There is this practice in Islam where a man is allowed to marry 4 wives, provided he can love all of them equally.
Now tell me can a man love 4 women equally?
Secondly, when the man is tired of one or more of the wives, he divorces her/them and go again to equate the number to 4 and again divorces and marries more until he ends up marrying an uncountable number of women.
And for the woman so divorced, she is given a divorce certificate and off she goes and get married to another man. And if her new husband does not desire her any longer, he divorces her and she goes back to her first husband.
Methink that this thing called Islam give them enough room to go about promiscuiting. No wonder they marry them as soon as they come out from their mothers' womb and many of them end up with V.V.F so that they will keep on circulating from one man to the other
