Al-An'am 6:116

وَإِن تُطِعْ أَكْثَرَ مَن فِى ٱلْأَرْضِ يُضِلُّوكَ عَن سَبِيلِ ٱللَّهِ ۚ إِن يَتَّبِعُونَ إِلَّا ٱلظَّنَّ وَإِنْ هُمْ إِلَّا يَخْرُصُونَ

Wa-in tuṭiʿ akthara man fī l-arḍi yuḍillūka ʿan sabīli l-lahi in yattabiʿūna illā l-ẓana wa-in hum illā yakhruṣūna

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.
