Is Islam true?

If you married your maid servant, then she would be your wife, wouldn't she? Why would she need to be mentioned separately?

Good reasoning, however, know that even after marrying, a slave maid would remain slave until manumitted. That is the reason the punishment of adultery by such married maid wives is prescribed half that of free wife.

AhmadJoyia wrote: When it is settled that the phrase 'that their right hands possess' can't imply concubine, then the use of this phrase in this translation is only understood as 'your married maid servant/slave'. Therefore your assertion of 'Including sexual services?' are through marriage only.

According to the dictionary definition of concubine may be a legal or social inferior, but she is not an actual possession, so I agree it would not be a good translation. However, the same can be said about "maid servant".

AhmadJoyia wrote: Same as when you pay someone, you 'own/posses' his services.

Those who were "rightfully possessed" were not paid. They were captured in war, and then bought and sold as property. There are so many examples of this it's hard to know where to start, but here is an especially charming one where Muhammad himself sells a slave who would otherwise have been freed:
"A man decided that a slave of his would be manumitted after his death and later on he was in need of money, so the Prophet took the slave and said, "Who will buy this slave from me?" Nu'aim bin 'Abdullah bought him for such and such price and the Prophet gave him the slave."
Bukhari, vol. 3, Book 34, Number 351

More so, if s/he resides with you, you 'own/posses' more than her/his just services.

Including sexual services?
"Successful indeed are the believers...who guard their modesty -
Save from their wives or the (slaves) that their right hands possess..." (Quran 23:1-6, Pickthal translation)

No you do not.

Not unless you are being exploitive.
