Malik Muwattaحَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، أَنَّهُ سَمِعَ عَائِشَةَ، زَوْجَ النَّبِيِّ صلى الله عليه وسلم تَقُولُ إِنْ كَانَ لَيَكُونُ عَلَىَّ الصِّيَامُ مِنْ رَمَضَانَ فَمَا أَسْتَطِيعُ أَصُومُهُ حَتَّى يَأْتِيَ شَعْبَانُ
Yahya related to me from Malik from Yahya ibn Said from Abu Salama ibn Abd ar-Rahman that he heard A'isha, the wife of the Prophet (ﷺ) say, "I used to have to make up days from Ramadan and not be able to do them until Shaban came."
