Musnad Abu Ya'la al-Mawsili 149:11

Shayban ibn Farrukh narrated to us, Tayyib ibn Salman narrated to us, he said: I heard ‘Amrah, she said: And I heard ‘Aishah saying: Indeed, the Messenger of Allah (may Allah bless him and grant him peace) used to forbid *wisal* (continuous fasting without breaking it) in fasting. And he used to command the hastening of the breaking of the fast and the delaying of the *suhur* (pre-dawn meal).
