exposing the fallacy of predestination, said, 'If it were like this , the concepts of reward, Punishment, command, and prohibition would be erroneous. The meaning of promise [of Paradise] and threat [of the Hellfire] would be futile, and there would be no blame for a wrongdoer, nor praise for the good-doer. Furthermore, the good-doer would be more blameworthy than the wrongdoer, and the latter would deserve more praise than the former. This [i.e. predestination] is the claim of the idolators and the foes of the Merciful.'
