حَدَّثَنَا أَحْمَدُ بْنُ عَبْدِ اللَّهِ بْنِ يُونُسَ ، حَدَّثَنَا زُهَيْرٌ ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ ، عَنْ أَبِي سَلَمَةَ ، قَالَ : سَمِعْتُ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا ، تَقُولُ : " كَانَ يَكُونُ عَلَيَّ الصَّوْمُ مِنْ رَمَضَانَ ، فَمَا أَسْتَطِيعُ أَنْ أَقْضِيَهُ إِلَّا فِي شَعْبَانَ الشُّغْلُ مِنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، أَوْ بِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ " ،
Abu Salama reported: I heard 'A'isha (Allah be pleased with her) as saying: I had to complete some of the fasts of Ramadan, but I could not do it but during the month of Sha'ban due to my duties to the Messenger of Allah (ﷺ) or with the Messenger of Allah (ﷺ) .
