Musnad Ahmad 31:27

Ibn Abi ‘Adi narrated to us, from Dawud, from Abu Nadrah, from Abu Sa’id, who said: The Messenger of Allah, peace and blessings of Allah be upon him, commanded us to build the mosque. We began carrying one brick at a time, while ‘Ammar was carrying two bricks at a time, and his head became covered in dust. He said: My companions told me—and I did not hear it from the Messenger of Allah, peace and blessings of Allah be upon him—that he began shaking the dust from his head and saying: "Woe to you, O son of Sumayyah! The transgressing faction will kill you."
