Surah Al-Jathiyah, Verse 18

ثُمَّ جَعَلۡنَٰكَ عَلَىٰ شَرِيعَةٖ مِّنَ ٱلۡأَمۡرِ فَٱتَّبِعۡهَا وَلَا تَتَّبِعۡ أَهۡوَآءَ ٱلَّذِينَ لَا يَعۡلَمُونَ١٨

thumma jaʿalnāka ʿalā sharīʿatin mina l-amri fa-ittabiʿ'hā walā tattabiʿ ahwāa alladhīna lā yaʿlamūna

Then We put you, [O Muḥammad], on an ordained way concerning the matter [of religion]; so follow it and do not follow the inclinations of those who do not know.
