...When anyone kills a civilian or harms others or dishes out justice outside of the juristiction of a legal system, they are known as bandits. In the study of Islamic Shariah, the terminology given for these people is "Muharib" and the punishment for a muharib is as severe as for someone who commits treason.
In short, these people are NOT fulfilling a religious obligation but venting their frustration which comes about as a result of perceived injustices, poverty, lack of education and unfairness.
So Mohan Mohan, instead of harbouring hate for Muslims and "Pakis", why dont you start working towards creating some goodwill so that per chance the next generation of Hindu-Muslims, Indian-pakistanis can live side by side in peace.
