Let President Obama now tell us whether he knows that the "Prophet of Islam" conducted massacres and mass enslavements.

In a speech at the U.N. on September 25, 2012, President Obama made the appalling statement that "the future must not belong to those who slander the Prophet of Islam."

Is the President aware that Islamic sources such as the "Sirat Rasul Allah" show that the so-called "Prophet of Islam," Muhammad, during his ten-year raiding career, committed cruel massacres (such as the massacre of the men of the Banu Quarayza), mass enslavements (such as that of the women and children of the Banu Quarayza, and of several other tribes), mass expulsions, and mass expropriations of land and property - and along the way, ordered many assassinations of people who had dared to speak out against him - such as the poet Asma bint Marwan?

Does the President know that emulation of Muhammad has brought genocide?
