345. Chapter: It is disliked to single out Friday to fast or Friday night for praying at night

1760. Abu Hurayra reported that the Prophet, may Allah bless him and grant him peace, said, "Do not single out the night of Jumu'a rather than other nights for praying at night and do not single out the day of Jumu'a for fasting rather than other days unless it forms part of a fast that one of you is fasting." [Muslim]

1761. Abu Hurayra said, "I heard the Prophet, may Allah bless him and grant him peace, say, 'None of you should fast on the day of Jumu'a unless he fasts a day before or after it.'" [Agreed upon]

1762. Muhammad ibn 'Abbad said, "I asked Jabir, 'Did the Prophet, may Allah bless him and grant him peace, forbid fasting on the day of Jumu'a?' He said. 'Yes.'" [Agreed upon]

1763. Umm al-Mu'minin, Juwayriya bint al-Harith said that the Prophet, may Allah bless him and grant him peace, visited her on the day of Jumu'a and she was fasting. He said, "Did you fast yesterday?" She said, "No' He said, "Do you intend to fast tomorrow?" She said, "No." He said, "Then break the fast."[al-Bukhari]
