Musnad Ahmad 938:86

'Affan narrated to us, Hammam narrated to us, Qatadah narrated to us, from Ibn Sirin, from Zayd ibn Thabit: That the Prophet, peace and blessings of Allah be upon him, forbade praying when the horn of the sun rises or when its horn sets. And he said: "It rises between the horns of a devil," or "from between the horns of a devil."
