Musnad Abu Ya'la al-Mawsili 211:1

Abu Bakr ibn Abi Shaybah narrated to us, Shababah narrated to us, from Shu'bah, from Qatadah, from Abu Ayyub al-'Ataki, from Juwayriyah, that the Prophet, peace and blessings of Allah be upon him, entered upon her while she was fasting on a Friday. He said to her, "Did you fast yesterday?" She said, "No." He said, "Are you going to fast tomorrow?" She said, "No." He said, "Then break your fast."
