Musnad Abu Ya'la al-Mawsili 150:138

Harun ibn Ma'ruf narrated to us, Abdullah ibn Wahb narrated to us, Usamah ibn Zayd informed me, from Ibn Shihab, from Urwah, from Aisha. And Usamah ibn Zayd narrated to me that Hafs ibn Ubayd Allah ibn Anas narrated to him, saying: I heard Anas ibn Malik saying: The Messenger of Allah (peace be upon him) said: "Shall I not inform you of the prayer of the hypocrite? He delays the Asr prayer until, when it is between the two horns of a devil—or upon the two horns of a devil—he stands and pecks them like the pecking of a rooster, not remembering Allah in them except a little."
