Peace and Salutations to all
Though no one knows about the meanings of these letters; we can extract some interesting patterns from these constructs. These patterns are not the meanings behind these letters, rather the patterns are a reflection of the beauty and potency of a bit of thought can determine from a mere combination of letters.
In the day of old when these were first revealed people didn’t hasten to ask Sayyiduna Muhammad (SAW) what these letters were for. They seemed to be shocked that he was uttering them in the first place.
The pronunciation of Alif - Aaa is a sound taken from the lowest part of the throat then we have Laam - L sound taken from the back of the molars in the mouth and then we have the letter Meem - M sound taken from the front with the lips clenched. The full range of the sounding of the letters extend from Alif to Meem relative to makhrij. i.e. all other letters fall within this range.
The ayah sounds when read as Alif-Laam-Meem which can be written down as ALF-LAM-MYM according to the names of those letters. We see that only two new letters have surfaced in on Alif the other in Meem, which are Fa and Ya.
Furthermore the Alif letter utilises all positions in the name Alif and Lam use only the second and the last mouth position and Meem uses on the last mouth position only.
The beginning is short with an abrupt Alif then we have two long length sounds the last one being slightly longer due to the mushaddad. The part when Laam merges with Meem there is an added length.
The words gradually creep up from a dark place to the most prominent feature of lips it is as though there is a process of progression from a place unknown working its way to the apparent.
This is just a pattern … in the spoken sound of Alif-Laam-Meem which then goes on to say “That is the Book in which there is no doubt, a guidance for …”
Bringing from darkness to light … from beginning to end … that is the Book in which there is no doubt.
