Everyone has his own definition of justice. The justice that is acceptable by you may not hold by you for others

e.g if you work for one month you expect a pay of 10000 supposedly and if a laborer works all day in the open sun for one month you expect to pay him 900 and call it justice.
or a person who puts gas in your car you give him one riyal and call it justice

So my dear QLers when you cannot justify your actions how can you be the judge and the rewarder.
Justice is a very delicate path. Let God be the judge
