(As for) those who disbelieve in Our communications, We shall make them enter fire; so oft as their skins are thoroughly burned, We will change them for other skins, that they may taste the chastisement; surely Allah is Mighty, Wise.

And of them is he who hearkens to you, and We have cast veils over their hearts lest they understand it and a heaviness into their ears; and even if they see every sign they will not believe in it; so much so that when they come to you they only dispute with you; those who disbelieve say: This is naught but the stories of the ancients.

And those who disbelieve say: Why has not a sign been sent down upon him from his Lord? You are only a warner and (there is) a guide for every people.

And certainly We have set forth for men every kind of example in this Quran; and if you should bring them a communication, those who disbelieve would certainly say: You are naught but false claimants.

And when a wave like mountains covers them they call upon Allah, being sincere to Him in obedience, but when He brings them safe to the land, some of them follow the middle course; and none denies Our signs but every perfidious, ungrateful one.
