Musannaf Ibn Abi Shayba 2:241

Abu Bakr narrated to us, he said: Zayd ibn al-Hubab narrated to us, from Malik ibn Anas, from al-Zuhri, from ‘Ata’ ibn Yazid, from Abu Sa‘id al-Khudri, that the Prophet, may Allah bless him and grant him peace, used to say the like of what the mu’adhdhin (caller to prayer) says.
