Y. S. (Yaa. Seen.)
Y.
S.

These two letters prefix chapter 36. The letter "Y" (yaa) occurs in this chapter 237 times, while the letter "S" (Seen) occurs 48 times. The total of both letters is 285, 19x15. It is noteworthy that the letter "Y" is written in the Quran in two forms; one is obvious and the other is subtle. The subtle form of the letter may be co nfusing to those who are not thoroughly familiar with the Arabic language. A good example is the word "Araany" which is mentioned twice in 12:36. The letter "Y" is used twice in this word, the first "Yaa" is subtle and the second "Yaa" is obvious. chapter 36 does not contain a single "Yaa" of the subtle type. This is a remarkable phenomenon, and one that does not normally occur in a long chapter like chapter 36. In his book QURAN: VISUAL PRESENTATION OF THE MIRACLE (Islamic Productions, 1982) every "Yaa" and "Seen" in chapter 36 is marked with a star.
