However, developing and extending properties is done in two ways.
From viewpoint of Imam Khomeini, if the goal of increasing the richness is to supply the essential needs of life, to preserve face, to give good service to others and to do good deeds, it will be strongly encouraged.
The leader of contemporary Muslim world stresses that if the goal of increasing richness is the pleasure, lust and other things, it will be discouraged in Islam.
There is also a historical background and roots for the above-mentioned theory in Islamic traditions as well.
Imam Ali (peace be upon him), the truthful successor of the holy prophet of Islam in one of the tradition said as following:
As well as the attention to the spiritual development, Islam focuses on the development of economic fields, since the spirituality and materiality are along with each other.
The culture and spirituality of a society can provide the welfare and economic growth of that society.
This economic growth also can be an appropriate field for mankind's spiritual characterization.
Considering the previous facts, it can be proved that man's growth and prosperity is not only summarized in the economic issues, but it can be regarded as one of the basic elements of man's spirituality.
Therefore, gaining the rich is not considered as an appropriate condition for personal and common welfare but certainly is regarded as a necessary condition.
It is worthy to mention that a researcher recently has published a book about Imam Khomeini's views regarding private ownership. He has delivered a comprehensive analysis regarding the topic.
