Sura al-Jāthiyah 45:18

ثُمَّ جَعَلْنَٰكَ عَلَىٰ شَرِيعَةٍ مِّنَ ٱلْأَمْرِ فَٱتَّبِعْهَا وَلَا تَتَّبِعْ أَهْوَآءَ ٱلَّذِينَ لَا يَعْلَمُونَ

thumma jaʿalnāka ʿalā sharīʿatin mina l-amri fa-ittabiʿhā wa-lā tattabiʿ ahwāʾa lladhīna lā yaʿlamūna

Then We put thee on the (right) Way of Religion: so follow thou that (Way), and follow not the desires of those who know not.
