Musnad Ahmad 31:469

'Abd al-Rahman narrated to us, Zuhayr narrated to me, from Zayd ibn Aslam, from 'Abd al-Rahman ibn Abi Sa'id al-Khudri, from his father, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "When one of you stands to pray, let him not allow anyone to pass in front of him. If he refuses, let him fight him, for he is only a devil."
