Musannaf Ibn Abi Shaybah 9497 — What is mentioned on fasting Friday

Abu Ayyub al-Ataki narrates from Sayyidah Juwayriyah (may Allah be pleased with her) that once the Prophet (peace and blessings be upon him) visited her on a Friday, and she was fasting. The Prophet (peace and blessings be upon him) asked her: "Were you fasting yesterday?" She said: "No." He asked: "Do you intend to fast tomorrow?" She said: "No." The Prophet (peace and blessings be upon him) said: "Then break your fast."
