The thing with the Muslims writer in general is that when they start writing about the life and deeds of the Prophet they are so much in awe of the personality that they can barely portray him as a normal human being. They somehow always end up creating an image which is so close to the divinity.
In this context, Martin Lings has been extraordinary. He not only describes the Prophet as the way he was, but do so most elegantly. That feeling of being in awe of the person is completely missing, and all for good. He tells the stories and the incidences in such beautiful manner that you hardly feel it is being said about a prophet. Even the miracles performed by the Prophet has been written in such simplicity that those seems to be the normal thing!
If there has ever been a book written about the Prophet to read at ease, it is this one!
