On the other hand...
On the other hand, man's thankless attitude to God, of which social injustice is the out-ward expression or symptom, results in the ruin of economic resources and productivity as well as degeneration of man's social existence. [^30] Islam also expedites the social drive toward production in its religious regulations. Under die Islamic economic system, earning is exclusively linked to working. All other means of earning and ownership are abolished.
The possession of natural resources is not considered legitimate without continuous human efforts to develop it. Any type of earning that does not require any human labour, in commerce as well as in production, is forbidden. For this reason, the use of financial capital to generate earning is abolished-The only legitimate way to make use of capital is to invest it in production and share the risk of profit and loss.
To insure the utilization of capital in economic development, Islam strongly forbids the hoarding of money and initiates a yearly tax to downgrade any wealth that is not enrolled in the production process. Additionally, any type of useless economic activities, such as gaming, magic and jugglery, are forbidden in Islam.
[^31] Furthermore, Islam makes it a requirement for Muslims to explore all fields of knowledge and seek any efficient means of production in order to utilize to maximum benefit the natural resources of the environment. [^32] The economic strength of Muslims is analogous to their military strength. The power of the Islamic State is judged on the merit of its economic progress and social prosperity.
Here Sadr gives his interpretation of two sets of apparently contradictory prophetic traditions of which some exhort austerity and reject materialistic gains, and others invite man to make use of wealth for his benefit. He sees no contradiction between the two when the former is looked at as discouraging man from making economic wealth as the final objective of his life. See Iqtisaduna 669-672.
