In summary...
In summary, we can assert an important fact in the world of economics, as clearly stated by Islam and known as the cause behind the problem of wealth distribution, is man's self-centeredness and his greed. For the worlds of the holy Qur'anic verses and Prophetic traditions lay great stress on avarice and greed as the root causes of the economic problems in the fields of distribution and consumption.
This view rules out the effect of external conditions, including means of production, whether in abundance or scarce, and distribution, for man, himself, controls distribution, His will controls it. His awareness identifies his view of justice, the value of money and wealth and the meaning of life. It is this very awareness that principally outlines the way he adopts in dealing with himself and others.
Everywhere and every time subjective factors are the root causes of the problems and the sources of economic injustice, regardless of the variation in conditions, means and quantity of production, which tend themselves to be by-products resulting from the original misdiagnosis.
The only way to save man from economic injustice and confusion is his daily life, re-shaping his existence and re-formulating his conceptions, his view of life, money, wealth, profit and moral pleasure, in a sound and objective way and in harmony with the Qur'an and in agreement with its deep, analytical views. Allah, the Exalted, says: “...
surely Allah does not change the condition of a people until they change their own condition; ...” Holy Qur'an (13:11) Unless an independent, economic system is adhered to this, change cannot be fully successful; a system, which takes upon itself the task of re-distributing human wealth and managing economic life in agreement with the principles of Islamic justice and equality and not on high-fluting theories that lose the essence of what the basic problem is: Allah, the Exalted, says: “And that if they should keep to the (right) way, We would certainly give them to drink of abundant water.” Holy Qur'an (72:16) “And if the people of the towns had believed and guarded (against evil) We would certainly have opened up for them blessings from the heaven and the earth ...”Holy Qur'an (7:96) There is no way to better man's life other than effecting a complete, psychological and ideological transformation.
