All mighty Allah [swt] has mention 14 unique individual letters combinations at the beginning of HIS 29 chapters of Al-Quran. And people called it Harf-e-Muqatta'at , but as far as I am sure I have not find any verses which indicate, Allah given this title / or such name as “Muqatta’at” more likely it became known through people saying which invented by their so-called scholar.
There is so many theories regarding those letters, which been propagated on every era, people has written so many books about them. I have mention some of them peoples theories below as example.

THEORY OF MUALANA MUHAMMAD ALI
Such opinion does not find favour among other classical commentators, because the possible combinations of letters are virtually infinite and the Attributes they represent seem to be chosen arbitrarily. However here it is how he concluded..
Alif (ا): an abbreviation for Ana (أنا, I am)
Ḥā (ح): an abbreviation for Al-Ḥamīd (الحميد, the Praised),
Rā (ر): an abbreviation for the Seeing,
Sīn (س): as either an abbreviation for Man or an abbreviation for As-Samī' (السميع, the Hearing),
Ṣād (ص): an abbreviation for As-Ṣādiq (الصادق, the Truthful),
Ṭā (ط): as either an abbreviation for the Benignant or an interjection equivalent to O (in dialect),
ʿAyn (ع): an abbreviation for Al-'Alīm (العليم, the Knowing),
Qāf (ق): an abbreviation for Al-Qādir (القادر, the Almighty),
Kāf (ك): an abbreviation for Al-Kāfi (كافي, the Sufficient),
Lām (ل): an abbreviation for Allāh (الله, using the second letter),
Mīm (م): as either an abbreviation for Al-'Alīm (العليم, the Knowing, using the ending letter) or for Al-Majīd (المجيد, the Glorious),
Nūn (ن): a word meaning Inkstand,
Hā (ه): as either an abbreviation for Al-Hādīy (الهادي, the Guide) or an abbreviation for Man (in dialect), and
Yā (ي): an interjection equivalent to O.
THEORY OF BOGUS RASHAD KHALIFA
According to him, these initials, which prefix 29 chapters of the Qur'an, occur throughout their respective chapters in multiples of nineteen. Some of his findings relating to Sura (Chapters) with initials (Muqatta'ats) are:
1. Between the first initialed sura (Sura 2) and the last initialed sura 68 there are 38 = 19 x 2 un-initialed suras 7
2. Between the first and last initialed sura there are 19 sets of alternating “initialed” and “uninitialed” suras.7
The reason I added BOGUS in front of his name “rashad khalifa” is because this guy claimed, he was new messenger and he use his mathematic code 19 as replacement of Sunni hadith which he reject . And most of all this liar rejected TWO beautiful verse form chapter 9 of al-Quran using proof from hadith, yet he say he don’t follow hadith and not only that this guy been charged with rape case, yet he think he was messenger of Allah, Was he not out of mind, haven’t got clue what he was talking about. and how Is it possible for a messenger of Allah to have such low character like him?
THEORY OF FAKHR AL-DIN AL RAZI
He mention multiple opinions that these letters present the names of the Surahs as appointed by God. In addition, he mentions that Arabs would name things after such letters (for example, 'money' as 'ع', clouds as 'غ', and fish as 'ن').
IMPORTANT VERES RELATED TO THIS SUBJECT
The Quran 3:7
It is He who has sent down to you, the Book; in it are verses [that are] precise - they are the foundation of the Book - and others unspecific. As for those in whose hearts is deviation, they will follow that of it which is unspecific, seeking discord and seeking an interpretation [suitable to them]. And no one knows its [true] interpretation except Allah. But those firm in knowledge say, "We believe in it. All [of it] is from our Lord." And no one will be reminded except those of understanding.
1. Do them so-called scholars or their blind follower are unable to understand the above crystal clear verse [3:7] ?
2. If not then why are they seeking interpretation of them verses which contain them unique letters?
3. As Allah indicated on above verse that those who in firm in knowledge do not do such act, Yet their scholar are busy interpreting therefore according to the verses they has deviation in their hearts, So why do those people follow them deceivers blindly ?
1. As Allah mention on 2:18 [Deaf, dumb, blind - and they cannot turn back] that’s why they don’t see this clear verses
2. They had to interpret and If they don’t, then the above verse will be wrong, therefore simply some of them have to do it. They also do it to show their blind follower that, they have great knowledge, so their follower don’t hesitate to worship them.
3. People have tendency on following guru’s and scholar so they will do it especially when Satan promise he will try to mislead mankind, Except them whom sincerely believe and trust on Allah alone.
Them so-called scholar or others will seek interpretation of them letters / verses, Otherwise the verse 3:7 will be wrong if no one dose it, therefore their such action also provide another proof of Al-Quran being the TRUTH.
Also since Allah indicate for us to avoid interpret, then it is best for us to leave them letters alone and just believe it as Allah’s revelation.
However there could be a clue on verse 15:87 which say prophet Muhammad [s] got Seven al-Mathani and the grand Quran. And there is some translator who translated this seven Al-Mathani as Seven Pairs instead of oft repeated, and since we see them letters are in total of 14 then is their any possible that their prediction is correct and the verse 15:87 is indicating to them unique letters ?
However I personally think Seven Al-Mathani is related to something outside of Al-Quran and since them letters are part of Al-Quran, therefore this verses 15:87 probably not indicating to them letters. However to understand my detail understanding on Al-Mathatni then please go to Al-Mathatni page, but I simply always just like to be silent on all of them particular issue, since only Allah knows best about them.
