Q:

I heard that Mormons are not considered People of the Book. Is this true, and if so, why is this? Mormons believe in the Bible and also uphold many traditional Christian values, so why would they not be characterized as People of the Book in the same way as other Christians and Jews?

A:
In the strictest sense of the word, People of the book is defined as Jews and Christians. It can also be inclusive of those that have followed legitimate books and prophets up until the final messenger for a given people.

This is where the problem occurs:

Mormons believe in a continual prophet as well as an ammended bible in comparison to the original torah and bible. Thus, such behavior functions as a breakawy away from the definiiotion of what is termed as ‘people of the book’ as per quran.
Allah Certainly Knows Best.

p.s. As muslims we apprecaite the similarities Mormons and Muslims share, however, the above is a respose as per religion Al-Islam.
