6:148 The idolaters will say, 'Had Allah willed, neither we nor our fathers would have associated (idols), nor would we have forbidden anything.' As such, those who have gone before them belied until they tasted Our Might. Say, 'Have you any knowledge you can bring forth to us? You follow nothing but guessing and you are only speakers of conjecture.'
6:150 Say, 'Bring those witnesses of yours who can testify that Allah has forbidden this.' If they testify to it, do not testify with them, nor follow the wishes of those who belie Our verses, and disbelieve in the Everlasting Life and ascribe equals to their Lord.
