Qur'an 6:116

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

“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.”
