What is the title of a reliable book, recognized by the schools of thought of Ahl al-Sunnah, that addresses their stance on the distortion of the Qur'an?

The Sunnis (Ahl al-Sunnah wal-Jama'ah) believe in the integrity of the Holy Quran from distortion, alteration, reduction, and augmentation. They consider any claim to such as an impugnment of Allah's promise to preserve it and a denigration of the Companions who compiled it. Furthermore, they deem anyone who alleges the distortion of the Quran to be an apostate. They substantiate this belief with the Almighty's saying: (Indeed, it is We who sent down the Dhikr [i.e., the Quran], and indeed, We will be its guardian) [Al-Hijr: 9]. Muslims have unanimously agreed that the recited Quran is the word of Allah and His revealed inspiration, and that anyone who intentionally omits a letter from it, or adds to it, or alters it, is an apostate. They emphasize that abrogation (naskh) is not considered distortion, and that any narrations among the Sunnis claiming distortion of the Quran are false and rejected, unlike other sects that may adopt such narrations.
