It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said to Sayyiduna Ka'b bin Ujrah (may Allah be pleased with him): "O Ka'b bin Ujrah, I seek refuge for you with Allah from the rule of the foolish." He said: O Messenger of Allah, what is the rule of the foolish? He (peace and blessings be upon him) said: "There will be rulers after me; whoever goes in to them, affirms their lies and helps them in their oppression, then he has nothing to do with me and I have nothing to do with him, and he will never come to me at the Pond (al-Kawthar)."
