6:148

سَيَقُولُ الَّذِينَ أَشْرَكُوا لَوْ شَاءَ اللَّهُ مَا أَشْرَكْنَا وَلَا آبَاؤُنَا وَلَا حَرَّمْنَا مِن شَيْءٍ كَذَٰلِكَ كَذَّبَ الَّذِينَ مِن قَبْلِهِمْ حَتَّىٰ ذَاقُوا بَأْسَنَا قُلْ هَلْ عِندَكُم مِّنْ عِلْمٍ فَتُخْرِجُوهُ لَنَا إِن تَتَّبِعُونَ إِلَّا الظَّنَّ وَإِنْ أَنتُمْ إِلَّا تَخْرُصُونَ

Transliteration:

Sayaqoolu allatheena ashrakoo law shaa Allahu ma ashrakna wala abaona wala harramna min shay-in kathalika kaththaba allatheena min qablihim hatta thaqoo ba/sana qul hal AAindakum min AAilmin fatukhrijoohu lana in tattabiAAoona illa alththanna wa-in antum illa takhrusoona

Word by Word:

Will say those who associate partners (with Allah), "If Allah had willed, not we (would) have associated partners (with Allah) and not our forefathers and not we (would) have forbidden [of] anything." Likewise denied those who (were) before them until they tasted Our wrath. Say, "Is with you [of] any knowledge then produce it for us? Not you follow except the assumption, and not you (do) but guess."

Translations:

THOSE who are bent on ascribing divinity to aught beside God will say, "Had God so willed, we would not have ascribed divinity to aught but Him, nor would our forefathers [have done so]; and neither would we have declared as forbidden anything [that He has allowed]." Even so did those who lived before them give the lie to the truth -until they came to taste Our punishment! Say: "Have you any [certain] knowledge which you could proffer to us? You follow but [other people's] conjectures, and you yourselves do nothing but guess."

Those who give partners (to God) will say: "If God 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.

Those who are polytheists say: If Allah pleased we would not have set up (aught with Him) nor our fathers, nor would have made anything unlawful. Thus did those before them reject (the truth) until they tasted Our punishment. Say: Have you any knowledge so you would bring it forth to us? You only follow a conjecture and you only tell lies.

Those who associated with Allah will say, "If Allah had willed, we would not have associated [anything] and neither would our fathers, nor would we have prohibited anything." Likewise did those before deny until they tasted Our punishment. Say, "Do you have any knowledge that you can produce for us? You follow not except assumption, and you are not but falsifying."
