Some ignorant from the Muslims claim that the Number 19 Miracle Noble Verses are a warning for those who try to believe in them and/or try to research them:

www.answering-christianity.com/100_percent_guarantee_that_quran_is_divine.htm

They used the following underlined points & question in Noble Verse 74:31:

1-  Fixed their number as a trial for unbelievers.
2-  What symbol doth God intend by this?

[074:030]  Overit are Nineteen  عليهاتسعة عشر.   
[074:031] And We have set none but angels as Guardians of the Fire; AND WE HAVE FIXED THEIR NUMBER ONLY وماجعلنا عدتهم الا     as (1) a trial for Unbelievers فتنة للذين كفروا,- (2) in order that the People of the Book may arrive at certainty, (3) and the Believers may increase in Faith,- (4) and that no doubts may be left for the People of the Book and theBelievers, (5) and that those in whose hearts is a disease and the Unbelievers may say, "What symbol doth God intend by this? ماذا اراد الله بهذا مثلا" Thus doth God leave to stray whom He pleaseth, and guide whom He pleaseth: and none can know the forces of thy Lord, except He and this is no other than a warning to mankind.   
[074:032] Nay,verily: By the Moon,
[074:033] And bythe Night as it retreateth,
[074:034] And bythe Dawn as it shineth forth,-
[074:035] Thisis but one of the MIGHTY ONES (Miracles)  انهالاحدى الكبر.
[074:036] Awarning to mankind,-
[074:037] To any of you thatchooses to  press forward,or to follow behind;-

They claim that the above two points are proof that this Miracle works against those who believe in It, and does not work in their favor.  It is a curse upon those who try to prove that there is a Number 19 Miracle:

ماذا اراد الله بهذا مثلا:

But the blasphemers are those who reject this Noble Miracle, which Allah Almighty said that it is one of the Mighty Miracles:

[074:035] Thisis but one of the MIGHTY ONES (Miracles)  انهالاحدى الكبر.
[074:036] Awarning to mankind,-
[074:037] To any of you thatchooses to  press forward,or to follow behind;-

Mosquito Example:

Not only that, but ماذا اراد الله بهذا مثلا (what does God mean by this example?) in the Glorious Quran refers to the disbelievers mocking and joking about the Miracles of Allah Almighty, and speaking arrogantly against them:

‏2:26 ان الله لايستحيي ان يضرب مثلا ما بعوضة فما فوقها فاما الذين امنوا فيعلمون انه الحق من ربهم واما الذين كفروا فيقولون ماذا اراد الله بهذا مثلا يضل به كثيرا ويهدي به كثيرا ومايضل به الا الفاسقين

[002:026]  Verily, Allah is not ashamed to set forth a parable even of a mosquito or so much more when it is bigger (or less when it is smaller) than it. And as for those who believe, they know that it is the Truth from their Lord, but as for those who disbelieve, they say: "What did Allah intend by this parable?" ماذا اراد الله بهذا مثلا  By it He misleads many, and many He guides thereby. And He misleads thereby only those who are Al-Fasiqoon (the rebellious, disobedient to Allah).

It is the arrogant and mocking and laughing and arrogantly dismissing disbelievers who ask this question.  Not the genuine believers.

Advice to every anti-Quran Muslim:

Stop being the enemy of the Glorious Quran.  I advise you to humble yourself more, declare your innocence to Allah Almighty from the cult that you belong to, and take the Miracles of the Holy Quran very very seriously.  You mislead the Ummah, you bray like a donkey (as Allah described you in the Quran), and like the people of Noah, you laugh at the Miracles and Warnings of Allah Almighty that were made for your generation today.

Prophet Noah vs. Rashad Khalifa:

It is very interesting that Prophet Noah, peace be upon him, is the cornerstone of this Noble Miracle.  Not the dajjal Rashad Khalifa.  See the Noble Verses for ample details here:

www.answering-christianity.com/100_percent_guarantee_that_quran_is_divine.htm

Do not be a braying donkey like Prophet Noah's doomed people were.  This is very serious, because this is Allah Almighty's Miracle to you, today, as the people of old before you also received their Miracles and laughed at them.

Will say this about you:

Prophet Muhammad, peace be upon him, will say this about you:

‏25:30 وقال الرسول يارب ان قومي اتخذوا هذا القران مهجورا

[025:030]  And the messenger will say, “My Lord, truly my people had forsaken this Qur’an.”

The doomed-to-Hell enemies of Islam, from the Muslims and infidels, have nothing but noise on the Glorious Quran.  To Hell with all of them.

Take care,

Here are some of my favorite Stunning Numerical and Scientific Miracles in the Glorious Quran that are listed in the main sections, below:

1-  The root for message and all of its derivatives, such as messenger and others occurs 513 times throughout the Glorious Quran.  The Prophets' and Messengers', peace be upon them, actual names (Muhammad, Moses, Noah, Abraham, Lot etc....) were also all combined mentioned 513 times in the Glorious Quran.  The detailed breakdown of all of this is thoroughly listed here.

Coincidence?  See 1,000s of examples! [1] (zip file).
  

2-  The Great Miracle.  Allah Almighty in the Holy Quran called the Number 19 Miracle "One of the Mighty Ones (Miracles)" (74:30-37) [1] [2].  See the 100s of Noble Verses that clearly testify to this Great Miracle.  Also, did you know that Allah Almighty Said in Surat Nuh (that's Noble Chapter Nuh (Noah)) that Prophet Noah lived for 950 years among his people. 

Yet, all Praise and Glory are due to Allah Almighty Alone, the entire Noble Surah is exactly written in 950 Letters [1] [2]!  You can thoroughly see this in the scanned images that thoroughly verify every single Noble Letter, in the links.  Click on the links to see the many other Numerical Miracles in the Holy Quran.  Also, see the Numerical Miracles section along with all of the other great sections.  Also, 1,000s of examples in zip & PDF (fonts) files all demonstrated in this article.

  
3-  19 X 115 = 2185 Number 19 and BASMALA Miracle.  The total numerical value of Noble Verses 74:30-37 themselves, which are the heart of the Number 19 Miracle, has a stunning Miracle in it.  The value of these Noble Verses matches the multiplication of the BASMALA's number of letters (19 Letters) and their total numerical values (115): 19 X 115 = 2185.  The Basmala, which full text in Arabic means "In the Name of Allah The Most Beneficent, The Most Merciful" is the Key to the Glorious Quran.  It is recited first before reading the Holy Quran, and it is also obligatory upon every Muslim to start with the Basmala before starting any task.  Again, 1,000s of examples in zip & PDF (fonts) files all demonstrated in this article.
  

4-  The Glorious Quran has 114 Chapters. The sum of those Chapters is 6555 (1+2+...+114 = 6555). There are also 6236 Noble Verses in the Glorious Quran. Now, if you add each Chapter's number with the number of its Verses, then you get a list of numbers. So 1 (first Chapter) + 7 (# of its Verses) = 8.  Do this for all Chapters.

1-  The sum of the odd numbers from the list = 6555.
2-  The sum of the even numbers from the list = 6236.

See the XLS file for 100% confirmation.  Also, see the ample STUNNING Numerical Miracles in the Glorious Quran, with 1,000s of examples! [1] (zip file).

5-  Please also checkout the many hundreds (1,000s) of Great Numerical Miracles, and the many tens (10s) of other Great Scientific Miracles:

  
For example:

1-  The explosion of the Universe, Galaxies and Stars bring about Smoke.
  
"When the sky disintegrates, and turns rose colored like paint (وردة كالدهان)." (The Noble Quran, 55:37) [2] [3]
  

The Glorious Quran declares that the earth is spherical: [1]
  

Allah Almighty in the Glorious Quran said that earth is:        -  Spherical: "egg-shaped" [1].        -  Is rotating around itself.        -  Is moving in space in curvy orbits [2].        -  Is in constant motion.        -  Is suspended in space.        -  Is swimming in space.        -  Is traveling through the constantly expanding universe [3].        -  The sunsetless North Pole miracle in the Glorious Quran [4].  At the top of the North Pole, the sun never sets, and I showed the video for that, and also quoted the scientific sources for that. Also in the lands near by, it almost never sets either, and I quoted sources for that as well, and also showed pictures of the "polar night" skies on these lands.        -  The Glorious Quran also speaks about many earths [5] and not just earth.        -  The Glorious Quran predicts 11 planets in our solar system [6].

  
This is also all demonstrated in good details in the following video file and articles:
