Qur'ān 9:31 · At-Tawbah (التوبة)

ٱتَّخَذُوٓا۟ أَحْبَارَهُمْ وَرُهْبَـٰنَهُمْ أَرْبَابًۭا مِّن دُونِ ٱللَّهِ وَٱلْمَسِيحَ ٱبْنَ مَرْيَمَ وَمَآ أُمِرُوٓا۟ إِلَّا لِيَعْبُدُوٓا۟ إِلَـٰهًۭا وَٰحِدًۭا ۖ لَّآ إِلَـٰهَ إِلَّا هُوَ ۚ سُبْحَـٰنَهُۥ عَمَّا يُشْرِكُونَ

They have taken their scholars and monks as lords besides Allah, and [also] the Messiah, the son of Mary. And they were not commanded except to worship one God; there is no deity except Him. Exalted is He above whatever they associate with Him.
