Musnad Ahmad 31:872

Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, he said: I heard Qatadah narrating from Sulayman, or Abu Sulayman, and Hajjaj said: Shu'bah narrated to me, and a man from Quraysh said: From Abu Sa'id al-Khudri, from the Prophet, peace and blessings of Allah be upon him, that he said: "There will be commanders who will be surrounded by attendants or followers from the people who will commit injustice and lie. Whoever aids them in their injustice and believes their lies, he is not of me, nor am I of him. And whoever does not believe their lies and does not aid them in their injustice, then I am of him and he is of me."
