There are 3 degrees of goodness which are demanded, as well as 3 degrees of evils which are forbidden. The first degree of goodness is to do justice (" 'adl"), which is returning good for good. The next is is to do good ("ihsan") where the doer of good does not receive any benefit in return. The highest degree of goodness is where goodness becomes second nature to a person, where he would do good to all humanity whom he treats as his kindred.
The first degree of evil is doing shameful deeds (or indecency - "fahsya"), which does not necessarily affect others. The next degree of evil is denying truth or the doing anything which is not agreeable with the truth ("mungkar"). This may affect others. The highest degree of evil is committing of acts of tyranny or oppression (rebellion -"baghy"), which affect many and numerous people, including a nation or state.
In short, justice is demanded while oppression and injustice are considered evil. God admonishes the people (or group of people) who commit the later. Let this be a reminder to all of us and to our Government.
