Liar liar pants on fire! Let's look at the quran from an Islam site shall we?
http://www.islamicity.com/QuranSearch/ -here's my reference website.
33:50 O PROPHET! Behold, We have made lawful to thee thy wives unto whom thou hast paid their dowers,Asad(33,57)
[57] as well as those
whom thy right hand has come to possess from among the captives of war whom God has bestowed upon thee.Asad(33,58)
[58] And [We have made lawful to thee] the daughters of thy paternal uncles and aunts, and the daughters of thy maternal uncles and aunts, who have migrated with thee [to Yathrib];Asad(33,59)
[59] and any believing woman who offers herself freely to the Prophet and whom the Prophet might be willing to wed:Asad(33,60)
[60] [this latter being but] a privilege for thee, and not for other believers - [seeing that] We have already made known what
We have enjoined upon them with regard to their wives and those whom their right hands may possess.Asad(33,61)
[61] [And] in order that thou be not burdened with [undue] anxiety - for God is indeed much-forgiving, a dispenser of grace –
You see mr. messenger? Right hand posessions! In other words, Slaves! haha,
the quran does CONDONE slaves, and sex with slave girls.
that's where I've quoted it and that exactly how it is there.. anyone can browse through
