In the Name of God, Most Gracious, Most Merciful  The word
"Proof"/"Bayyinah" in Quran and its miracle  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"
