116وَإِن تُطِعْ أَكْثَرَ مَن فِى ٱلْأَرْضِ يُضِلُّوكَ عَن سَبِيلِ ٱللَّهِ ۚ إِن يَتَّبِعُونَ إِلَّا ٱلظَّنَّ وَإِنْ هُمْ إِلَّا يَخْرُصُونَ
117إِنَّ رَبَّكَ هُوَ أَعْلَمُ مَن يَضِلُّ عَن سَبِيلِهِۦ ۖ وَهُوَ أَعْلَمُ بِٱلْمُهْتَدِينَ
[116-117] And O Muhammad if you obey most of the dwellers of the earth, they will lead you astray from Allah's Way, for they follow nothing but guess-work and indulge in mere conjectures.83 In fact, your Lord knows best those who have gone astray from His Way and also He knows those who are on the Right Path.
83The right thing for a seeker-after-truth is not to consider what way the majority of the people are following because that is based on guess-work instead of knowledge. Their beliefs, theories, philosophies, principles of life and laws are the result of guess-work and are, therefore, sure to mislead. In contrast to that, the way of life with which Allah is pleased, can only be the Way which Allah Himself has taught. Therefore, the seeker-after-truth should adopt that way and steadfastly follow it, even though he is left alone on it.
