The exact expression can be found in many ahadith, which have been mentioned in Shiite and Sunni resources. And it is understood from them entirely, that one of the clearest signs of this revolution is this matter. Here, one question is asked that do “oppression” (ظلم) and “injustice” (جور) have any difference that these two words have been emphasized repeatedly?
It is understood from the root of these words that violating the right of others has two types, that there is one separated word for each of them in Arabic literature.
The first one is that a person takes others right for him/her and usurps the results of others’ efforts; it is called “Oppression” The other one is to take others’ rights and to give it to another people and to dominate the person’s adherents over the lives and honors and assets of people for strengthening the bases of the power, and to take power by unjust discriminations, it is called “injustice”.
The antonym of “oppression” is “fair distribution” (قسط) and the antonym of “injustice” is “justice” (عدل).[^1] Anyway, when “violation” of others’ rights, from one side, and “discriminations”, from the other side, fill the human society, he appears and removes all of them. What have been said above were generalities about the sweeping corruption as a factor of mutation and revolution, which is predictable in any kinds of revolution.

For instance, tens of these corruption, which a part of them have social and political aspect and another part has moral aspect, have been mentioned in a narratives from Imam Sadiq(as) that studying them makes the human to think deeply about the issue.
