Al-An'aam 6:25

There are some among them who listen to you[7], but We have placed covers on their hearts so that they do not understand it, and deafness in their ears. Even if they were to see every sign, they would still not believe in them. When they come to you arguing, the disbelievers say, “This is nothing but ancient fables.”

[7] When you recite the Qur’an.

And among them are those who listen to you,[300] 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."

[300] When you recite the Qur’ān.

25. 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."

Of them are some who listen unto thee, but We have placed upon their hearts veils, lest they should understand, and in their ears a deafness. If they saw every token they would not believe therein; to the point that, when they come unto thee to argue with thee, the disbelievers say: This is naught else than fables of the men of old.
