What do the letters placed above the verses mean?

Question:
She has another question, saying: There are some letters placed above the verses, so what do these letters mean? (M) and (J), and (Q) and (L) and (Y) connected to each other, and (S) and (L) and (Y) connected to each other. Did these letters come down with the verses, or did the scholars place them to teach the Quran reader where to pause in recitation?

Answer:
Some reciters placed these to teach the reader; they are not part of the Quran. Rather, some reciters placed them for instruction, to teach the reader how to pause. (M) is for the obligatory pause, (La) is for not pausing, and (J) is for the permissible pause. They intended them as a convention and clarified them in their books, the books of recitation in the books of tajwid. So review the books you have on this topic, and you will know their conventions. They are placed to guide the reader and teach him the appropriate and obligatory pauses. If you review their conventions, you will know this requirement, if Allah wills. Yes.
