THE
FIRST ATTRIBUTE OF ALLAH IS :
19 
The first relation between AlQur'an and Mathematics
In Mathematics, the basic numeral system is 1,2,3,4,5,6,7,8,and 9, where number 1 is the first number and number 9 is the last number. So we got 1 as the First, and 9 as the Last. So 19 is consist of the FIRST and the LAST number.
In AlQur'an, one of the verses about the
FIRST AND the LAST is surah 57:3
Bismillahirrahmanirrahiim,

" He is the FIRST and the LAST and the Manifest
and
the Hidden , and He is Knower of all things." (Qs:
57:3).
Please
visit here to see a complete surah 57 (Alhadid).
This is what Holy Prophet Muhammad
s.a.w explained about those the four attributes the Devine Being :
" Thou art the FIRST, so that there was nothing before Thee. And
Thou art the LAST, so there is nothing after Thee, and Thou art the Manifest, or The Ascendant over all, so that
there is nothing above Thee, and thou art the Hidden, the Knower of the hidden things, so that there is nothing hidden from
Thee".
In Arabic,The First = AWWAL, The Last = AKHIR, the Manifest = Zhahir, and the Hidden = Bathin and The Knower = 'Aliim.
Another translator translated Zhahir and Bathin as:
YUSUFALI: the Evident and the Immanent
PICKTHAL: Outward and the Inward
SHAKIR: the Ascendant (over all) and the Knower of hidden
things.
Here we have 2 couples of Devine Being of ALLAH.
Ist couple : AWWAL and AKHIR
Let us see the NUMERICAL
VALUE of the first COUPLE.
Awwal
Alif = 1, Wau = 6, Lam = 30
Awwal = 37 = 3 + 7 = 10 = 1 + 0 = 1 (the first)
Akhir
Alif = 1, Kha = 600, Ra = 200
Akhir = 801 = 8 + 1 = 9 ( the last ).
So we find, the sum of Numerical Value of:
Awwal = 1 or 1 represents AWWAL (the First).
Akhir = 9 or 9 represents AKHIR (the Last).
To represent those two of ALLAH's attributes, those two numbers must be connected.
If we connect these numbers, we will find a new number : 19

Another COUPLE is:
ZHAHIR (Manifest ) and BATHIN (Hidden)
Let us check the NUMERICAL VALUE of those two attributes of Divine Being.
Zhahir
Zha = 900, Ha = 5, Ra = 200
Zhahir = 1105 = 1+1+5 = 7
Bathin
Ba = 2, Tha = 9, Nun = 90
Bathin = 101 = 1+1 = 2
ZHAHIR and BATHIN represented by number 72
So, the 2 couples are:
1^{st} COUPLE = AWWAL
and AKHIR ( FIRST and LAST) represented by 19
2^{nd} COUPLE = ZHAHIR
and BATHIN (MANIFEST and HIDDEN) represented by 72
What will happen if we combine these 2 couples? They'll become 19
19 = 1+ 9 = 10 = 1 + 0 = 1
72 = 7 + 2 = 9
1972 = 1 + 9 + 7 + 2 = 19

We still have 1 more devine being.
Al 'ALIIM = THE KNOWER
NUMERICAL VALUE = 'Ayin, Lam, Ya', Mim = 7+30+10+40= 87.
What is the relation between 87 and 19?
If you open your AlQur'an, you will find surah
87 (Al A'laa) has
In ASMA al HUSNA, (99 names), ALLAH put His Devine Being Al 'Aliim in no. 19

How about the number of this surah (57: 3) ? is it related to 19?
57 : 3 = 19 !!
How consistent !!
57: 3 = 19 = 1 + 9 = 10 = 1 + 0 = 1
57 X 3 = 171 = 1 + 7 + 1 = 9
Again !! we find 1 and 9
 19
!!

Conclusion: In
MATHEMATICS or NUMERICAL WORLD , Number 19 represent "AWWAL,
AKHIR,
ZHAHIR,
BATHIN,
and 'ALIIM" or "the
FIRST, the LAST, the
MANIFEST, the
HIDDEN and the
KNOWER"
Thus 19 represent, "The UNLIMITED POWER OF ALLAH"  Regarding the number 19, 1 + 9 = 10 = 1+ 0 = 1 (Wahid / Tauhid ) 19 represent,  TAUHID is the main part of ISLAM. Thus, 19 represent,
Later
I will call 19
as
TAUHID SIGN Or
19 as
The First Attribute of ALLAH 
19 is not an ordinary number
19 is the most powerful number among the others.

To see how ALLAH SWT use 19 as the pattern of the His Creations.

By the name of ALLAH, I begin the Mathematical Miracle of ISLAM
The Mathematical Miracle of surah 57:3 (AWWAL, AKHIR, ZHAHIR and BATIN)
Found 12 Sept 2000
FACT 1
The Numerical Value :
AWWAL = 37, AKHIR = 108,
ZHAHIR = 1105, BATIN = 101.
The combination of Numerical Value :
AWWAL = 1, 6, 30, AKHIR = 1, 600, 200, ZHAHIR= 900, 5, 200, BATIN = 2, 9 ,90
Put all the numbers together
37 108 1105 101 1 6 30 1 600 200 900 5 200 2 9 90  isn't Multiple 19
The Combination of Num. Value of ALLAH = 130305
The Combination of Num. Value of MUHAMMAD = 408404
Put those number before the numbers
130305 408404 37 108 1105 101 1 6 30 1 600 200 900 5 200 2 9 90
= 19 x 68581793897037411107947980534737899476421210.0000
MULTIPLE 19!!
FACT 2
The Numerical Value :
AWWAL = 37, AKHIR = 108,
ZHAHIR = 1105, BATIN = 101.
37 108 1105 101 = 19 x 19530584479.0000
MULTIPLE 19!!
FACT 3
From the combination of Numerical Value (zeros were deleted)
1 + 6+ 3+ 1+6+ 2+ 9+ 5+ 2+ 2 + 9+ 9 = 55
From the Numerical Value :
37+ 108+ 1105+ 101=1351
55 +1351=1406 = 19 x 74
(note that the one and only word "NINE TEEN" in AlQur'an we can find in surah 74. The miracle of 19 was found in the year 1974)
FACT 4
From the combination of Numerical Value
1630+1600200+9005200+2990 =10610020
From the Numerical Value :
37+ 108+ 1105+ 101=1351
10610020 1351= 10608669= 19 x 558351.0000
FACT 5
From the Numerical Value :
37x 108x 1105x 101= 445973580 =4+4+5+9+7+3+5+8+0=45
From the combination of Numerical Value
1 6 30x1 600 200x900 5 200x2 9 90 = 7230606912648=7+2+3+0+6+0+6+9+1+2+6+4+8=54
45 + 54 = 99
(which is represent the 99 beautiful names of ALLAH)
FACT 6
The meaning of 19 we found in surah 57 : 3 .
The one and only word "NINE TEEN" we can find in surah 74 : 30
What will happen if you put all those numbers together?
57 3 74 30 = 19 x 301970.0000
MULTIPLE 19!!

What is another correlation between 57 : 3 and 19?
19 is PRIME NUMBER No.
8
Number 5, 7 and 3 are also Prime Numbers
5 = Prime Number No. 3
7 = Prime Number No. 4
3 = Prime Number No. 2
FACT 7
The MATHEMATICAL MIRACLE !!
