Musnad Abu Ya'la al-Mawsili 147:35

Muhammad ibn Abd Allah ibn Numayr narrated to us, Rawh narrated to us, Usamah ibn Zayd narrated to us, from Hafs ibn Ubayd Allah, from Anas, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "Do not pray at the rising of the sun, nor at its setting, for it rises and sets between the horns of a devil. And pray between that as you wish."
