Stand up against violence and injustice

This hadith is about the Prophet taking revenge for an injustice done by a Jew. A Jewish man had killed a young girl in order to take her ornaments and the Prophet took it upon himself to punish him for his crime. This hadith teaches us that justice must be served and that no one should be allowed to get away with any kind of injustice. It also shows us that we should not tolerate any kind of violence against innocent people and that we should stand up against it whenever possible.
