One of the claims regarding the Quran is there is a checksum on it.

What is a checksum? Well it’s an integrity check, a way for an author to sign or “seal the envelope” in order to indicate that the message has not been tampered with. A very simple checksum would be for example if I put the total word count at the bottom of this article. When you get to the bottom you can see if the number matches the words in this article and you can confirm its correct. However this wouldn’t be very tamper proof as you could change all of the words and maintain the same number in order to still pass the checksum. A better checksum would be to assign each letter a value (A is 1, B is 2 and so on) and then put the total at the end. This would be better, but it’s still very weak as someone could tamper with it as long as they kept the same number of letter uses the same it would still pass the checksum. Nevertheless the point should be clear.

To claim that the Quran has a type of checksum on it is quite weak. Let’s take a look at one particular claim about the **Odd/Even Binary Miracle of the Quran** as described here:

Performing A Checksum On The Quran – Maths Miracle

If Allah was intending to make this a checksum or integrity check, wouldn’t there have been far more clear and better ways to do it?

# How impressive is this really?

First of all, why doesn’t the Quran simply have half the verses with odd number of ayat and half with even ayat? This would be impressive, especially if it was every other surah being odd/even.

Why do we have to add the Surah Number to the Number of Ayat to get this result (Lets call this “magic numbers”)? Seems arbitrary doesn’t it. Let’s just say it’s because “Allah” wanted us to make sure the correct Surah Number had the Correct # of Ayat, so you have to add them. Are we hunting for something here, or is this really the intention of the author? Not sure how we were expected to figure out that we need to add these two seemingly arbitrary numbers together, but okay, whatever, let’s grant that.

Second of all, there is no rhyme or reason or pattern to the magic numbers.

The first few: 8, 288, 203, 180, 125, 171…. They are not even in a pattern

If this was really Allah trying to give us a message, what would have been impressive is if the verse counts (or “magic numbers”) were in Fibonacci sequence, or the Golden Ratio, or Prime numbers…

Even in nature we are able to find such beautiful patterns appearing.

But instead we see no such thing just arbitrarily scattered numbers, half of which are odd and half of which are even. **Given that each magic number must be odd or even and randomly distributed, you would expect approximately 50% to be odd and 50% to be even anyway. It’s not that surprising.**

Do you think the supreme creator of the universe couldn’t come up with a better way to sign his final revelation and protect it from corruption? How about sending multiple identical copies to different Prophets – one to Australia, one to China, and one to the Middle East. Checkmate atheists.

Third of all, there is nothing amazing about **6555** and **6236**. They are just the totals we come up with. Which means that we don’t have to keep these totals, as long as if we change the ayah counts, the total remains.

## The problem is that this so-called checksum is vulnerable to severe modifications.

1. For any of the 57 totals that are even, you can go ahead and change the number of ayat in there to an arbitrary number. So for example for Surah 1, you can change the number of verses from 7 to 9, 11, 13, 15, 17, 19, 21, 23, etc…

You can do the same for Surah 2, but using even numbers: 286, 288, 300, 302, 306, …

**When you do this, you will modify the even total and the “checksum” is still intact.
**

2. You can shuffle around the surahs. Infact there are billions and billions of possible changes you can make to these numbers and still make it work out.

The conditions are that you need to swap the odd totals with other odd totals. For example, if you swapped the ayah count of Surah 1 (Fatiha) with Surah 6 (Al Anam) **both the 6555 and 6236 total will still match.**

If we break down the data into four groups, we have: odd surahs with odd number ayat, odd with even, even with odd, and even with even. So looking at the total number of swaps we can perform using a basic permutations calculator in excel

Type | Surahs | Unique Ayah Counts | Possible orderings |

OddOdd | 27 | 20 | 2.16049E+24 |

OddEven | 30 | 28 | 1.32626E+32 |

EvenOdd | 27 | 24 | 1.81481E+27 |

EvenEven | 30 | 25 | 2.21044E+30 |

That last column that says E+ means that is how many zeros are in the number.

So the first one is saying there are 2,160,490,000,000,000,000,000,000 possibilities

So there are *billions and billions and billions and billions* of possible combinations that would lead to the exact same **6555 and 6236 totals**.

This is not what you call a checksum. It’s just **begging the question. **

You can play along with the included Excel file and change the numbers to see how this works.

And I have published the source for a computer program that you can run that will shuffle the numbers or play around with my results.

**I have included a list of 1000 results with different ayah counts which still give the exact same 6555 and 6236 total. If someone runs this a million million times they will get a million million different results that still work.**

**Miracle? Hardly**

What do you think?

Err yeah sure that’s exactly what I was thinking lol. Bro I don’t know where you find the time to research this but it’s great work keep it up. We need people like you to take a pragmatic logical and commonsense approach to all issues religious to make transparent the fallacies of the Quran being of divine origin.

On my train commute. I have 2 hours a day 🙂

Love your work and the way you deliver it, lots of love

there is a Golden ratio in the distribution of chapter numbers and verse numbers

https://scontent.fcmb3-1.fna.fbcdn.net/v/t1.0-9/14639722_1760602870865876_4681701383556748837_n.jpg?oh=2237b3dec7dadb0c21050ae6d0017161&oe=592C8072

You truly seem to be obsessed with this. I would recommend letting it go now, both of us have made our points now.

Well you said it would be impressive if the surah totals were in a golden ratio and i showed u how they were if you take repeating totals divided by non repeating totals….. Anyways ill leave you with this video https://www.youtube.com/watch?v=bR3Ti2eLoFI

1.You can see Makkah is the golden ratio point of the world

2.the city of Makkahs golden ratio point is at the kaaba

3.original rectangular dimensions of the kaaba (with hatim) correspond to the golden ratio and they are also 2 consecutive prime numbers in the fibonachi sequence

4.many other golden ratio findings which an athiest should find interesting

its less than 2 hours so ideal for your commute

You spend so much energy on this? What about all the other issues in the Quran? Did you ever look into them? Its been two weeks and you are still responding to this. Honestly H…

Yet Muslims pray towards Mecca but on a round earth (the one created by this god character) clearly if you face ‘east’ you are actually facing straight out into space. On a sphere you can’t orientate yourself towards a particular compass point because you will always be going off on a tangent. So how come something as basic as this mathematically is overlooked, when claims for far more complex situations are presented?

So what do u propose we do? all face haphazardly in different directions?

or maybe pray with our faces on the floor?

i remember talking to a flat earther once…… he said if the earth were round how is it that with telescopes we can see regions of the earth we should not be able to see if the earth were round….

Obv he didnt understand gravity and how light bends…..

Dont take our facing of Mecca in our prayers so literal…..think of it as a way we unify the ummah…..

If you were to be so literal your next question may be if someone were to pray without a compass and turn a few inches more to a side than he should literally he would literally miss Mecca by miles

https://www.quora.com/What-is-the-golden-ratio-point-of-earth

No that has been debunked like all other quran ”miracles”

https://www.quora.com/What-is-the-golden-ratio-point-of-earth

It has been debunked like all quranic miracle claims of significance.

Offcourse ive come across the other so called issues… to me most are subjective …..ive researched them all throughout the years and am frankly bored of spending time on the same issues over and over….frankly im sure there are stuff ive come across that ud love to know as someone who speaks out against islam….i think you mentioned slavery in your latest video which is supposed to exist in islam with captives of war ONLY if at all…. but even with these issues a person who believes can interpret and rationalise them away or even embrace it… i mean its not something most will loose faith over and not everyone is motivated to embrace secular humanist values…

I glanced at your next article and you talked of imam ahmed and shafi and their views as if they are both infalliable in islam ….. i mean if you were a salafi as i heard u say you should already now how we tackle these issues… i spent loads of time on theology (aqeedah) and jurisprudence (fiqh) already so why start researching it again….

the fundamental difference between you and me i think is i spent years trying to understand Quranic arabic and trying to memorize the Quran with the meaning ….so id already experienced the miraculous patterns and structure of the Quran before i started researching all this stuff you seem to have issues with. So im firmly grounded… i mean maybe you were probably bored in taraweeh prayers, for me its like a 2 hour movie where the time just flies by in minutes…..

When i research a topic i like to do a thorough job and explore all angles of it which is why 2 weeks later im still on this topic. I chose to engage with you on this topic and honestly i hadnt spent alot of time on it before….. SInce your initial blog ive focused my free time on it, researching the mathematical wonders in the Quran and even literary wonders such as described in the work of Dr. Raymond Farrin as well as the 4 parts here https://www.youtube.com/watch?v=WfVfybIQzTU ….

it just so happens this is something that im interested in at the moment and ive learnt alot as a consequence of your blogs….so in a weird way ive kind of benefited from the exchange… Been busy with google earth these last few days as you probably might if you watch the video i sent before…..

The supposed miracle about the golden ratio in Surah+Versenumber is false. The golden ratio is 7905 and 4886 and not like the quran states 7906/4885. Is the Quran debunked now? Or does it change your percption since it would have been really easy to get a golden ratio there.

Abdullah, your analysis is missing the point that the checksum was unknown to any would-be modifications that someone would have attempted. Your working backwards now that you know the formula. The other thing ur missing is that if you make these changes while still respecting the formula, you are still breaking other checksums. It’s more intricate than your excel file in isolation.

exactly. he’s just trying to trick people. besides he used a computer and he didn’t write the quran using those random numbers because otherwise, it wouldn’t even make any sense

it works but that doesn’t mean anything. you used a computer and you already knew the formula. you seem to forget that the quran was revealed throughout a long period which would make this imposssible

1) Your calculation of the probability is wrong .. You would not expect to 57 odd 57 even numbers in a list of 144 numbers that are randomly distributed with probability %50.

The probability of seeing 57 odd and 57 even number is given by : C(144, 72) / 2^144 = % 0.06 .

2) What you do in second part is simply generating numbers that fit into the checksum formula. You can do this for any kind of checksum if you have the formula. It doesn’t mean anything. This does not invalidate that Qur’an has a checksum in any way.

3) Finally, note Qur’an 89/3 which says: And [by] the even [number] and the odd. So given that there exists a verse in which God swears to even and odd numbers, I would say it’s quite interesting to see this pattern.

i was searching for this..

thank you so much

thats brilliant
