Musnad Ahmad 647:0

And among that in which Sulayman ibn Surad and Khalid ibn 'Arfatah joined is: The Messenger of Allah (ﷺ) said: "There will be after me leaders who will lie and commit oppression. Whoever believes their lies and supports them in their oppression, he is not of me, and I am not of him, and he will not reach the Hawd (the Cistern). And whoever does not believe their lies and does not support them in their oppression, he is of me, and I am of him, and he will reach the Hawd."
