Explanation

According to the Holy Quran: Allah has revealed the book and will protect it. 

Allah, the Almighty, says in the Quran: “Indeed, it is We who sent down the Quran, and indeed, We will be its guardian.” (Surah Al-Hijr, 15:9).

This verse is a testament to the divine promise that the Quran will remain unchanged and preserved in its original form.
