Musannaf Ibn Abi Shayba 3:4948

Abu Dawud narrated to us, from Shu'bah, from Simak, who said: I heard al-Muhallab ibn Abi Sufrah narrating from Samurah ibn Jundub that the Messenger of Allah (may Allah bless him and grant him peace) said: "Do not pray," or he said: "The Messenger of Allah (may Allah bless him and grant him peace) forbade praying after the morning prayer until the sun rises, for it rises between the two horns of a devil, or upon the horn of a devil."
