Did the prophet Muhammad PBUH really die from poison? According to a Hadith this is true?

What does the Quarn say on this matter ?

As far as I know, nothing is mentioned on this matter

Here is some information from several sources.
There seems to be a huge difference in views, between Shia and sunni. (understandably so)

The Death of the Prophet (www.islaam.org.uk)
Islam Watch - "Did the Prophet Die While Making-Love to Aisha?" by Ayesha Ahmed
Death of Prophet Muhammad (632 AD)
