Why Convert to Islam?
Under Islamic law, a man can generally have up to 4 wives. Personally I have found one too damn many for my liking.
Simply put, the man must prove he can provide for more than one wife.
The man is suppose to inform the first wife, but many Muslims do not follow this rule and there is no punishment if they don't, especially if they have permission from the ruling male of the woman's family, the father, if he is deceased, then the oldest brother, and if none, then her mother.
Also they still have pre-arranged marriages.
So if you have a daughter or son, you can have select breeding.
