سَيَقُولُ الَّذِينَ أَشْرَكُواْ لَوْ شَاء اللّهُ مَا أَشْرَكْنَا وَلاَ آبَاؤُنَا وَلاَ حَرَّمْنَا مِن شَيْءٍ كَذَلِكَ كَذَّبَ الَّذِينَ مِن قَبْلِهِم حَتَّى ذَاقُواْ بَأْسَنَا قُلْ هَلْ عِندَكُم مِّنْ عِلْمٍ فَتُخْرِجُوهُ لَنَا إِن تَتَّبِعُونَ إِلاَّ الظَّنَّ وَإِنْ أَنتُمْ إَلاَّ تَخْرُصُونَ
[6:148]
Those who are polytheists will say: If Allah had pleased we would not have associated (aught with Him) nor our fathers, nor would we have forbidden (to ourselves) anything; even so did those before them reject until they tasted Our punishment. Say: Have you any knowledge with you so you should bring it forth to us? You only follow a conjecture and you only tell lies.
Those who give partners (to Allah) will say: "If Allah had wished, we should not have given partners to Him nor would our fathers; nor should we have had any taboos." So did their ancestors argue falsely, until they tasted of Our wrath. Say: "Have ye any (certain) knowledge? If so, produce it before us. Ye follow nothing but conjecture: ye do nothing but lie."
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.
