I just want to refer to your understanding of the Prophet Muhammad (PBUH).
How much do you know about the Prophet Muhammad ? Just read what these people has to say about the Seal of the Prophets.
He was Caesar and Pope in one; but he was Pope without Pope's pretensions. Caesar without the legions of Caesar; without a standing army, without a bodyguard, without a palace, without a fixed revenue. If ever any man had the right to say that he ruled by the right divine, it was Muhammad, for he had all the power without its instruments and without its supports.
-Bosworth Smith
Mohammad and Mohammadanism, London 1874, p 92
His readiness to undergo persecution for his beliefs, the high Moral character of the men who believed in him and looked up to him as leader, and the greatness of his ultimate achievement all argue his fundamental integrity. To suppose Muhammad an impostor raises more problems than it solves.Moreover, none of the great figures of history is so poorly appreciated in the West as Muhammad.

Mohammad At Mecca, Oxford, 1953. p 52
It is never ending what good things, most Educated and Broad-Minded non muslims have to say about the Prophet Muhammad (PBUH).
Just ponder, is it not incontrovertible proof of his prophethood that, despite being Unlettered and having led a Very Normal and Quiet Life for forty years, that all of Arabia stood in awe and wonder of his wonderful eloquence and oratory when he began to preach Islam? It was so matchless that legions of Arab poets, preachers and orators of the highest calibre failed to produce a composition that could compare with or equal it. And above all, how could he state scientific truths that would not be known by to the rest of humanity for centuries and that he could not learn about in any other way except through divine revelation?
Maybe people like you would say that it is not divine inspired but satan inspired. If common sense prevails, ask yourself what worldly possessions and luxuries did the Prophet enjoy during his time, if it was satan inspired. Zero is the answer !
In fact, The Prophet (PBUH) led an even harder life after gaining power and authority. To sum it up, hear his words when he was dying : 'We, the community of the Prophets, do not inherit. All that we leave is for Charity'. That is the Man, the Prophet(PBUH).
Go and do your homework well before passing any comments about him.
