Surah Al-Jathiyah, ayah 18

45:18

ثُمَّ جَعَلۡنَٰكَ عَلَىٰ شَرِيعَةٖ مِّنَ ٱلۡأَمۡرِ فَٱتَّبِعۡهَا وَلَا تَتَّبِعۡ أَهۡوَآءَ ٱلَّذِينَ لَا يَعۡلَمُونَ ١٨

Thumma ja'alnāka 'alā sharī'atim minal-amri fattabi'hā walā tattabi' ahwā'al-ladhīna lā ya'lamūn

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.
