سَيَقُولُ ٱلَّذِينَ أَشْرَكُوا۟ لَوْ شَآءَ ٱللَّهُ مَآ أَشْرَكْنَا وَلَآ ءَابَآؤُنَا وَلَا حَرَّمْنَا مِن شَىْءٍۢ ۚ كَذَٰلِكَ كَذَّبَ ٱلَّذِينَ مِن قَبْلِهِمْ حَتَّىٰ ذَاقُوا۟ بَأْسَنَا ۗ قُلْ هَلْ عِندَكُم مِّنْ عِلْمٍۢ فَتُخْرِجُوهُ لَنَآ ۖ إِن تَتَّبِعُونَ إِلَّا ٱلظَّنَّ وَإِنْ أَنتُمْ إِلَّا تَخْرُصُونَ
They who are idolaters will say: Had Allah willed, we had not ascribed (unto Him) partners neither had our fathers, nor had we forbidden aught. Thus did those who were before them give the lie (to Allah's messengers) till they tasted of the fear of Us. Say: Have ye any knowledge that ye can adduce for Us? Lo! ye follow naught but an opinion, Lo! ye do but guess.
Surah Al-An'aam(6:148)
