Al-An'am 6:148

Sayaqoolu allatheena ashrakoo law shaaAllahu ma ashrakna wala abaonawala harramna min shay-in kathalikakaththaba allatheena min qablihim hattathaqoo ba/sana qul hal AAindakum min AAilminfatukhrijoohu lana in tattabiAAoona illa aththannawa-in antum illa takhrusoon

Those who associated [others] with Allāh will say, "If Allāh 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 misjudging."

Those who associate partners with Allah will say, “Had Allah willed, we would have not associated (partners with Him), nor our fathers, nor would we have made anything prohibited.” In the same way those who went before them gave the lie to (the truth) until they tasted Our punishment. Say, “Do you have any sure knowledge that you may produce to us? You follow nothing but whims, and do nothing but make conjectures.
