النجم — An-Najm Ayat 23
اِنْ هِيَ اِلَّآ اَسْمَاۤءٌ سَمَّيْتُمُوْهَآ اَنْتُمْ وَاٰبَاۤؤُكُمْ مَّآ اَنْزَلَ اللّٰهُ بِهَا مِنْ سُلْطٰنٍۗ اِنْ يَّتَّبِعُوْنَ اِلَّا الظَّنَّ وَمَا تَهْوَى الْاَنْفُسُۚ وَلَقَدْ جَاۤءَهُمْ مِّنْ رَّبِّهِمُ الْهُدٰىۗ
In hiya illā asmā'un sammaitumūhā antum wa ābā'ukum mā anzalallāhu bihā min sulṭān(in), iy yattabi‘ūna illaẓ-ẓanna wa mā tahwal-anfus(u), wa laqad jā'ahum mir rabbihimul-hudā.
"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."
