It is not a surprise that the word "PROOF" (Bayyinah) in the Quran follows the same mathematical miracle (proof) of the Quran that is based on the number 19 as mentioned in sura 74.

At the age of 38, Dr R. Khalifa discovered that the number 19 is the foundation of the mathematical miracle of the Quran.

The momentous discovery that "19" is the Quran's common denominator of the Mathematical Miracle of the Quran became a reality in January 1974, coinciding with Zul-Hijjah 1393 A.H. The Quran was revealed in 13 B.H. (Before Hijrah). This makes the number of years from the revelation of the Quran to the revelation of its miracle (in 1974) 1393+13=1406 lunar years. 1406 = 19 X 74. The only time number 19 was mentioned in the Quran is in sura 74.

The correlation between 19X74 lunar years and 1974 solar years could not escape notice, especially with number 19 mentioned in sura 74.

Sura 98 is called "The Proof" (Al-Bayyinah). The word "Al-Bayyinah" (the Proof) is repeated in the whole Quran 19 times. This word "the Proof" is so important, since it enforces the purpose of the Mathematical Miracle of the Quran to represent the proof of the authorship of the Quran by Almighty God.

We would expect Sura 19 to carry some of these manifestations of this miracle that is built on number 19 as does the rest of the Quran.

1. Being the 19th Sura, God Almighty gave it the longest set of initials, consisting of five letters, K,H,Y,'A,S.
2. letter "K" occurs in sura 19 , 137 times, "H" occurs 175 times. "Y" occurs 343 times, "'A" occurs 117 times and "S" (Saad) occurs 26 times. Thus the total occurrence of the five letters is 137+175+343+117+26=798=19X42
3. Sura 19 has 98 verses and the word "God" is mentioned 8 times in this Sura. Number 98 is actually the gematrical (Numerical) value of the Arabic word "Al-Bayyinah" or the "Proof " in English.

"Al-Bayyinah" is the name of Sura 98 in the Quran. (Is this a coincidence). This Sura has 8 verses, another coincidence?!!. More significant is the fact that , the word "'Bayyinah" occurs in the Quran 19 times. One more coincidence?!!. Remember that the word "Bayyinah " in Arabic means the proof. That is exactly the function of the mathematical miracle of the Quran.

Remember also that God , the Omnipotent has no co-incidence in the Universe He created and control.

P.S. : Number 19 and 8 are very much related to one another. 19 is the 8th prime number. Prime numbers are those numbers that are divisible only by themselves and by number one, (2,3,5,7,11,13,17,19,...)

Both number 19 and number 8 were mentioned undefined in the Quran in 74:30 and 69:17.

(Notice that 74+30+69+17=190 or 19X10- )
