إِنْ هِيَ إِلَّا أَسْمَاءٌ سَمَّيْتُمُوهَا أَنْتُمْ وَآبَاؤُكُمْ مَا أَنْزَلَ اللَّهُ بِهَا مِنْ سُلْطَانٍ ۚ إِنْ يَتَّبِعُونَ إِلَّا الظَّنَّ وَمَا تَهْوَى الْأَنْفُسُ ۖ وَلَقَدْ جَاءَهُمْ مِنْ رَبِّهِمُ الْهُدَىٰ ٢٣
These are nothing but names which ye have devised,- ye and your fathers,- for which Allah has sent down no authority (whatever). They follow nothing but conjecture and what their own souls desire!- Even though there has already come to them Guidance from their Lord!
