Is it permissible for a student to write some verses in the margins of the mushaf?

Question:
May Allah reward you, Your Eminence, father. The questioner asks: Is it permissible for a student to add some verses to the margin of the tafsir that you mention, since the first type of tafsir is interpreting the Qur'an with the Qur'an?

Answer:
No, nothing is ever done in the mushaf. It is a book in which one does not make changes or act as one pleases. As for the mushaf, no, one does not mess with it, write in it, or write in its margins. Yes.
