And who is more wrongful of actions than he who has been reminded of Allah's evident signs and revelations and shuns them, forgetting what his unclean hands have committed! The fact is We enshrouded their hearts to preclude them from exercising intellectual power or understanding and struck them deaf that nothing that enages the intellect would come to their hearing. These are those whose hearts dare rise defiant against Allah. And if you invite them to accept the spirit of truth guiding into all truth, never shall they acknowledge Providence as their guide.
