No, Muslims have the limit upto 4, not any more
Regarding giving privilage to women ... well ... Firstly you should realise, that man is more sexual than the woman. Biogically, a man can perform his duty as a husband, even after he has more than one wife… which a woman, if she has more than one husband, she will not be able to perform her duty, as a wife, enough and satisfactorily. Medical Science tells us that… ‘a lady… during her menstrual period, undergoes certain behavioral and psychological changes… in which she is mentally disturbed and therefore… the majority of the quar¬rels that take place are during the menstrual period.
Further if a man who has more than one wife, if he marries and if he has children, the identification of both the parents is possible - The father can be identified, and as well as the mother can be identified. In the other case, if a wife has more than one husband, you will only identify the mother, not the father. Islam gives utmost importance, to identification of the parents. And Psychologists tell us that… ‘If a child cannot identify his parents, he undergoes mental trauma’. No wonder the children of prostitutes, they have a very bad childhood. And if the child goes for admission in the school, and if he is asked… ‘What is the name of the father?’… You will have to give 2 names - and you know what the child is called.
