Surah Al-Hajj (The Pilgrimage), Verse 71

وَیَعْبُدُوْنَ مِنْ دُوْنِ اللّٰهِ مَا لَمْ یُنَزِّلْ بِهٖ سُلْطٰنًا وَّمَا لَیْسَ لَهُمْ بِهٖ عِلْمٌ وَمَا لِلظّٰلِمِیْنَ مِنْ نَّصِیْرٍ ۟

Wa ya'budoona min doonil laahi maa lam yunazzil bihee sultaananw wa maa laisa lahum bihee 'ilm; wa maa lizzaalimeena min naseer

“Yet they worship, besides Allah, things for which no authority has been sent down to them, and of which they have (really) no knowledge: for those that do wrong there is no helper.”
