To clean the wealth, Islam instituted the zakat system ( way of purifying wealth ). A person whose wealth has reached a certain point is obligated to pay zakat ( alms ) which is a duty enjoined by God and undertaken by Muslims in the interest of society as a whole. For those able persons whose wealth does not reach the minimum rate point, he can also give voluntary contribution to the needy . This does not mean that the needy should always be receiving help from the able. Prophet Muhammad said :" The upper hand ( glver ) is better than the lower one ( receiver of help ) ." If the receiver of zakat can grasp the spirit of the Prophet's saying, he will try his best to be the giver instead of the receiver by endeavouring to better his life as encouraged by the teachings of Islam. In Islam the possession of more wealth does not raise a man's dignity, nor does poverty degrade him. It is true that wealth is necessary for man to live on this earth, but it is only a means, not the end. The end is happiness in life by attaining the higher values and not losing sight of in the pursuit of wealth . Among the great virtues of Islam is the command to do good and the prohibition to do evil. The good should be preserved and the evil should be discarded. In short, Islam is actually composed of a series of commands and prohibitions. All the commands and prohibitions are for the good of humanity. Allah the Most Knowing, the Most Merciful, did not decree any law and regulations but for the good and benefit of his creatures.
The prohibition was decreed because of its evil implications to humanity. The evils were created to test the human conscience and challenge their freewill in choosing between right and wrong. All the commands and prohibitions from Allah as transmitted through His Prophet Muhammad ( peace be upon him ) was intended to purify the human soul in order to live a pure and clean life adored by Allah and human genesis.
