Musannaf Ibn Abi Shayba 2:172

Abu Bakr narrated to us, he said: Abu Mu'awiyah narrated to us, from al-A'mash, from Ibrahim, from al-Aswad and Alqama, who said: We came to Abdullah in his house, and he said: "Do these people pray behind you?" We said: "No." He said: "Then stand up and pray," and he did not command an Adhan nor an Iqamah.
