Quran 6:106 from Surah Al-An'aam on Divine Marvels.
ٱتَّبِعۡ مَآ أُوحِيَ إِلَيۡكَ مِن رَّبِّكَۖ لَآ إِلَٰهَ إِلَّا هُوَۖ وَأَعۡرِضۡ عَنِ ٱلۡمُشۡرِكِينَ
English translation: Follow what has been inspired to you from your Lord (there is) no god except Him and turn away from the polytheists
Transliteration: ittabi' ma uhiya ilayka min rabbika la ilaha illa huwa wa-a'rid ani al-mush'rikina
