Al Jathiyah, 18 Ayah
45:18
ثُمَّ جَعَلۡنَٰكَ عَلَىٰ شَرِيعَةٖ مِّنَ ٱلۡأَمۡرِ فَٱتَّبِعۡهَا وَلَا تَتَّبِعۡ أَهۡوَآءَ ٱلَّذِينَ لَا يَعۡلَمُونَ ١٨
Thumma Ja`alnāka `Alá Sharī`atin Mina Al-'Amri Fa Attabi`hā Wa Lā Tattabi` 'Ahwā'a Al-Ladhīna Lā Ya`lamūna
Then We put you, [O Muhammad], on an ordained way concerning the matter [of religion]; so follow it and do not follow the inclinations of those who do not know.
