22:71
وَيَعْبُدُونَ مِن دُونِ ٱللَّهِ مَا لَمْ يُنَزِّلْ بِهِۦ سُلْطَٰنًۭا وَمَا لَيْسَ لَهُم بِهِۦ عِلْمٌۭ ۗ وَمَا لِلظَّٰلِمِينَ مِن نَّصِيرٍۢ
And they worship besides Allah that for which He has not sent down authority and that of which they have no knowledge. And there will not be for the wrongdoers any helper.

Tafsir
Ibn Kathīr (abridged)
The Idolators' worship of others besides Allah and Their vehement rejection of the Ayat of Allah
Allah tells us that the idolators, in their ignorance and disbelief, worship besides Allah others which He has sent down no authority for, i.e., no proof or evidence for such behavior. This is like the Ayah:
وَمَن يَدْعُ مَعَ اللَّهِ إِلَـهَا ءَاخَرَ لاَ بُرْهَانَ لَهُ بِهِ فَإِنَّمَا حِسَابُهُ عِندَ رَبِّهِ إِنَّهُ لاَ يُفْلِحُ الْكَـفِرُونَ
(And whoever calls upon, besides Allah, any other god, of whom he has no proof; then his reckoning is only with his Lord. Surely, the disbelievers will not be successful.) 23:117 So Allah says here:
مَا لَمْ يُنَزِّلْ بِهِ سُلْطَـناً وَمَا لَيْسَ لَهُمْ بِهِ عِلْمٌ
(for which He has sent down no authority, and of which they have no knowledge;) meaning, they have no knowledge in the subject that they fabricate lies about; it is only something which was handed down to them from their fathers and ancestors, with no evidence or proof, and its origins lie in that which the Shaytan beautified for them and made attractive to them. Allah warned them:
