Surah Al-An'am, ayah 116

وَإِن تُطِعۡ أَكۡثَرَ مَن فِي ٱلۡأَرۡضِ يُضِلُّوكَ عَن سَبِيلِ ٱللَّهِۚ إِن يَتَّبِعُونَ إِلَّا ٱلظَّنَّ وَإِنۡ هُمۡ إِلَّا يَخۡرُصُونَ ١١٦

Wa in tuti' akthara man fil-ardi yudillūka 'an sabīlillāhi in yattabi'ūna illaz-zanna wa in hum illā yakhrusūn

And if you obey most of those upon the earth, they will mislead you from the way of Allāh. They follow not except assumption, and they are not but misjudging.³³⁸
