karma

Q: My question is concerning justice for the wronged. Why are people who have wronged me doing very well while I am struggling to strive? What happened to karma of what goes around come around? What is the Islamic ruling on karma?

Q: Please can you comment in the Islamic ruling or stance on Karma. Can you please also advise what is the stance on using the term karma. For example if someone does wrong to you, to tell that person karma will get you.
