7:43We will remove whatever rancor is in their hearts. Rivers will flow beneath them. And they will say, “Praise be to God, who has guided us to this. Had God not guided us, we would never be guided. The messengers of our Lord did come with the truth.” And it will be proclaimed to them, “This is the Garden you are made to inherit, on account of what you used to do.”

7:100Is it not guidance for those who inherit the land after its inhabitants, that if We willed, We could strike them for their sins? And seal up their hearts, so that they would not hear?

7:101These towns—We narrate to you some of their tales. Their messengers came to them with the clear signs, but they would not believe in what they had rejected previously. Thus God seals the hearts of the disbelievers.

7:179We have destined for Hell multitudes of jinn and humans. They have hearts with which they do not understand. They have eyes with which they do not see. They have ears with which they do not hear. These are like cattle. In fact, they are further astray. These are the heedless.
