"a man can only have four wives..."<quoted text>
a man can only have four wives, and his wives must know, it cannot be a secret, and with his wives he must treat them equally, like if he buys one something he needs to buy the rest the same thing or at least for the same amount(price). if he does not meet up to this standards then he will pay for extreme torment in the hereafter. its not a joke, there are consequences, majority of Muslims do not go for four wives, for this reasons... who wants to be damned in hell?
as for adultery its punishable by death. if they cheat.
they do not only bring shame, but the children will suffer mentality for their parent's deviancy
Since there is roughly a 50/50 split between men and women, a man who has 4 wives implies that 3 men will not be able to marry.
Just what do you think those 3 men will be doing if they aren't busy taking care to protect a home and children?
