Verse 23

إِنْ هِىَ إِلَّآ أَسْمَآءٌ سَمَّيْتُمُوهَآ أَنتُمْ وَءَابَآؤُكُم مَّآ أَنزَلَ ٱللَّهُ بِهَا مِن سُلْطَـٰنٍ إِن يَتَّبِعُونَ إِلَّا ٱلظَّنَّ وَمَا تَهْوَى ٱلْأَنفُسُ وَلَقَدْ جَآءَهُم مِّن رَّبِّهِمُ ٱلْهُدَىٰٓ

These are nothing but names that you have made up, you and your ancestors when God never authorized them. They only guess and they only follow their desires when indeed guidance had come to them from their Lord.
