يَدْعُونَ مِن دُونِهِۦ مِن شَىْءٍ ۚ وَهُوَ ٱلْعَزِيزُ ٱلْحَكِيمُ

Indeed, Allāh knows whatever thing they call upon other than Him. And He is the Exalted in Might, the Wise.
