Is there a documentation on Muhammad?

I asked this question in Interfaith Dialogue community:

Is there a non-islamic documentation on Muhammad during his living?
please don't bring sources after the year 632 AD.

Here are some responses to this question:

Shekhar:

Interesting. I never thought like that. Looking forward to some interesting information.

Zubia was the first muslim who tried to give an answer:

writing books or knowing how to read n write was not a norm these days. according to a source, there were only 17 ppl in Makkah who can read n write. in arab, the ppl in those times were simply illiterate.

So Zubia is aware of that there is no such documentation and try to explain why.

Then the discussion diverted to other places.

It was Jay who Explain my question far better than i did:

Friends purpose of this topic as I understood is to share the history of Arabia from a Pagans perspective ie perspective of victims of Islam.
As islam was the winner it would naturally demonise the pagans exactly the way British Historians demonised Indians and Muslim historinas demonised Hinduism/Sikh Gurus during Muslime rule in India.
Invaders and their associates always demonsie teh victims.
But there is always a perspective of the same event from a victims point of view.
Naturalyy muslims will glorify Mohammed and justify his every actions.
However there is a need to understand the same vent from a Pagan point of view.
Are there any contemporay sources that highlight pagans point of view about Mohammed and his mission.
After reading both points of views only we can know unbiased truth.
But unofrtunately muslim invaders in every part of teh world attacked temples , universities and libraries from taxshila to Nalanda and put the books on fire they hardly allowed any book avaialable other then Quran to surviwe due to simple reason.
Does this books anything better then Quran?
Yes it has : you are lying it is impossible . so get kileld and burn the book.
If it doesnt : then its not required. again burn it.
That's why Pre Islamic sources of history were destroyed completelt to make sure uninterrupted glorification of Mohamemd buy carrying out onesides propaganda.
That's why none here is able to bring even a single source of victims point of view.
I am amazed by Zubia's justification that there were all illeyral people except 17 in mecca those days. She never gave any reference of her information though? Is it a naturally biased Islamic source of some unbiased pre Islamic source?

Kamel also joined saying:

topic being documentation ON muhammed , by his contemporaries !
it is shown to NOT exist , and one wonders why !?
I mean its not like it is 3000 - 4000 years ago , surely the copts , the jews of that time , pagans , Zoroastrians , these are / were Arabia's neighbors.
NO ONE recorded anything ??

Khuldoon which is Muslim guy answered:

an account by a non-muslim upon prophet at that time, I dont know. havent heard of any.

So buttom line there's no such documentation,the question is why?
Is it cause in this time and area people weren't such developed to write such documents? or Is it cause muslims destroyed such documents?
