وَيَعْبُدُونَ مِن دُونِ ٱللَّهِ مَا لَمْ يُنَزِّلْ بِهِۦ سُلْطَٰنًۭا وَمَا لَيْسَ لَهُم بِهِۦ عِلْمٌۭ ۗ وَمَا لِلظَّٰلِمِينَ مِن نَّصِيرٍۢ
And they worship instead of Allah that for which He hath sent down no warrant, and that whereof they have no knowledge. For evil-doers there is no helper.
Surah Al-Hajj(22:71)
