Musnad Ahmad 1153:1436

I read to Abd al-Rahman: Malik, from Yahya ibn Sa'id al-Ansari, from 'Amrah bint 'Abd al-Rahman, from 'Aishah, the wife of the Prophet, may Allah bless him and grant him peace, that she said: "The Messenger of Allah, may Allah bless him and grant him peace, would pray the morning prayer, and the women would depart wrapped in their garments, not being recognized due to the darkness."
