Ahmed Raza Khan: Mohammed Aqib Qadri:
The polytheists will now say, “Had Allah willed, we would not have ascribed partners (to Him) nor would have our forefathers, nor would we have forbidden anything”; similarly those before them had denied, till the time they tasted Our punishment; say, “Do you have any knowledge so you can offer it to us? You follow only assumptions and only make guesses.”

Yusuf Ali:
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."

Pickthal:
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.
