Musnad Abu Ya'la al-Mawsili 110:95

Ali ibn al-Ja'd narrated to us, Shu'bah narrated to us, from 'Amr ibn Murrah, who said: I heard Yahya ibn al-Jazzar from Ibn Abbas: That the Prophet, peace and blessings of Allah be upon him, was praying, and one of us wanted to pass in front of him, so he began to ward him off.
