And among them are those who listen to you, but We have placed over their hearts coverings, lest they understand it, and in their ears deafness. And if they should see every sign, they will not believe in it. Even when they come to you arguing with you, those who disbelieve say, "This is not but legends of the former peoples."

Among them are some who [appear to] listen to you, but we have placed covers over their hearts- so they do not understand the Quran- and deafness in their ears. Even if they saw every sign they would not believe in them. So, when they come to you, they argue with you: the disbelievers say, ‘These are nothing but ancient fables,’

And of them there are some who listen to you; but We have set veils on their hearts, so they understand it not, and deafness in their ears; and even if they see every one of the Ayât (proofs, evidence, verses, lessons, signs, revelations, etc.) they will not believe therein; to the point that when they come to you to argue with you, the disbelievers say: "These are nothing but tales of the men of old."
