Musnad Abu Ya'la al-Mawsili 50:1

Mus'ab ibn 'Abd Allah al-Zubayri narrated to us, Malik ibn Anas narrated to me, from Zayd ibn Aslam, from 'Ata' ibn Yasar, from 'Abd Allah al-Sunabahi, that the Messenger of Allah (may Allah bless him and grant him peace) said: "Indeed, the sun rises and with it is the horn of a devil. When it rises high, it leaves it. When it is at its zenith, it accompanies it. When it passes the meridian, it leaves it. When it draws near to setting, it accompanies it. When it sets, it leaves it." The Messenger of Allah (may Allah bless him and grant him peace) forbade prayer during those hours.
