Narrated 'Abdullah: Allah's Messenger ﷺ said, "Whenever a person is murdered unjustly, there is a share from the burden of the crime on the first son of Adam for he was the first to start the tradition of murdering".
The Prophet Muhammad also taught us about mercy and compassion towards others as well as justice and fairness in our dealings with one another. He reminded us that no matter who commits an act, whether it be good or bad, everyone will be held accountable for their actions in front of Allah on Judgment Day. Therefore, it is important for us to strive towards justice so that no one can commit any kind of injustice without being punished accordingly.
