Quran is only the religious
book on the face of the
earth that says Marry only
one as mention in chapter 4:3
but it also mention in same
chapter that Marry women of your choice two, three, or
four; but if you fear that
you shall not able to deal
justly with them, then
marry only one(4:3) At
another place it also mention that you are never able to
fair and judge as between
women (4:129) Conclusion@
Therefore polygamy is not a
rule but an exception, many
peoples are under the misconception that it is
compulsory for a Muslim
man to have more than one
wife. Broadly, Islam has five
categories of Do’s and Don’ts:
‘Fard’ i.e. compulsory or obligatory ‘Mustahab’ i.e.
recommended or
encouraged ‘Mubah’ i.e.
permissible or allowed
‘Makruh’ i.e. not
recommended or discouraged ‘Haraam’ i.e.
prohibited or forbidden
Polygyny falls in the middle
category of things that are
permissible. It cannot be said
that a Muslim who has two, three or four wives is a
better Muslim as compared
to a Muslim who has only
one wife. because naturally
no woman would like to
share a man, and sometimes. By nature males and females
are born in approximately
the same ratio. A female
child has more immunity
than a male child. A female
child can fight the germs and diseases better than the male
child. For this reason, during
the pediatric age itself there
are more deaths among
males as compared to the
females. During wars, there are more men killed as
compared to women. More
men die due to accidents and
diseases than women. The
average life span of females
is more than that of males, and at any given time one
finds more widows in the
world than widowers.
World female population is
more than male population I
don't want to list down county wise, but its true.
Thus, considering above
points normally women
have two option before a
woman who cannot find a
husband is to marry a married man or to become
public property. Islam
prefers giving women the
honourable position by
permitting the first option
and disallowing the second. There are several other
reasons, why Islam has
permitted limited polygyny,
but it is mainly to protect
the modesty of
women.treating them equally does not necessarily
mean making love with
them all the same number of
times each, giving them the
same amount of affection or
even loving each of them the same - it means that you
show respect to each of
your wives for the duty she
performs for you, regardless
of whether her role is
keeping the house, making babies or raising your
children.

Because a man's pehnis dies quickly with just one woman around him!
