How do we reconcile the statement that the entire Qur'an is comprehensible with the statement of some scholars regarding the disjointed letters: "Allah knows best"?

Question:
He says: Honorable Shaykh, may Allah grant you success, how do we reconcile the statement that the entire Qur'an is comprehensible to those addressed with the statement of some scholars that the disjointed letters at the beginning of the surahs are a matter of "Allah knows best" regarding their intended meaning? How is that possible?

Answer:
The letters are not words; they are letters only, letters only, disjointed letters. They are not words with meaning. A letter alone has no meaning until it is joined with others. That is why the grammarians say that speech is of three types: a noun, a verb, and a particle that comes for a meaning. A letter alone conveys nothing; when it is combined, it becomes a word. It becomes a word that indicates something. This is the meaning of the disjointed letters. Yes.
