Musnad Ahmad 1153:1108

Muhammad ibn Ja‘far narrated to us, Shu‘bah narrated to us, from al-Miqdam ibn Shurayh, from his father, who said: I asked ‘Aishah about the prayer after the ‘Asr [prayer]. She said: "Pray. The Messenger of Allah, may Allah bless him and grant him peace, only forbade your people, the people of Yemen, from praying when the sun rises."
