Abdullah bin Khabbab (may Allah have mercy on him) narrated from his father: We were sitting at the door of the Prophet (peace and blessings be upon him) when he (peace and blessings be upon him) came out to us and said: "Do you hear?" We said: We have heard it two or three times. He (peace and blessings be upon him) said: "Soon there will be rulers over you; do not believe them in their lies, nor help them in their oppression, for whoever believes them in their lies and helps them in their oppression will not come to me at my Pond (al-Hawd)."
