﴿ وَيَعْبُدُونَ مِن دُونِ ٱللَّهِ مَا لَا يَضُرُّهُمْ وَلَا يَنفَعُهُمْ وَيَقُولُونَ هَٰٓؤُلَآءِ شُفَعَٰٓؤُنَا عِندَ ٱللَّهِ ۚ قُلْ أَتُنَبِّـُٔونَ ٱللَّهَ بِمَا لَا يَعْلَمُ فِى ٱلسَّمَٰوَٰتِ وَلَا فِى ٱلْأَرْضِ ۚ سُبْحَٰنَهُۥ وَتَعَٰلَىٰ عَمَّا يُشْرِكُونَ ﴾

“and [neither will] they [who] worship, side by side with God, things or beings that can neither harm nor benefit them, saying [to themselves], "These are our intercessors with God!" Say: "Do you [think that you could] inform God of anything in the heavens or on earth that He does not know? Limitless is He in His glory, and sublimely exalted above anything to which men may ascribe a share in His divinity!"”

The last verse (17) emphasizes the subject conclusively by warning that attributing any statement to Allah Ta` ala that was not His Word, or denying what actually was, were crimes deserving severe punishment.
