Among them are: The basic factor for the growth of society is the general natural law of marriage. The instinctive structure of man and woman represents this law. Both, man and woman are the main factors for the growth of social life. This instinctive relationship between man and woman is based on love and mercy. So, it leads to tranquillity. For this reason, the Holy Qur'an regards woman as the base of tranquillity.

That happens through the psychological and social tranquillity of man and of social life in general. That is because the psychological and the physical relationship between man and woman terminates psychological tension. It also ends the instinctive and psychological energy and leads to the principle of balance between man and woman. For this principle depends on perfection through the general natural marriage law.

Consequently, man and woman must shoulder their responsibility to build a sound righteous society. For they are the source of tranquility, love, affection, and mercy in social life. Acquaintance: The second reason which caused man to build a social life is acquaintance among human beings based on the instinct of social life.

Regarding this view, the philosophers said: "Man is social by nature." Social and psychological experments have shown that man feels tranquility and rest through his social life with others. For this reason Allah, the Most High, said: "So that you may know one another." This phrase shows that there is a human motive behind forming society or social life. Exchanging interests: The third reason for building society, is the exchange of various material interests.

Indeed Allah wanted individuals to be perfect through their psychological, bodily, and intellectual abilities. He also wanted this perfection to be achieved through exchanging interests among individuals. The individual has diverse needs and demands. He cannot secure them all by himself. So, he needs others, and others need him. These differing abilities lead to differing productions and services which the individual offers to others.

Concerning the exchange of these productions, interests, and services, which are offered to satisfy needs, the Qur'an says: "...and We did raise some of them above the others in rank, so that some of them may take the others in subjection;"1 Social function has grown on this base. The principle of the functional social growth has also been explained according to this base. Namely, society grows as bodily organs do.
