﴿ وَمَا يَتَّبِعُ أَكْثَرُهُمْ إِلَّا ظَنًّا ۚ إِنَّ ٱلظَّنَّ لَا يُغْنِى مِنَ ٱلْحَقِّ شَيْـًٔا ۚ إِنَّ ٱللَّهَ عَلِيمٌۢ بِمَا يَفْعَلُونَ ﴾

“For, most of them follow nothing but conjecture: [and,] behold, conjecture can never be a substitute for truth. Verily, God has full knowledge of all that they do.”

And most of them in worshipping idols follow nothing but conjecture since they imitate their fathers therein; truly conjecture avails nothing against truth when what is sought is knowledge. Surely God is Knower of what they do and will requite them for it.
