Surah An-Najm · Ayah 23

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

In hiya illaaa asmaaa'un sammaitumoohaaa antum wa aabaaa'ukum maaa anzalal laahu bihaa min sultaan; inyyattabi'oona illaz zanna wa maa tahwal anfusu wa laqad jaaa'ahum mir Rabbihimul hudaa

They are not but [mere] names you have named them - you and your forefathers - for which Allah has sent down no authority. They follow not except assumption and what [their] souls desire, and there has already come to them from their Lord guidance.
