Surah Al-Hajj, ayah 12

22:12

يَدۡعُواْ مِن دُونِ ٱللَّهِ مَا لَا يَضُرُّهُۥ وَمَا لَا يَنفَعُهُۥۚ ذَٰلِكَ هُوَ ٱلضَّلَٰلُ ٱلۡبَعِيدُ ١٢

Yad'ū min dūnillāhi mā lā yadurruhū wamā lā yanfa'uhū dhālika huwad-dalālul-ba'īd

He invokes instead of Allāh that which neither harms him nor benefits him. That is what is the extreme error.
