I never said 1.4 MILLION...I said "1,40,000" or simply one hundred and forty thousand (at the time of his death..almost whole Mecca,Medina and many tribes were converted to Islam..weren't they?) If you still disagree with the number.. I can give you a source..
And rest of your post is filled with "beloved Prophet"...Thats why I wrote Muhammad..not Prophet Muhammad (S.A.W)..I tried to analyze Muhammad
as a historical figure..and I didn't use the world 'Politician'..I said "political leader"...Wasn't he the one who united Arabs under one banner for the first time in history? After which Arabs swept away the Persians and (east) Roman Empires? Who was the driving force behind the great Arab conquests
Try to see things in secular view...How are you saying that he wasn't a philosopher? How much influence does hadiths have on 1.8 billion people around the world? Just think for a moment...your life will definitely have influence of some hadiths...Hadiths are the sayings of Muhammad ! Philosophy is NOT "writing books" or "having student"
Ok it seems to me that what you want to do is disconnect Muhammed(pbuh) the man from Muhammed(pbuh) the prophet. If so then you must look to life of the Prophet (pbuh) before his nabowaat to see how influential he was in his community and elsewhere. All the achievements you mention, were made after he (pbuh) received the message and are the result of his nabowaat. Yes he has become a great example to many millions of Muslims around the world but that also is the command from ALLAH (SWT). I think he was one of if not the single most influential man to have walked the face of this earth but not because the reason you mention but because he was the final messenger of ALLAH (SWT) and the message of Islam is something only he could bare.
But as a group I would have to say the men and women who invented the internet. Hands down they win.
