Q: Is having a Slave (girl) for sex nowdyas is allowed?
A: The LEGAL possession that a Muslim receives over a slave woman from the ?Ameerul-Mu'mineen? (the Islamic Head of State) gives him legal credence to have coition with the slave woman in his possession, just as the marriage ceremony gives him legal credence to have coition with his wife. In other words, this LEGAL POSSESSION is, in effect, a SUBSTITUTE of the MARRIAGE CEREMONY. A free woman cannot be 'possessed', bought or sold like other possessions; therefore Shariat instituted a 'marriage ceremony' in which affirmation and consent takes place, which gives a man the right to copulate with her. On the other hand, a slave girl can be possessed and even bought and sold, thus, this right of possession, substituting as a marriage ceremony, entitles the owner to copulate with her. A similar example can be found in the slaughtering of animals; that after a formal slaughtering process, in which the words, ?Bismillahi Allahu Akbar? are recited, goats, cows, etc.; become ?Halaal? and lawful for consumption, whereas fish becomes ?Halaal? merely through 'possession' which substitutes for the slaughtering.
