And among them are (also) some who keep their ears towards you and (in view of their evil intentions) We have wrapped their hearts in veils. (So, it is not possible for them now) that they may understand it (the Qur’an) and (We have) plugged their ears. And even if they see all Signs (naked), they (still) will not believe in them, so much so that when they approach you and quarrel with you the disbelievers say (at that time): ‘This (Qur’an) is nothing but fabricated stories of the old folk.’
