(146) I will turn away from My signs those who are arrogant upon the earth without right; and if they should see every sign, they will not believe in it. And if they see the way of consciousness, they will not adopt it as a way; but if they see the way of error, they will adopt it as a way. That is because they have denied Our signs and they were heedless of them.
(14) And [even] if We opened to them a gate from the heaven and they continued therein to ascend. (15) They would say, "Our eyes have only been dazzled. Rather, we are a people affected by magic.
(108) Those are the ones over whose hearts and hearing and vision Allah has sealed, and it is those who are the heedless. (109) Assuredly, it is they, in the Hereafter, who will be the losers.
(45) And when you recite the Qur"an, We put between you and those who do not believe in the Hereafter a concealed partition. (46) And We have placed over their hearts coverings, lest they understand it, and in their ears deafness. And when you mention your Lord alone in the Qur"an, they turn back in aversion.
(57) And who is more unjust than one who is reminded of the verses of his Lord but turns away from them and forgets what his hands have put forth? Indeed, We have placed over their hearts coverings, lest they understand it, and in their ears deafness. And if you invite them to guidance - they will never be guided, then - ever.
(200) Thus have We inserted disbelief into the hearts of the criminals. (201) They will not believe in it until they see the painful punishment.
(52) So indeed, you will not make the dead hear, nor will you make the deaf hear the call when they turn their backs, retreating. (53) And you cannot guide the blind away from their error. You will only make hear those who believe in Our verses so they are Muslims [in submission to Allah].
(58) And We have certainly presented to the people in this Qur"an from every [kind of] example. But, [O Muhammad], if you should bring them a sign, the disbelievers will surely say, "You [believers] are but falsifiers. (59) Thus does Allah seal the hearts of those who do not know.
(35) Those who dispute concerning the signs of Allah without an authority having come to them - great is hatred [of them] in the sight of Allah and in the sight of those who have believed. Thus does Allah seal over every heart [belonging to] an arrogant tyrant.
(63) Thus were those [before you] deluded who were rejecting the signs of Allah.
(44) And if We had made it a non-Arabic Qur"an, they would have said, "Why are its verses not explained in detail [in our language]? Is it a foreign [recitation] and an Arab [messenger]?" Say, "It is, for those who believe, a guidance and cure." And those who do not believe - in their ears is deafness, and it is upon them blindness. Those are being called from a distant place.
(23) Have you seen he who has taken as his god his [own] desire, and Allah has sent him astray due to knowledge and has set a seal upon his hearing and his heart and put over his vision a veil? So who will guide him after Allah? Then will you not be reminded?
