Futility of shirk (polytheism)

إِنَّ هَـٰٓؤُلَآءِ مُتَبَّرٌ مَّا هُمْ فِيهِ وَبَـٰطِلٌ مَّا كَانُوا۟ يَعْمَلُونَ

Indeed, those [worshippers] - destroyed is that in which they are [engaged], and worthless is whatever they were doing."

وَمَا كَانَ لَهُم مِّنْ أَوْلِيَآءَ يَنصُرُونَهُم مِّن دُونِ ٱللَّهِ ۗ وَمَن يُضْلِلِ ٱللَّهُ فَمَا لَهُۥ مِن سَبِيلٍ

And there will not be for them any allies to aid them other than Allāh. And whoever Allāh sends astray - for him there is no way.
