Quran 6:56 from Surah Al-An'aam on Divine Marvels.
قُلۡ إِنِّي نُهِيتُ أَنۡ أَعۡبُدَ ٱلَّذِينَ تَدۡعُونَ مِن دُونِ ٱللَّهِۚ قُل لَّآ أَتَّبِعُ أَهۡوَآءَكُمۡ قَدۡ ضَلَلۡتُ إِذٗا وَمَآ أَنَا۠ مِنَ ٱلۡمُهۡتَدِينَ
English translation: Say Indeed I [I] am forbidden that I worship those whom you call from besides Allah Say Not I follow your (vain) desires certainly I would go astray then and not I (would be) from the guided-ones
Transliteration: qul inni nuhitu an a'buda alladhina tad'una min duni al-lahi qul la attabi'u ahwaakum qad dalaltu idhan wama ana mina al-muh'tadina
