The One Wrapping Himself Up - 74:31 "We have appointed only angels as guardians of the Fire, and We have made their number (nineteen) a trial for the disbelievers, to convince those who have been given the Book, to strengthen the faith of those who believe, to remove the doubts of those who have been given the Book and those who believe, and for those in whose hearts is a disease and the disbelievers to say, "What does Allah mean by this example?"So Allah leads astray whom He wills and guides whom He wills. None knows the armies of your Lord except Himself. This (number) is a message to the people."
Some news and signs that show that the Qur'an is true will appear in the future:
Explained in Detail/41:53 We will show them Our signs (signs and proofs) in the horizons and within themselves until it becomes clear to them that it is the truth. Is it not enough that your Lord is a witness to everything?

The Prophets/21:37 Humans have been created hasty. I will show you My signs; so do not hurry.

The Arabic Letter Sad/38:88 And you will know its news after a time.
The Arabic Letter Sad/38:87 This is a message to the whole world.

The Ants/27:93 "Say, "To Allah is the praise; He will show you His signs and you will recognize them. Your Lord is not unaware of what they do."

The Cattle/6:66 "Your people have denied it, though it is the truth. Say: "I am not a guardian over you"."
The Cattle/6:67 There is a time for the fulfillment of every news. They will know in the future.

The Ants/27:82 When the time comes, We will bring forth for them a creature made of earth, and he will inform them that the people do not believe in Our signs and miracles.
The Ants/27:83 The day will come when We will gather and drive out from every community those who deny Our signs and Our miracles.
The Ants/27:84 "When they come, He will say: "Did you deny My signs and miracles when you did not comprehend them with your knowledge? Or what was it that you were doing?"

The Companies/39:23 Allah has sent down the best hadith in a coherent book in two parts. The skins of those who honor their Lord tremble because of it. Then their skins and hearts soften towards the message of Allah. This is Allah´s guidance; He guides whom He wills and/or guides whom He wills to it. There is no guidance for anyone whom Allah leads astray

The Moon/54:1 The Hour (the end of the world) is near and the moon has split.
The Moon/54:2 "If they see a miracle, they turn away and say, "It is a continuing magic"."
The Moon/54:3 They denied and followed their desires and the status quo.
The Moon/54:4 But the news has come to them, full of warnings to prevent their evil deeds.
The Moon/54:5 This is a superior wisdom, but the warnings do not avail.

The One Wrapping Himself Up/74:31 "We have appointed only angels as guardians of the Fire, and We have made their number (nineteen) a trial for the disbelievers, to convince those who have been given the Book, to strengthen the faith of those who believe, to remove the doubts of those who have been given the Book and those who believe, and for those in whose hearts is a disease and the disbelievers to say, "What does Allah mean by this example?"So Allah leads astray whom He wills and guides whom He wills. None knows the armies of your Lord except Himself. This (number) is a message to the people."

Ta-Ha/20:133 "They said: "He should have at least brought us a sign (a miracle)!"Did not the proof (evidence) in the previous Books come to them?"

Prophet Hud/11:17 Those who had before the Book of Moses as a guide and a mercy, but now have a clear proof from a witness from their Lord, they believe in it. Whichever group disbelieves in it, its place is the Fire. Have no doubt about it. It is a truth from your Lord. But the majority of the people do not believe.

The Sandhills/46:10 "Say, "Have you considered, what if it is from Allah and you opposed it and a witness from the Children of Israel saw the like of it and believed, but you turned away arrogantly? Surely Allah does not guide an unjust people."
The Sandhills/46:11 "Those who disbelieve will say to those who believe, "If it were a good thing, they would not have been ahead of us,"and they will say, "This is a myth,"because they cannot find a way to it."
