Musannaf Ibn Abi Shayba 3:4946

Abu Usama and Ibn Numayr narrated to us, from Sa’d ibn Sa’id, who said: ‘Amra informed me, from ‘Aisha, who said: The Messenger of Allah (may Allah bless him and grant him peace) forbade two prayers: a prayer after the dawn breaks until the sun rises and ascends, for it rises between the two horns of a devil; and a prayer after the afternoon (Asr) until the sun sets, for it sets between the two horns of a devil.
