Some of these (disbelievers pretend to) listen to you but We have put veils over their hearts (due to their own hard-heartedness) that they do not understand and there is heaviness in their ears (to listen to the truth). Even if they see every sign (of Ours), they would not believe therein: (their hard-heartedness has reached) such an extent that when they come to you, they dispute with you. Those who disbelieve say, `This (Qur'ân) is nothing but fables of the ancients.'
