Surah An-Najm, ayah 23

53:23

إِنۡ هِيَ إِلَّآ أَسۡمَآءٞ سَمَّيۡتُمُوهَآ أَنتُمۡ وَءَابَآؤُكُم مَّآ أَنزَلَ ٱللَّهُ بِهَا مِن سُلۡطَٰنٍۚ إِن يَتَّبِعُونَ إِلَّا ٱلظَّنَّ وَمَا تَهۡوَى ٱلۡأَنفُسُۖ وَلَقَدۡ جَآءَهُم مِّن رَّبِّهِمُ ٱلۡهُدَىٰٓ ٢٣

In hiya illā asmā'un sammaytumūhā antum wa ābā'ukum mā anzalallāhu bihā min sultānin in yattabi'ūna illaz-zanna wamā tahwal-anfusu walaqad jā'ahum mir rabbihimul-hudā

They are not but [mere] names you have named them - you and your forefathers - for which Allāh 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.
