“I heard ‘Aishah say: ‘I used to owe fasts from the month of Ramadan, and I would not make them up for until Sha’ban came.’”  

سَمِعْتُ عَائِشَةَ تَقُولُ إِنْ كَانَ لَيَكُونُ عَلَىَّ الصِّيَامُ مِنْ شَهْرِ رَمَضَانَ فَمَا أَقْضِيهِ حَتَّى يَجِيءَ شَعْبَانُ  

“We used to menstruate at the time of the Prophet ﷺ, and he would order us to make up for the (missed) fasts.’”  

كُنَّا نَحِيضُ عِنْدَ النَّبِيِّ ﷺ فَيَأْمُرُنَا بِقَضَاءِ الصَّوْمِ
