Abu Huraira reported God’s messenger as saying, “It is not allowable for a woman to fast when her husband is present without his permission,* and she may not allow anyone to enter his house without his permission.”
*This refers not to Ramadan, but to a supererogatory fast.
عَنْ عَائِشَةَ قَالَتْ: كَانَ يَكُونُ عَلَيَّ الصَّوْمُ مِنْ رَمَضَانَ فَمَا أَسْتَطِيعُ أَنْ أَقْضِيَ إِلَّا فِي شَعْبَانَ. قَالَ يَحْيَى بْنُ سَعِيدٍ: تَعْنِي الشّغل من النَّبِي أَو بِالنَّبِيِّ صلى الله عَلَيْهِ وَسلم
‘A'isha said that when she had some part of the fast of Ramadan to make up she would be able to do so only in Sha'ban. Yahya b. Sa'id said she meant this was due to her being kept from it by her duty to the Prophet.
Mu'adha al-‘Adawiya said that when she asked ‘A'isha why one who has been menstruating must make up for her fast but not for her prayer, she replied, “That happened to us, and we were ordered to make up for the fast, but were not ordered to make up for the prayer.”
Hamza b. ‘Amr al-Aslami told God’s messenger that he found himself strong enough to fast while travelling and asked whether it would be wrong for him to do so. He was told that licence had been given by God who is great and glorious, so that if anyone acted upon this he did well, but if anyone wished to fast he would not be guilty of sin.
