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).

Quran's Stunning Numerical & Scientific Miracles.

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.

Here is the short answer:

From https://www.answering-christianity.com/blog/index.php/topic,3150.msg15747.html#msg15747:

Can anyone prove from bible that hazrat ismail (a.s.) was in Arab and Ibrahim (a.s.) was about to slaughter him?

Both the Bible and the Glorious Quran agree that:

1-  Ishmael's covenant was put on hold (pause) until the Jewish covenant comes to pass, and the latter generations come:

2-  Ishmael's name means the GOD finally heard the Prayer.  Ishmael's name is a great proof that he was the sacrificed son.  He was born after long decades of frustration and long waits.  He was born after a long time of decades of desperation.  Isaac would not have been that big of a deal relatively speaking, because Ishmael was already born, and the long horrid desperation was long gone.  And Ishmael at the time was his only son, and for a long time too.  Ishmael was 13 years older than Isaac.  Peace be upon them all.

The challenge wasn't just for Abraham to give up his son for GOD Almighty.  Any mere person can do this, even to pagan deities:

[006:137]  Even so, in the eyes of most of the pagans, their "partners" made alluring the slaughter of their children, in order to lead them to their own destruction, and cause confusion in their religion. If God had willed, they would not have done so: But leave alone them and their inventions.

While it was a test for Abraham to give up his son for GOD Almighty, but I believe it was also more of testing Abraham to give up what he longed for, and was desperate for, for many decades.  And it was also to honor Ishmael, the Prophet of Allah Almighty.  Peace be upon Abraham and his sons.

It matters not:

Let me make it absolutely clear that Islam does not stand and fall on:

(a)-  Whether Ishmael was the sacrificed-to-be son or not.
(b)-  Or whether Abraham and his children were Arabs or not.

None of this matters in Islam.  We are only presenting what the Glorious Quran confirms here.  If Isaac was the sacrificed son, then it wouldn't matter.  We still say Peace be upon all of Allah Almighty's Prophets and Messengers.  And Isaac was certainly one of them, and we love Isaac and revere him as much as Ishmael and all of Allah Almighty's Prophets.  Peace be upon them all.

And again, ethnicity has nearly no value in Islam:

[049:013] O mankind! We created you from a single (pair) of a male and a female, and made you into nations and tribes, that ye may know each other (not that ye may despise each other). Verily the most honoured of you in the sight of God is (he who is) the most righteous of you. And God has full knowledge and is well acquainted (with all things).

3-  The Jews' accounts and the Bible's credibility are a joke!  The Jews fabricated many lies.  Ironically, their accounts even admit this.

Quran Miracle: The Jews' and Christians' scribes changed and still change the Words.  Proven with images, text and videos from their corrupt bible and books!  See how they removed words and altered words.

As to Ishmael being an Arab, again, it matters not.  But if you care to know, Abraham, Ishmael and Isaac's father, was from Iraq.  Most Iraqis are Arabs.  Assyrians and others are a minority.  And even Assyrians and Kurds and others speak Arabic, and their bloods are mixed with Arabs.  Arabic had always been the dominant language in the Middle East and North and Central Africa for 20,000 years, if not even more.  And it's the language of the Holy Quran, Allah Almighty's Perfect and Miraculous Book with 1000s of Numerical and Scientific Miracles [1], and also Prophecies [2].  See literally the 1000s of STUNNING Miracles are listed here.  Also visit:

But again, it matters not to Islam what ethnicity Abraham was.

The following is the detailed answer....  

1-  Who was the sacrificed son?

Ishmael's Covenant was made for the latter generations according to both Islam and the Bible.  Let us look at Ishmael in great details:

Even in the altered Bible, there is strong evidence that support that Ishmael was the son to be sacrificed.  Ishmael's name means "GOD Heard", which implies:

•Ishmael was 13 years older than Isaac, and •Noble Verse 37:102 supports that Ishmael was a teenage boy:

  
Ishmael was put on PAUSE until the Covenant of the Israelites comes to an end:

3-  Abraham had no child for almost 100 years. He was completely barren:

Abraham was very desperate for a son.  Ishmael was the greatest gift from GOD Almighty to Abraham.  This is why Abraham named him GOD finally Answered my Prayer.  GOD Almighty put Abraham to the ultimate test by Commanding him to slaughter this precious son.  Abraham obeyed GOD Almighty by attempting to slaughter his son, Ishmael.  Ishmael too was true to his promise.  He never resisted, nor disobeyed.  He was willing to get slaughtered for the Will of Allah Almighty.  GOD Almighty saved Ishmael at the last minute, and Commanded Abraham to slaughter a ram instead.

4-  The corrupt Jewish books say it was Isaac:

But the name "ISHMAEL" really exposes their lies and gives it all away!  The name clearly suggests that Abraham was MOST DESPERATE with Ishmael, and hence, Ishmael's test would‘ve been FAR GREATER than Isaac's.  Isaac was the second son, and 13 years younger.  The Jewish Law gives double the inheritance to the OLDEST SON when the father dies (Deuteronomy 21:17). 

This is not a war between Ishmael and Isaac.  In Islam, we honor all of the people of Israel's Prophets and Messengers of GOD Almighty.  Peace be upon Abraham, Ishmael and Isaac. And peace be upon Hagar and Sara.  Again, please visit:

Again, please visit: Ishmael was put on pause until the Israelites' Covenant passes.  See slides 32-38.  Both the Bible and Glorious Quran agree on this.

"El" in names as in Ishmael was common among the Jews.  Is the GOD of Islam different?  Allah Almighty allowed for His Holy Name to be shortened as "El" in Ishmael, and Lillah for Li-Allah in the Quran, as in Alhamdulillah in both Islam and Judaism.

5-  Is Elohim Allah? [1, *] [2] [3]

The "im" in Hebrew is a majestic plural for GOD Almighty.  The root Word is "Eloh".  And the more original Jews such as Yemenites and others say Alohim or Alah-im.  And when you yourself pronounce it, you do naturally pronounce it with a double "l": Allah.  Jews do call Him: Allah-im.  Aramaic-speaking people also call GOD Almighty Allah.  See the following videos for Biblical references and proofs.  Also, pre-Islamic Biblical archeological findings have GOD Almighty as "Allah".  So the Original Holy Name for GOD Almighty is not Eloh.  It is Allah!  Eloh is a Hebrew dialect, which not all Hebrew speakers use anyway.  Allah had always been the Original and Universal GOD Almighty even before birth of Judaism, and the existence Hebrew.  And Hebrew is a developed language from Phoenician.  See the following links:
