Musnad Abu Ya'la al-Mawsili 42:328

Abu Khaythama narrated to us, Waki' narrated to us, Malik bin Anas narrated to us, from Ayyub bin Habib, the freed slave of Banu Zuhrah, from Abu al-Muthanna al-Juhani, who said: I was with Marwan bin al-Hakam when Abu Sa'id al-Khudri came. Marwan said to him, "Did you hear the Prophet, may Allah bless him and grant him peace, forbidding blowing into a drink?" He said, "Yes."
