Upon hearing this, the Messenger of Allah (peace and blessings be upon him) came out and said: "Is the call of ignorance being raised?" The Companions said: "No, by Allah! It is just that one boy struck the other on the back with his hand or foot (and that is why the fight happened)."

If he is an oppressor, then stop him from oppression, that will be help for him, and if he is oppressed, then support and assist him."
