[Ali Imran]

This is a life of a playboy....and more women lining up to be his wives and concubines?
Would you be happy knowing that your daughter was one of his wives?
Your daughter can only find solace in money and material needs!
That's why it is wrong on all levels!

Concubines are not allowed in Islam. 

If my daughter is financially secure, why won't I be happy for her? She doesn't need to work. She can be a mother to her children. I'm sure she will be happy. Many women I know would want such a life.

The most satisfying job for a woman is raising her children. On top of that, she has a husband who would take care of her. That is where she can find solace when needed, which is gonna be rare.
