It is narrated from Sayyiduna Ka'b bin Ujrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Soon rulers will be placed over you. Whoever frequents their doors, helps them in their injustice and affirms their lies is not from me and I am not from him, and he will never come to the Pond. And whoever does not frequent their doors, does not affirm their lies and does not help them in their injustice is from me and I am from him, and he will be one who comes to the Pond."
