Biography of the prophet muhammad illustrated classics

It was mentioned at the beginning that the book was written based on authentic information from islamic literature, like Quran & others.
My challange to the author: which part of the Quran portrays Muhammad the way it is mentioned in your book?
What authenticity did you follow to write this biography?
Biography of a person is a fact not a fiction, which you need to learn & realize first before attempting to write further.

Just having a Muslim name under authorship doesnt make one knowledgeable.

This author really has not done his research properly.
