Musannaf Ibn Abi Shayba 2:171

Shababa narrated to us, from Ibn Abi Dhi'b, from al-Zuhri, who said: It reached us that men from the companions of the Prophet, may God bless him and grant him peace, one of them, when he prayed in his house, would perform the first call to prayer (adhan) and the second call (iqamah) for every prayer.
