Quran 6:56 Al-An'am, ayah 56 of 165

قُلْ إِنِّى نُهِيتُ أَنْ أَعْبُدَ ٱلَّذِينَ تَدْعُونَ مِن دُونِ ٱللَّهِ ۚ قُل لَّآ أَتَّبِعُ أَهْوَآءَكُمْ ۙ قَدْ ضَلَلْتُ إِذًا وَمَآ أَنَا۠ مِنَ ٱلْمُهْتَدِينَ ۝٥٦

6:56 Say: I am forbidden to worship those on whom ye call instead of Allah. Say: I will not follow your desires, for then should I go astray and I should not be of the rightly guided.
