In order to do so, it is necessary to understand two basic principles it has established in this regard. Firstly, it regards the institution of family as the basis of its social order. Secondly, it gives great importance to freedom in decision making by the man and woman who intend to marry. Both of them need some elaboration. Islam regards the institution of family as the basic unit of a society and stresses that it is the need of every individual if his life is viewed as a whole.
Man is basically a weak and an insecure being.
He has spiritual as well as material needs. Just as he needs to develop a strong relationship with the Almighty to fulfil his spiritual needs, he also needs to develop a strong relationship with his fellow human beings to fulfil his material needs. Islam says that a man and a woman must come together in a permanent bond of wedlock to create a family to fulfil these material needs which may be physical, emotional and psychological. A man and a woman taken separately, are incomplete in their existence. Both need each other to fill the voids of their personalities.
