Quran 10:18 Yunus, ayah 18 of 109

وَيَعْبُدُونَ مِن دُونِ ٱللَّهِ مَا لَا يَضُرُّهُمْ وَلَا يَنفَعُهُمْ وَيَقُولُونَ هَـٰٓؤُلَآءِ شُفَعَـٰٓؤُنَا عِندَ ٱللَّهِ ۚ قُلْ أَتُنَبِّـُٔونَ ٱللَّهَ بِمَا لَا يَعْلَمُ فِى ٱلسَّمَـٰوَٰتِ وَلَا فِى ٱلْأَرْضِ ۚ سُبْحَـٰنَهُۥ وَتَعَـٰلَىٰ عَمَّا يُشْرِكُونَ ۝١٨

10:18 They worship beside Allah that which neither hurteth them nor profiteth them, and they say: These are our intercessors with Allah. Say: Would ye inform Allah of (something) that He knoweth not in the heavens or in the earth? Praised be He and High Exalted above all that ye associate (with Him)!
