Book 67: Wedlock, Marriage (Nikaah)
Chapter 84 A woman should not observe Saum except husband's consent (is 'with her' missing here?)

Sahih al-Bukhari 5192
Narrated Abu Huraira:
The Prophet (ﷺ) said, “A woman should not fast (optional fasts) except with her husband’s permission if
he is at home (staying with her).
حَدَّثَنَا مُحَمَّدُ بْنُ مُقَاتِلٍ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم ” لاَ تَصُومُ الْمَرْأَةُ وَبَعْلُهَا شَاهِدٌ إِلاَّ بِإِذْنِهِ ”.
