The idea is that spending...
The idea is that spending, in general, causes the members of a society to be delivered from perdition. And, on the contrary, when the custom of donation be neglected and the properties be compiled in one pole of the society, there will come forth a majority of the poor and deprived. So, very soon, a great burst happens in the society in which the selves and wealth of capitalists will be burnt by the fire of that revolution.
Here, thereby, the relation of 'donation' and 'prevention of destruction ' is made clear. Therefore, disbursement is useful for capitalist, before it would be beneficial to the state of the deprived; that is, the justification of wealth is a protector of wealth.
Imam Amir-ul-Mu'mineen Ali (a.s.) has pointed to this very fact where he says: "...guard your properties by paying alms tax..." (1) Next to the stage of Holy War and donation, it leads to benevolence and, at the end of the verse, it commands to doing good because the stage of doing good is the highest stage in the course of human development which Islam regards to fully.
It says: "...and do good (to others) , for verily Allah loves the doers of good." The occurrence of this phrase at the end of the verse on donation points to this meaning that the act of donation must be fulfilled with an absolute sincerity and affection: far from any term of reproach or what annoys or hurts the person whom the favour is done to. (1) Nahjul-Balaqah, saying No.
