A.L.M (3:1)

[3:0] In the name of God, Most Gracious, Most Merciful
[3:1] A.L.M.*

God has the ability of humbling the reader with three simple letters: A.L.M. For 1400 years no one knew the meaning of these letters. With the advent of His messenger, God revealed the meaning of the letters to mankind. But even with this information the amount of information packed into these three simple letters is beyond our imagination.

A.L.M. (Alef Laam Mim)

The letters “A,” “L,” and “M” are the most frequently used letters in the Arabic language, and in the same order as we see in the Quranic Initials – “A,” then “L,” then “M.” These letters prefix six suras – 2, 3, 29, 30, 31, and 32 – and the total occurrence of the three letters in each of the six suras is a multiple of 19 [9899 (19×521), 5662 (19x 298), 1672 (19×88), 1254 (19×66), 817 (19×43), and 570 (19×30), respectively]. Thus, the total occurrence of the three letters in the six suras is 19874 (19x 1046), and the alteration of one of these letters destroys this phenomenon.
