Jabir ibn Sulaim reported: The Prophet, peace and blessings be upon him, said, “Beware of pride, for Allah does not love pride. If a person abuses and reviles you in a matter he knows about you, then do not revile him in a matter you know about him, for then you will have his reward and he will have your sin. Thus, do not revile anyone.”
