Hot Debate! Christian Prince vs Egyptian Muslim on ''mut'ah'': PART 2

The second part of a 4 part discussion/debate on mut’ah: Renting Muslim women for sex. The debate gets heated over the meaning of the word nikkah as applied to mut’ah in the Quran. The Muslim insists Christian Prince is just playing a semantics game in order to mislead people. If nikkah means marriage, can you marry slaves who are already married? (Qur’an 4:24). ‘’Renting a woman for sex in Islam is the ultimate degradation of women and humanity’’ (Richard Carl Silk). There is no dignity in such a practice, in the present or when it was first commanded by Allah during the time of Muhammad prophet of Islam?
