What is the evidence in the saying of Allah the Exalted: “None touches it except the purified” that indicates that only one in a state of ritual purity may touch the mushaf?

Question:
May Allah reward you, Your Eminence, father. The questioner says regarding the saying of Allah the Exalted , some scholars say that the intended meaning of "the purified ones" in the noble verse is the angels, and if the intended meaning had been the condition of purity from ritual impurity, it would have said "the ones who have purified themselves."

Answer:
My brother, we have explained this. We said that they are the angels. "No one touches it except the purified ones" means the Preserved Tablet; no one touches it except the purified ones. However, there is a hint, a hint called the indication of the hint, that the mushaf is also not to be touched except by the purified ones from among the children of Adam, by way of the indication of the hint, not by way of the explicit text.
