It is narrated from Hazrat Hudhaifa (may Allah be pleased with him) that once the Noble Prophet (peace and blessings be upon him) said: After me, there will come some rulers who will act with falsehood and commit oppression. So whoever goes to them and declares their lies as truth and helps them in their oppression, he has no connection with me and I have no connection with him, and he will not be able to come to me at the Pond of Kawthar. And whoever does not confirm their lies nor helps them in their oppression, then he is from me and I am from him, and he will come to me at the Pond of Kawthar.
