Before Islam, polygamy was considered normal and lacked any rules or limitations. As one of man’s essential needs, Islam has limited it, giving it specific conditions and terms. Islamic laws are all based on true needs and the benefit of society as a whole. The following needs are undeniable in a society where people live in:
1- Men are a lot more prone to death than women are, that being a result of wars and other incidents that take place for them.
2- Men’s sexual urge lasts longer than women’s.
3- During their menstrual period and some of the time that they are pregnant, women aren’t allowed to have any intercourse, while men never have any prohibition in their lives whatsoever.
4- There are always women who for whatever reasons have lost their husbands, and in the case of the prohibition of polygamy, they usually have to remain widows for the rest of their lives.
These factors cause an imbalance between men and women, and in order for society to stay healthy, there are three things that can be done:
a) Men must be satisfied with only one wife, and widows need to stay widows for the rest of their lives and suppress all of their inner needs and feelings.
b) Men can only have one lawful wife, but can also have illegitimate sexual relationships with other women who have lost their husbands.
c) Men who have the ability to manage more than one wife, without any financial, physical or moral problems coming up, and can be just towards all of their wives and children, are permitted to marry more than one wife.
Out of the three, Islam has chosen the third. Also, there are many reasons behind why Islam doesn’t allow polygamy for women, such as:
1- Such a matter is in complete contrast with the nature of women.
2- The health of the future generation will be endangered.
3- The real parents of many children will be mixed up and unknown, and many other reasons.
